I was told the maximum size of under 1GIG was all the A2091in standard state could use. The upgraded 7.0 rom/s will then be easier on compatibility then? How big a SCSI HDD can I use with this upgrade of the A2091?I have seen upgrades for the accelerator card would I salso need these if I keep the 2.04? rom in my A2000? If I upgrade the rom to 3.1 I've been advised I would have to upgrade the roms on the accelerator card to the latest version.I presume this is correct?
