OK, I can see that. Here are the SCSI-detect lines from the (working)
2.2.19 boot sequence:

(scsi1) <Adaptec AIC-7899 Ultra 160/m SCSI host adapter> found at PCI 2/1/1

If I read them correctly, this would appear to indicate that the hard
drives are attached to the B channel, right? And 2.4.5 only appears to
be detecting the A channel (which is being run to an external port).
I guess the next question, then, is why isn't the second channel being
detected by 2.4.5? And what needs to be done to get both channels
detected?
