I enabled it, but it appears to not support it. The drive is a couple of
years old; possibly before its time.. Is this what the Sun drives use to
configure IDs automatically?

I now get term power from all drives. There doesn't seem to be that
option on my Tosh 5701 internal CDROM, though. It just says 'Power' and I
left it jumpered.
Active terminators? External and internal? Apparently you only have one
of the two chains used internally? Active termination simply refers to
the drive providing termination via actual resistors, correct? Passive
would be provided by the controller only, right?
If it makes a difference at this point, I did start from a clean 2.0.30
before patching with pre3.
Thanks a million. Can we blame this on a better implementation of the
specs from Adaptec that caused this? Nice job, guys.
