I don't think so: the info comes straight from Adaptec tech support, so your PROMs are probably not of the early ones, or you changed them. The adapter simply can't use disks >1 GB with the early PROMs, it's not a matter of OS, it only accesses the first GB. We had occasion to perform these PROM changes, and see the full size of the disks appear where it did not appear earlier.. By the way, we are talking GB of size 1 073 741 824, not 1 000 000. Are you sure this is not what you actually get from your 1.2 GB drive ? Accordingly, Adaptec tech support MIGHT know less about its own products than you do, so you might be right. Stranger things have been said to happen.
