There have been several questions lately about how to get programs that
expect df1: to work when used with an A2000 (which has df0: and df2:, but no
df1:.) I had a similar problem with my old A1000 single drive system before
I upgraded to the A2000. I discovered with the aid of the net (either this
one or FidoNet) that if you DON'T have a device df1:, you can ASSIGN df1: to
any valid directory. In this case, most programs will NOT know the difference.
I used this trick to make disksalv work to a directory on my RAM: device. (I
had 2.5 Meg of RAM.) I don't have any IBM stuff, so I can't try it, but it
may work in that case also. Try it and let us know if it works for you, BUT
as always, make backups FIRST!!!
I hope that this helps,
Jim Pritchett

If there is an entry in devs/mountlist that has the name DF1: but unit=2 and you say "MOUNT DF1:", then all references to DF1: will go to the external floppy. (This is easier than changing the jumper on the motherboard that says DF1 is external.) The mountlist for AmigaDOS 1.3 is already set up - just add the MOUNT command to your startup-sequence. For AmigaDOS 1.2, just take the existing mountlist, remove the "/*" before DF1 and "*/" after the "#", change UNIT= to 2, and change HIGHCYL= to 9. -- +----------------------------------------------------------------------------+ | TYMNET:JMS@F29 CA:"POPJ P," UUCP:{ames|pyramid}oliveb!tymix!antares!jms | | INTERNET: (Office-1.ARPA is no more) PHONE:Joe Smith @ (408)922-6220 | +----------------------------------------------------------------------------+

I used the DF1: mountlist entry provided in 1.3. It had several
interesting side effects. For one, if you took out a disk out of the
external drive, optionally replacing another disk, only df1: would know
about it, df2 would still think it was there. You can verify this with
the info command. If you then tried to reference df2: you would get a
requestor. Repeating this a number of times would sometimes cause a
system crash. I stopped mounting df1: for this reason. It appears to
me that having two different devices go to the same physical unit can
cause problems. Can someone else try this and verify this?
