- OKAY, I just got done dealing with this myself a week ago, and there was lots
- of misinformation on the net earlier, so let's clear this one up for good.
- From the top:
-
- Prodos 8 was originally designed to expect only two disks/drives/partitions
- in each slot. To get around this and let you use all your partitions anyway,
- the Ramfast firmware (versions 1.x, and 2.x -- which you have) manually tells
- Prodos 8 about them.
-
- However, when Prodos 2.0 was introduced with system 6.0, Apple made it smart
- enough to figure out that there were extra partitions. Now we have both Prodos
- and the Ramfast activating the extra partitions, and all kinds of weird things
- begin to happen -- for instance, I kept getting two copies of /RAM as well as
- every partition. Unmapping partitions except for the boot partition DOES NOT
- WORK, even though some people on the net were claiming that it does.
-
- THE ONLY SOLUTIONS THAT WORK ARE TO EITHER GET RAMFAST ROM 3.0 OR REBOOT INTO
- PRE-2.0 PRODOS 8 TO RUN PRODOS 8 PROGRAMS.
-
- Ramfast ROM 3.0 uses a much better remapping technique. If you don't map
- anything outside the ramfast slot, it lets Prodos do everything the way Apple
- expected it to work. If you *do* map stuff outside the ramfast slot, then
- the ramfast lies to prodos and says it only has the partitions in its slot,
- and manually pokes the rest.
