I tested it in the same pizza style system I was playing with my IO Magic card in. It works, although the 2940U2 BIOS is hidden. Using the magic Adaptec key sequence still gets me into the BIOS, though. I have it verifying the disk media of an LVD disk right now.
I’m pleased to the see LVD cable I purchased earlier this year actually works. My previous actively terminated cable, with a terminator block, did not actually do anything. This presented a problem for Quantum Atlas SCSI drives, which do not have a jumper block to enable ‘term power on drive’ and do not support the feature. As a result, an actively terminated cable is mandatory.
I also resurrected my IO Magic card. Apparently my 30GB Quantum simply sucks. I can use both ATA ports independently with a single drive dangling (in this case in every sense of the word) off each port. I’ll slip this card away somewhere until I have need of it.
As to the 2940U2, I’m not sure I feel like taking my workstation offline again so I can try to get it working. It really does not like my K7S5A mainboard. Perhaps I’ll wait until Monday or Tuesday when my other two 2940U2(B|W)? cards arrive.
