Hello:

Out of curiousity, I decided to peruse the scsi(8) manpage, and when
I tried to run one of the examples, this is what I found:

% scsi -f /dev/rsd0c -c "12 0 0 0 64 0" -i 64 "s8 z8 z16 z4"

SCIOCCOMMAND ioctl: Command accepted.
 host adapter status 2
Command out (6 of 6):
12 00 00 00 64 00 

Data in (64 of 64):

I am still not sure why the boot code cannot INQUIRE to my disks:

% dmesg | grep aic

aic0 at 0x340-0x35f irq 11 on isa
aic0 waiting for scsi devices to settle
(aic0:1:0): "CDC 94171-9 0045" type 0 fixed SCSI 1
sd0(aic0:1:0): Direct-Access 312MB (640584 512 byte sectors)
(aic0:2:0): "unknown unknown ????" type 0 fixed SCSI 0
sd1(aic0:2:0): Direct-Access 312MB (640500 512 byte sectors)

So, scsi(8) works, but the driver is not talking to one of my drives
properly.
