IOMEGA COOKBOOK Special Hints for Using your Bernoulli 150 with the Amiga. 1. Who is Iomega? Iomega Corporation is a company that manufacturers removable mass storage products. Iomega is located in Roy, Utah, 30 minutes north of Salt Lake City. Iomega's current product line includes: the Bernoulli Multidisk150 MB Drive, The Tape 250 Backup Drive, Floptical 21 MB Drive, and the LaserSafePlus 1.3 GB Magneto Optical Drive. Iomega's flagship product is the Bernoulli. Iomega has been making Bernoulli Products for over 12 years, beginning with the original 8 inch 10 megabyte drives. 2. What is a Bernoulli? A Bernoulli drive is a removable cartridge based storage system (Currently 150MB) that uses a flexible magnetic medium to store data. The flexible medium incorporates state of the art fluid dynamic techniques to fly the media close to the read/write heads of the drive, while maintaining a millionth of an inch gap between them. When the drive is subjected to shock or is jarred, the media falls safely away from the head, thus preventing the unwanted hard drive "Head Crash". The cartridges are rugged and can easily withstand an 8 foot drop without any repercussions. The drive is a SCSI device that touts hard drive speeds, and compatibility with many computer systems. With speeds of a hard drive, ruggedness and durability of your average tow truck, removability and transportability of a floppy, and storage that grows with you, the Bernoulli has become a very popular peripheral. 3. What is SCSI? SCSI is an acronym that stands for Small Computer System Interface. SCSI allows a user to attach up to seven devices on one controller card. Many hard drives, removable drives, CD-Rom drives, and scanners are SCSI devices. SCSI uses and ID number to distinguish between multiple devices on a single computer. No two devices on the same chain should share a SCSI ID number. Most controller cards use SCSI ID seven. Hard drives are typically set to SCSI ID#0, or SCSI ID#6. A commonly misunderstood part of SCSI is termination. For more information see Termination below. With SCSI, cabling is a very important issue. No one section of cable should exceed six feet. Total Cable length of the chain should not exceed 19.6 feet. Cables should be heavily shielded and use sturdy molded connectors. 4. What is termination? Termination is method by which electrical signals are controlled to prevent noise, and a phenomenon called standing waves. The best analogy of termination and SCSI is that the SCSI chain is like a pipe with water in it. In order for the water to flow properly, both ends need to be plugged to prevent water from leaking out and to prevent foreign materials from seeping in. At the same time, the rest of the pipe needs to be free from obstruction in order for the water to flow freely. Only the first and last devices in the Scsi chain should be terminated. Usually the first internal device or the internal device that is electrically the farthest from the controller card is considered the first of the chain. The last external device (electrically) from the computer is considered the last device in the chain. Both devices need to be terminated. There are two types of termination. The first type is Active Termination. This type of termination uses transistors that can actively monitor line levels and adjust their effectiveness accordingly. Active termination is usually activated and deactivated via and external switch labeled termination. This type of termination gets its power from the SCSI device. The second type of termination is Passive Termination. This type uses resistors instead of transistors. They have a fixed value and cannot adjust themselves to current line conditions. Passive Termination can be in the form of RSIPs (Resistor Single In-line Package) and look like an 8 legged centipede that has been cut lengthwise. There will be three of these together, as 3 are needed to do the job. Also, Passive Terminators can come in the form of a SCSI Plug or pass through cap that looks like a SCSI cable, without the cable. 5. Bernoulli and Amiga OS. The Amiga Operating System, or AMIGADOS is a blend of conventional pc dos and UNIX. The graphical user interface is called Workbench. The Amiga OS is a very powerful multitasking environment, that when harnessed can perform amazing tasks. Incredibly, it can provide this environment with very little memory usage. The Bernoulli, on the Amiga, acts much like a hard drive and a floppy drive combined. As in UNIX, volumes (or Disks) are Mounted and Unmounted. Hard drives usually only mount, and never unmount. Unlike UNIX, the Amiga performs most of these tasks transparently and automatically. In the early days of AMIGADOS, most devices were required to have a Mountlist entry that would describe the device by breaking it down into its components. i.e. # of Tracks, # of Cylinders, etc. To an extent, the Mountlist entry is still being used today. However, most hard drives, and other SCSI type devices store this information directly on the drive in a special location called the Rigid Disk Block or RDB. A sample Mountlist for a Bernoulli 150 would look like this: Device = gvpscsi.device FileSystem = L:Fastfilesystem Unit = 001 Flags = 0 Surfaces = 1 BlocksPerTrack = 138 Reserved = 2 Interleave = 0 LowCyl = 2 HighCyl = 2137 Buffers = 32 BootPri = -15 GlobVec = -1 BufMemType = 0 Mask = 0xFFFFFFFE MaxTransfer = 0x7FFFFFFF Mount = 1 DosType = 0x444F5301 StackSize = 4000 HDToolbox, Commodore's hard drive prepping utility, will set up a drive type and read this information directly from any SCSI device that supports the SCSI inquiry command. In other words, rather than try to hunt down all of this info, most hard drive prepping utilities will figure it out for you. After all the information is acquired, the prepping program will in one way or another prompt you to "save changes to disk", or "write partition info to disk", etc. This stage of the prepping process actually puts the RDB information onto the disk. The big advantage of using the RDB method is that it makes devices used on one computer almost 100% compatible with another computer, even if it uses a different SCSI controller. In essence, it is a universal driver. 6. Devices, Partitions, Assigns, Volumes??? What is all this stuff? Well, these are the different methods by which the Amiga can address different storage units. Devices are devices. They are the base unit of a storage medium. In other words... the floppy drive is a device, and its device name can be DF0, DF1, DF2, DF3 depending upon how many floppy drives you have. Floppy drives do not use partitions. With hard drives, partition names and device names are usually the same. A partition is a division on a hard drive. Each partition should have its own name so that you and the computer can distinguish between them. If the names are not different, the computer will differentiate between them by appending a .0 to the second name. In other words, if you have two DH0 partitions on your computer, the computer will refer to one of them as DH0.0. Volume names are superficial names used for us humans. We give a certain disk or device a Volume name that we like. This is a label (it will show up on the workbench) that we can keep track of things with. Assigns are a way of fooling a computer into thinking that a certain drawer or folder on one of our drives is actually a device. If you have a drawer called ADPRO that is in the Graphics drawer inside of the Applications drawer on you disk called Work, it would be a hassle to have to dig through all of those drawers to find it. You can use an assign to make ADPRO Think that it is its own drive. The advantage is that you can simply type ADPRO: at the command line, and it will go right to that drawer for you. 7. Do I need any special software for the Bernoulli on the Amiga? No. Any software drivers that you will need will come with your SCSI controller card. Additional software such as SCSI Mounter is recommended to enhance performance, but is not necessary. Most newer SCSI controller cards, and even older ones with new ROM upgrades on them will recognize the Bernoulli. Use the prepping and formatting software that comes with your controller card. 8. Can the Bernoulli be used as a Boot drive? Yes. As a matter of fact, it is perfect for people who use multiple operating systems, and want to boot their computer in another system. There are two methods to setting the Bernoulli as a boot device on an Amiga. First you must have your SCSI controller set to bootable mode. (Most come this way.) The Amiga uses a priority system to tell the computer which is the boot device. For instance, a floppy has the highest priority at +5. A Boot hard drive is typically 0 or +1. All other drives are usually set well below these two at some negative number, typically -10. This information is stored in the Rigid Disk Block section of a disk. Thus you would use your hard drive preparation program (HDToolbox, GVP FastPrep, etc.) to set this priority. The computer will then boot from the device that has the highest priority. This value can usually be changed without affecting the data on the disk if special care is taken. The second method is better. However, it is limited to AmigaDos 2.0 or higher. This version still relies upon the boot priority to inform the computer about the default settings, however, it can be overidden during a cold or warm boot. This is done by simply holding down the two mouse buttons during a boot. After a "Boot Menu" appears, you will see an opportunity to select a device to boot from. Simply choose the device you wish to boot from, and then select boot. 9. Should I low level format the Bernoulli? It is not necessary to low lever format the Bernoulli drive on the Amiga. While operation can work, on occasion I have seen people totally trash a disk. Usually this is caused by aborting out of a low level format. This type of format is a drive function, not an Amiga Dos function, and serves little purpose on the Bernoulli. It also is a very lengthy process and can take anywhere from 20 minutes to 3 hours. The Bernoulli has its own internal methods for determining blocks that go bad, and reallocation of bad sectors. 10. How do I switch between Bernoulli disks if I have more than one? One method is by rebooting your computer after every disk change. This is not very practical however. Some controller cards, such as the GVP series have great support for disk change and for removable media. On these controllers, it is virtually automatic. One special tip is to name all of your disks with the same partition name and giving them exactly identical partition structures. If you cannot or choose not to follow those guidelines, or have a controller card that does not support removable media well, there is a shareware program called SCSI Mounter, that will solve most problems for you. You can obtain this software from many Bulletin Board Services, including Iomega's. Iomega's BBS Number is (801) 392-9819. Look for it in the Amiga files section. If you are attempting to switch between two disks, and one or more of them are MSDOS formatted, then you will need to use the DISKCHANGE command from CrossDos. If you have installed CrossDos, it is located in the System Drawer. 11. Can I trade Information with another Amiga User if they have a Bernoulli? Yes. You can even exchange data even if the other user does not own a Bernoulli. The external Bernoulli, better known as the Transportable, can be connected to any Amiga with an RDB compliant SCSI port. You can easily move large chunks of data back and forth just by taking your drive with you. 12. Does the Bernoulli spin down into sleep mode? Yes. As with many new drives on the market, our drive is compliant with the EPA's new energy saving system. After 30 minutes of inactivity, the drive will spin down and go into a sleep mode. This also helps to enhance the life of the media. Unfortunately, there have been reported cases of problems that appear to be directly linked to the Bernoulli spinning down. This occurs mostly on Amiga 3000 computers and on A2091 controller cards; both use the Western Digital SCSI chip. The problem has been traced to the 'reselection' command. When the drive spins down, it disconnects itself from the SCSI bus. When you attempt to access the disk, the drive spins back up, but is not allowed to reconnect to the SCSI bus. A solution to this problem lies in the formatting of the disks. HDToolbox has an option to turn the 'Reseleciton' support off. By turning this support off, during spin down, the drive remains connected to the SCSI bus, and will not have trouble getting the controller to let it reconnect. The "Supports Reselection" option is under the "Change Drive Type" and under either "Edit old drive type" or "Define new drive type" windows. There is a box next to the sentence that says "Supports Reselection". Set this to no. Newer versions of the Bernoulli 150 (revision T.50 or above) have expanded code in them that will prevent this problem. It eliminates the need to turn the reselection flag off as it can deal with many different interpretations of the reselection command. Drives before revision T.50 will still need this flag turned off. 13. Will CrossDos work with the Bernoulli?? Yes. However, you must use the commercial version of CrossDos, not the version that is included with the newer operating systems. The version that is included with the newer operating systems provides floppy support only. The commercial version, called CrossDos Plus, has support for hard drives, Bernoulli drives, and Flopticals, and comes with CrossPC as a bonus. CrossPC is a software based IBM emulator that will allow you to run MS-Dos 5.0 and compatible software on your Amiga. 14. How do I set up CrossDos to work with my Bernoulli? CrossDos has an installer that will do this for you. It has an option to "Configure a 100% MSDOS partition for use with CrossDos and CrossPC". Select this option and follow the steps through. It will also give you the opportunity to install for real or practice. I suggest you practice once through. You will need to have an Amiga formatted disk in the Bernoulli Drive while running the installer. This will make it easier for CrossDos to set up the Bernoulli for use with an MSDOS Disk. I recommend flipping the write protect switch on the Amiga formatted Bernoulli into the Protect mode to prevent any possible mishaps. CrossDos will essentially set up a mountlist entry for the Bernoulli. Usually this entry is labled PCC. It puts this entry in your DosDrivers drawer which is located in the Devs directory. This PCC file can be edited with a text editor. Once you have created this file, the next time you boot your computer with a dos disk in the Bernoulli, the MSDOS Icon should appear. CrossDos expects the Disk to be at the same SCSI ID# everytime. 15. Can I use an MSDOS Bernoulli disk to boot CrossPC? Yes. Make sure you use the installer to configure the Bernoulli for use with a 100% MSDOS partition. In fact, I have actually be able to have many Bernoulli drives working with CrossPC at the same time. I simply edited the information window for the CrossPC Icon to set C=PCC, D=PDC, E=PEC, etc. 16. I heard that the Bernoulli Disks come preformatted in MS-DOS. Is this true? Yes. When the disks leave the factory, they are shipped with an MS-DOS format on them. Thus, if you wish to use them for CrossDos or as a PC disk, there is no need to format them. 17. I need to interchange data with a real PC. How do I connect my Bernoulli to it? Interfacing with a PC can be a real nightmare. Most PC's do not come with a built in SCSI interface and unlike the Amiga or Mac, not all SCSI interfaces on the PC are compatible. Iomega uses ADAPTEC compatible SCSI adapter cards, and has found them to be the very compatible with the many SCSI devices available. If you wish to interface with multiple PC computers, you may want to consider Iomega's PC parallel port adapter. This adapter will connect to almost any standard IBM PC compatible computers printer port. Since most PC's have printer ports, this makes it very universal. For more information contact Iomega's Sales support. 18. Will the parallel port adapter work with the Amiga computers? No. A special software drive would be needed in order to support this feature. There have been rumors of some third party software developers for the Amiga that have considered writing the drivers, but as of yet nothing has materialized. 19. Is the parallel port adapter (for the IBM PC's) as fast as SCSI? As a general rule, no. However, with the newer improved high speed parallel ports, their speeds will theoretically allow for near SCSI transfer speeds. 20. Many people have asked for a sample MountFile Entry for CrossDos. Here it is: /* MountFile Entry for full MS-DOS Disk. * * Disk Size: 143.9 Meg * Vendor and drive name: 000 IOMEGA BETA150 */ Surfaces = 1 BlocksPerTrack = 138 LowCyl = 0 HighCyl = 2136 DosType = 0x4d534800 BufMemType = 1 Device = "2nd.scsi.device" Unit = 0 Flags = 0 FileSystem = L:CrossDOSFileSystem Mask = 0x7ffffffe MaxTransfer = 0x00ffffff BlockSize = 512 StackSize = 2000 Priority = 5 GlobVec = -1 Buffers = 5 Activate = 1 21. Will my Bernouli work with a PC Bridgeboard? As far as we know, yes. There may be some problems using it as a boot device, however. As with real PC's, there are booting limitations with SCSI devices. You must have the Device set to SCSI id#0. This may be true with the Bridgeboard as well, but I do not have a bridgeboard that I can confirm this with. 22. How do I transfer data from my Amiga to a Macintosh? One of the best ways is by using an MSDOS disk as a medium of exchange. Using CrossDos on the Amiga and using a similar program for the Mac called Access PC. There is a trick to moving files back and forth. One thing that you must always remember is that the file you are moving must work on the other platform once you get it there. The Bernoulli is just a messenger. If it brings a bad message that the other computer won't understand, then you have accomplished nothing. Text files and ascii based files are the worst. An example of ASCII files are basic DOS text, DXF 3D files and ASCII based postcript files. These are the most frustrating. Why? Because the Macintosh, the Amiga and the PC all use different end of line markers or carriage returns and line feed markers. CrossDos has a translator that will assist in moving these types of files back and forth. The CrossDos translator has a preference icon and is found in the System Drawer. For more info refer to the CrossDos manual. Graphics files that are not ASCII based move very well. These are usually referred to as Binary files. TIFFS, TGAs, GIFS and PCX are among a few of the better ones. There are both Mac and PC flavors of each of these so be careful. Also, some Macintosh programs, such as Photoshop do not like compressed TIFFS. Another good way to transfer data is through an emulator board such as EMPLANT. The Emlant is an emulator that can currently emulate a full color macintosh at Quadra or near Quadra speeds. Future software modules will be available to allow PC emulation as well as Sega Genesis, Nintendo, Atari St, and more. 23. Will my Bernoulli work with an Emplant? Yes. Iomega makes drivers for the Bernoulli on the Macintosh. You will need these in order for your Bernoulli to work properly with either and Emplant or a real Macintosh. Many people use the Bernoulli 150 as their boot device for the Emplant in hopes that in the future when other emulation modules for the Emplant are released, they will simply put a different boot disk in. The drivers for the Macintosh are available on Iomega's BBS. the BBS number is (801) 392-9819. Look for them in the Macintosh files section. 24. Can I use the Emplant as a SCSI controller card for the Amiga? Some 4000 owners who are short on slots wish to use the Emplant as a SCSI controller for the Amiga side as well as the Macintosh. This is possible, and is improving all the time. Currently, the Emplant will mount the Bernoulli 150 on the Amiga side if you have the program called SCSI Mounter. This program is available on many BBSs and on Iomega's BBS. You will need to use empscsi.device as your device driver. It is located in the Devs drawer if you have installed the Emplant software. Refer to the Emplant manual for more information. 25. Will the Bernoulli work well with the Toaster? Yes. Many people including the Artists at SeaQuest and Babylon V's Foundation Imaging use the Bernoulli 150 every day with the Toaster. It is great for holding framestores, animations, and for storing Toaster Project files. Many people put their animation frames on the Bernoulli 150 then take them to a production house to be layed to video tape. I personally put my animations on them, and take them to a Video Producer that has Amiga's, Bernoulli drives, and a PAR card (Personal Animation Recorder). The images are then brought into the PAR and laid to tape at several different speeds. 26. How can I save PAR files in their compressed Anim format directly to Bernoulli? This is a very important question. Since the PAR can litterally take 300 Frames at approximately 1 Meg each and put them in an Anim format that can take as little as 5 Megabytes, it would be nice to save the smaller files away. The PAR uses an IDE drive that has a device name of DDR. if you go to a CLI shell (Command Line Interface) and use the copy command to copy files from DDR: to Bernoulli: then the files will transfer in their stored format. From the command line type: copy DDR:xxxx.xxx B150:xxxxx.xxx where DDR is the device name of the IDE drive, xxxx.xxx is the file name, and B150 is the device name of the Bernoulli. 27. Will the Bernoulli work with the Sunrise Studio 16 Digital Audio Board? Yes. In fact, I have recieved a report from Sunrise that they were able to use 7 of the 8 tracks with their latest version of software. Unlike the Syquest that can only support 3 or 4 tracks at best due to its speed, the Bernoulli 150 was able to use 7 tracks. This will make it very convenient for working on multiple projects without tying up your hard drive or without having to erase your work everytime you switch projects. 28. Can the Bernoulli 150 be accessed via a network? Yes. The Amiga uses primarily peer to peer networking, thus it is simple to mount the Bernoulli as a volume that can be accessible to all the computers on the network. Refer to your networking software manual for instructions. 29. I have an Amiga 3000 and an Amiga 1200. The 1200 has no SCSI. How can I access the Bernoulli 150 from my Amiga 1200? You can access it via a network if you wish. The lowest cost network available is PARNET. PARNET is free. You simply run a special cable from each of your computers parallel ports, and use the PARNET software to access each others hard drives and Bernoulli. The readme files that come with PARNET also explain how to build the cable. PARNET is available on many BBS services. 30. Can I use the Bernoulli as Backup, and what options do I have? Yes. The Bernoulli 150 is a great way to back up your fixed drives. You have several choices for backup methods. The simplest and least expensive method is 'drag and drop'. Simply grab the icons that you want to backup from the hard drive and drag them to the Bernoulli 150. You will now have a duplicate copy of them on the Bernoulli. I personally use this method. While it is not the most convenient nor automatic method, it does allow me to make a duplicate image of my hard drive that is immediately accessible and I can boot from it in the event my hard drive goes down. Commodore includes a backup utility with their operating system. It is called HDBackup. This utility should work fine for backing up. The instructions are in your operating manual. I don't know of many people who use this utility. Two commercial utilities are QuarterBack and AmiBack. Both of this utilities have been reported to work just fine. 31. Can I use either QuarterBack Tools or AmiBack Tools Plus to optimize and to fix data problems on my Bernoulli 150? Yes. Both work well for data recover and for optimization of the Bernoulli 150 Drive. As far as the Amiga is concerned, the Bernoulli acts just like a hard drive. Most programs that work with the hard drive, should work with the Bernie as well. I have used both, and while the QuaterBack 5.0 backup utility seems to be more solid, I have found that AmiBack Tools rescue and optimizer seem to be alot faster. It sure is nice to have both. 32. I deal with printing service bureaus and they don't have a Bernoulli. How can I get my data to them? For a while, Syquest maintained a large share of the print bureau industry, however, in the last year, many of the top quality bureaus have switched to Bernoulli. If your service bureau does not have a Bernoulli, then contact Iomega's Sales department, and they can negotiate a deal with your bureau. Also, if you have the transportable Bernoulli, then you can take your drive, as well as your disks down to the burea with you. 33. Can I use HDToolbox with non-commodore controller cards? Yes. Simply highlight the HDToolbox Icon from the workbench. Pull down the Icons menu and select "Information". This will pull up an information window. One of these windows will be labled ToolTypes. Select the button that says . This will put your cursor into a one line window. Type the following: SCSI_DEVICE_NAME = xxxxxx.device where xxxxx is the name of your scsi device driver. If you have a GVP card, for example, the device driver is 'gvpscsi.device'. For more information either check in your devs directory, or in your SCSI controller manual. 34. How can I access SCSI Mounter from the pull down menu? There are shareware programs available such as tool manger and Tools Daemon that will allow you to customize your pull down menus. Iomega has 'Tools Daemon' on the BBS if you wish to download it. The BBS Number is (801) 392-9819. 35. Can is use cache software with the Bernoulli 150? The easy answer is Yes. However, I have not personally used any cache software on the Amiga. For those who are unfamiliar with cache (pronounced cash) software, it allows you to speed up disk access of storage devices. The newer Amiga operating systems come with a new format utility that will ask you if you wish to use directory cacheing. This should speed up disk access. There are a few commercial utilities available as well. The Bernoulli 150 has a hardware 256K read/write cache built in. This is a very sophisticated, low level cacheing routine that is very smart. It can not only accept data into its temporary buffer, but it reorganizes the data, so that it can move data to the disk in a very optimum fashion. For most operations, this built in cache is sufficient and no other software cacheing is necessary. 36. Why does the my drive report itself as BETA 150? Is it a beta test drive? No, it is not a beta test drive. When Iomega began its Bernoulli line with the 8" 10 meg cartridges, they were referred to as Alpha Drives. When Iomega began production on smaller 5.25" cartridges, these drives were referred to as Beta Drives. If Iomega were to develop a drive with a smaller form factor, these drives will probably be called Gamma Drives. 37. Why does my 150 Megabyte disk format to 143.9 Megabytes? The storage industry counts their megabytes differently than the Amiga does. Don't worry, you haven't been short changed. There really is 150 Megabytes there. Actually there are 155 Megabytes on the disk. 5 Meg are set aside as spare room for reallocation of sectors as they wear out. The storage industry counts by 1000 byte blocks which equal 1Kilobyte. The Amiga sees 1 KB as a 1024 byte block. Thus the discrepency in size. Don't worry, a rose is a rose is a rose. Call it by any other name, it is still a rose. 38. When I change the SCSI ID# of the drive, the computer reflects no change. Why? This is true with the termination switch as well as with the SCSI ID selector. Even though the back of the drive may reflect a change in SCSI ID, the ID number actually will not update until the drive has been powered down, and then back up again. Once the power has been cycled, and the drive is back on line, the computer should reflect a new SCSI ID number for the drive. 39. I attempted to prep and format several disks using GVP's FastPrep utility. Now when I try to read them, only the first one will mount properly. Why? This is a strange thing. First the short answer: because only the first disk contains RDB (Rigid Disk Block) information on it. All the others may have an AmigaDos format, but have no RDB info on them. Long answer: As was explained earlier, the RDB is where the Amiga stores all the pertinent information about accessing and using a particular disk. This information tells the computer what size the disk is, what the partition name is, etc. When FastPrep is used to prep several disks, and the user names all of the disks the same, for some reason, the RDB only gets written to the first disks. The remaining disks will get formatted with AmigaDos, but will have no RDB info on them. You can either use the Manual install to write the RDB info to the disk, or you can reboot the computer after each format of a new disk. What happens is that FastPrep creates a temporary mountlist in RAM using the RDB off of the first disk. Then subsequent disks will piggy back off of the temporary mountlis in RAM, rather than off of their own RDB. If a disk with no RDB is the first disk in the drive after the computer is booted, the computer cannot generate a temporary mountlist. As far as I can tell, this is what is happening. Again, to reiterate the solution, either use Manual install and 'Write' RDB to disk, or reboot the computer with the RDB-less disk in the drive, and proceed through the install again. Rebooting will flush the temporary mountlist in RAM and force FastPrep to recreate a mountlist and write that info to the disk. You may also consider using HDToolBox to format the disk instead. Information on how to use HDToolBox with non-commodore controller cards is listed earlier in this document. 40. Can I Set the Bernoulli vertically on its side? Yes. The Bernoulli drive will work fine on its side or vertically (internal version) in a vertical drive bay. The drive has even been reported to operate upside down. At the computer trade shows, the Bernoulli is often demonstrated strapped to a 'Thumper' device that shakes the drive constantly while it is doing reads and writes. This is to show how durable the Bernoulli drives really are. 41. Will the IDE Bernoulli 150 drive work with the Amiga? Although an IDE model of the Bernoulli 150 has been recently introduced, its compatibility is currently limited to use with IBM PC compatibles only. I have tested it on the Amiga 4000 and have been unsuccessful in writing to the disk. There is also a question concerning compatibility with the SCSI version drives, and wether or not disks will be interchangeable. As more information becomes available or, if the drive can be made compatible, Iomega will probably make an announcement.
