What do the two different rams disk settings do? I heard some time ago that
if they were not the same, that the ram disk could screw up and crash the
computer. Is this (still) true?
Thanks!

Yes, in fact as I recall the ROM03 IIGS doesn't provide the ability to set them independently.

The 'minimum' setting controls how much memory is initially allocated for the RAMdisk. The 'maximum' setting is the most memory it will allocate. The problem here is that when a program tries to write to the RAMdisk and the RAMdisk can't allocate more memory, it returns an I/O Error -- this can be really annoying and I always set my RAMdisk to the same min/max settings in order to avoid it. (Solution: get a hard drive and don't use the ramdisk!) Apple (amazingly) figured this out and fixed it in the ROM 03 by changing the ramdisk option so that it has one size setting and always allocates the entire disk beforehand.
