-
- HINTS AND TIPS
-
- - Nonbootable version may be a little bit faster than the bootable
- version if a fast memory exist in the system ($C00000 may not a real
- fast memory..).
- - Do not use bootable version in A500/A2000 which have 1MB chip memory,
- due to clearing beyond of the first 512KB chip memory after reset.
- - Sometimes after mount command the device handler will be not
- activated. You may use DiskChange command.
- - 'Avail flush' command removes the device from memory if it is
- available.
- - 'Assign FS0: dismount' command is available.
