Ok, so you likely do not have a problem with a 32-bit host (HD images
could be limited to 2 or 4 GB there).

Ok, I just wanted to make sure that you do not use TOS 1.00 or 1.02 ..
these are likely to fail with big hard disk images.

Ok, would 1 GB be sufficient? If yes, I'd recommend starting with that
size. I doubt that AHDI can handle bigger partitions, since the initial
ACSI bus specification had a limit to that size with the addressing
mode.
There were some extensions to the ACSI protocol done by ICD which
allowed bigger drives, but you need a compatible hard disk driver for
supporting these. HDDriver should be fine, but I think you need to
enable the ICD extensions there first.
