HELPFUL HINTS FOR OWNERS OF ONE-DRIVE AMIGA SYSTEMS: By Joel Halbert, CCCC Amiga SIG Using the Amiga with only the standard internal drive can sometimes be a headache, with all of the disk swapping you have to do. This article is intended to help you maximize your efficiency and enjoyment when using only a single drive, especially when using the CLI. Subjects covered in this article: 1) Setting up/using the RAM disk. 2) Specifying disk names to minimize AmigaDOS confusion. 3) Helping you decide which to buy first - another disk/extra RAM? * * SETTING UP AND USING THE RAM DISK * * How the RAMdisk helps to reduce the amount of disk access: The Amiga contains a software "device" in RAM (memory), which can act like another disk drive. The advantages are: a) Less disk swapping. You can copy your most frequently used CLI commands to the RAMdisk. This will greatly reduce the number of "System Requests" where the Amiga asks you to insert the Workbench disk. b) The RAMdisk operates much faster than the floppy drives. c) It uses no moving parts and thus doesn't wear out the disk drives. The disadvantages of RAMdisk are: a) It loses its memory when the power goes off, so you have to remember to copy any new files back onto a real disk before you quit. b) It uses up some free memory in the system - this can be a significant problem if you have not purchased extra RAM. Here are the CLI commands you need to type (either upper or lower case): MAKEDIR RAM:C (creates a :C directory on RAMDisk) COPY WORKBENCH:C RAM:C ALL (copies the entire command directory to the RAMdisk) ASSIGN C: RAM:C (Tells the system to look in the RAMdisk to find the commands, instead of the Workbench disk) You now have all the CLI commands in the RAMdisk, and you will see a dramatic reduction in disk accesses when using the CLI (also takes care of a few of the Intuition icon-type operations). Alternatively, you can conserve RAM space by loading only the commands you think you'll need. There are many ways to accomplish this, but the following method is easiest to explain: a. With the Workbench disk in the drive, issue the CLI commands: MAKEDIR WORKBENCH:QUICKRAM COPY WORKBENCH:C WORKBENCH:QUICKRAM ALL CD WORKBENCH:QUICKRAM DELETE command1 command2 command3 .. DELETE command4 command5 command6 ... and so on, where "command1 command2..." are names of CLI commands that you DON'T think you'll be using. b. Now, whenever you want to set up the RAMdisk, issue the commands: MAKEDIR RAM:C COPY WORKBENCH:QUICKRAM RAM:QUICKRAM ALL ASSIGN C: RAM:QUICKRAM These are the same commands we talked about before, but you are using the new :QUICKRAM directory to load in only the commands you want. If you want to clear out the RAMdisk and reclaim the memory, type: ASSIGN C: WORKBENCH:C followed by either: DELETE RAM:C ALL or: DELETE RAM:QUICKRAM ALL depending on which directory you created in RAM. A final note: once you understand how to use command sequence files and the CLI "Execute" command, you can reduce the amount of typing by having the computer issue all of the commands for you. * * SPECIFYING DISK NAMES * * Some users have asked why they can't seem to get a directory of any disk other than the Workbench. The symptoms are: You have disk (let's say it's your Extras disk) in the drive. You type "DIR" and the system requests that you insert the Workbench disk. When you do that, you get the directory of the Workbench disk! What is the problem here? First of all, the Amiga needed your Workbench disk in order to interpret and carry out the DIR command. Secondly, you forgot to specify the disk name as part of the DIR command, so the system assumed the default, which was the Workbench disk (the one you booted up with). If you want the directory of the the Extras disk, you must specify it explicitly: DIR Extras: There is a lot more that can be said about disk names, but you'll find that in the AmigaDOS Manual and in the other tutorials that we are publishing. * * WHICH TO BUY FIRST - ANOTHER DISK * * * * DRIVE OR ADDITIONAL RAM MEMORY? * * Well, both of these add-ons are going to make your Amiga much easier and more pleasant to use. More RAM allows you to run more programs simultaneously, and some programs are too big to fit into the 256K that comes standard. Another disk drive will greatly reduce the amount of disk swapping that you have to do, and it makes copying from one disk to another infinitely easier. You have to decide which is most important to you, but it is USUALLY BEST TO BUY THE EXTRA RAM FIRST. This is because the system uses some of the RAM just to manage disk drive operations. If you add another disk without adding more RAM, you are effectively DECREASING the amount of RAM that is available to you for program and file storage.
