Frequently Reported Problems

This copy of Professional File System II is invalid

This message appears if an unregistered PFS2 is started. PFS2 is registered by installing it using the install script on the CD. Directly copying the filesystem from the CD to the RDB does not work and will result in this error message.

If you have this problem you have to replace the old filesystem you used on the partition in order to make it functional again. Please follow the following steps to achieve this:
 

• Insert the Workbench Install disk or any other bootable Workbench disk in df0:
• Restart the computer while holding both mouse buttons. The boot menu will appear.
• Disable all affected partitions in the bootmenu
• Continue and wait while the system boots from the Workbench disk
• Start HDToolbox from the Workbench Install disk. It can be found in the HDTools drawer.
• Reinstall your previously used filesystem. FFS can be found on the Workbench floppy, AFS on your AFS floppy.
• Reboot
• Install PFS2 by double-clicking the Install icon. The install program will register PFS2 and place it in the L: directory.
• Start HDToolbox and install PFS2 on the RDB. See the manual for details.

PFS2  doesn't work on my 4GB+ harddisk

The standard PFS2 version can only access the lower 4GB of the harddisk. To access the area above 4GB the direct scsi version, which has been specially designed for this purpose, has to be installed.

This is probably caused by a wrong DMA mask setting. In PFS2 the DMA mask is much better checked then AFS did, providing better compatibility with old devices. Downside is that the mask should be set more securely. The mask should be set as large as possible without causing problems. For Zorro II devices on a Zorro III machine, a setting of 0xfffffc (6 figures, see note) is save for almost all devices. Some devices allow larger masks, and if they do, you should make use of it! If you don't, you'll wind up using valuable and slow Chip RAM. Check your driver documentation if you're not sure.

Note: in the German manual the value '0xffffc' is suggested for the Mask on Zorro II machines. This is wrong. The right value to use is '0xfffffc'.
 

• 0121.  The normal (none direct-scsi) version doesn't check for the 4G bound when accessing the device, causing it to access other areas. 
  
  
• 0122.  The German manual states a wrong DMA mask for Zorro II devices. The correct setting is 0xfffffc (5 times 'f', followed by one 'c').
