Folks, as usual with IBM, we are left with suspicions and suggestive passages. This morning, I fed my Brittanies around 0510, brewed up a pot of French Press coffee. Then the utterances of Saint Katherine of Rohl came to me, unbidden. The Corvette lacks a SCSI BIOS and the SCSI firmware has a "stub". What this stub does, or what procedure it calls, or what address it points to, I dunno. Since the Corvette is an RS/6000 adapter, there is no announcement letter for it, instead, it is part of a system announcement letter, fer instance, for the 580. The POWER2 systems seem to be the first ones to support the Corvette's need for the SCSI BIOS internalized in IML code. If we look at the "Enhanced Complex BIOS" or "Dual Boot" upgrade complex BIOS for the T1 -AND- T2, both are from Mar '92. The upgrade needs the T1 ver 1.31 refdisk or the T2 ver 1.21 refdisk are both from Nov '92. The RETAIN tip about the Corvette in a 8595 says there are improvements in SCSI stuff, but no mention of the F/W. The earliest POWER2 systems that offered the F/W are in mid-'94. But that doesn't mean the Corvette couldn't be ordered separately from the system. RPQ or special bid... My SWAG is the Korvetten-class were under development in '92, and IBM most likely planned for introduction on the high-end 90/95 and on POWER2 and better RS/6000. Another thought, offering a high-end SCSI adapter that requires an upper-end product seems like pure IBM marketing.
