For the record, the line or two about drives is *NOT* the problem that I was
mentioning originally. I was refering more to this:

aic7xxx: Chip reset not cleared; clearing manually.
aic7xxx: Extended translation disabled.
aic7xxx: AHA-2740 Rev C and previous.
aic7xxx: Using 4 SCB's; No SCB memory check.
aic7xxx: Using level sensitive interrupts.
aic7xxx: Enabled channel B of AHA-2740-Twin.
AHA-2740-TWIN AT EISA SLOT 1:
irq 14
bus release time 60 bclks
data fifo threshold 100
SCSI CHANNEL A:
scsi id 7
scsi selection timeout 256 ms
scsi bus reset at power-on enabled
scsi bus parity enabled
scsi bus termination (low byte) enabled
aic7xxx: Downloading sequencer code...done.
aic7xxx: Resetting the SCSI bus...done.
scsi0 : Adaptec AHA274x/284x/294x (EISA/VLB/PCI-Fast SCSI) 2.22/2.2/2.8
scsi : 1 host.
aic7xxx: Scanning channel A for devices.
aic7xxx: Target 0, channel A, now synchronous at 10.0MHz, offset(0xf).
Vendor: MICROP Model: 1548-15MZ1077810 Rev: HZ2P
Type: Direct-Access ANSI SCSI revision: 01 CCS
Detected scsi disk sda at scsi0, channel 0, id 0, lun 0
aic7xxx: Target 6, channel A, now synchronous at 4.0MHz, offset(0xf).
Vendor: TOSHIBA Model: CD-ROM XM-3401TA Rev: 2873
Type: CD-ROM ANSI SCSI revision: 02
Detected scsi CD-ROM sr0 at scsi0, channel 0, id 6, lun 0
aic7xxx: Scanning channel B for devices.
scsi : detected 1 SCSI cdrom 1 SCSI disk total.
SCSI Hardware sector size is 512 bytes on device sda


I think that this is excessive.

Mike was here...
