CMD CQD-220 ROM fixes

Updating the firmware to the B3A2 revision seems to have done the trick. I'm now running through my second install (my CD is reporting fatally bad blocks, so it's a good thing I imaged it when I got it) and everything seems fairly happy aside from the disc errors. As far as I know, bumping to A8 might have fixed it, but given the relatively long and interactive process that testing several revisions would take, I thought I might go for the gold. For those wondering: B3A2 seems to work very nicely, and has vastly improved the online utility (the one reachable through either executable code or the serial port). It even seems to have added improved SCSI clustering support, if anyone was interested in that. And it even feels a bit snappier, though that's totally subjective and possibly all in my head.
