There is definitely something strange happening. The image I used to
do the (nearly) complete install will no longer configure the network.
Very inconsistent. I will try it (same image) again later today and
see if it "just works" next time - like it did last time.

Can't jump to console 2 - I can only comunicate through the serial
console. However I'll give this a shot through the "execute shell"
menu item. "set 1 prep on"? Haven't seen that documented anywhere,
what does it do?

I' have the partition ready ...

Unfortunately, until the network comes back up, I can't get far enough
in the install to access the SCSI drives (is there another way? Load
the modules by hand? Which ones?). Without this, I can't get at the
image I need to boot in order to get it onto the right partition. I
also can't get it to another machine to net boot it.

Actually /dev/sdbX doesn't exist at all during the install from what I
have seen. The drives are refered to as
/dev/scsi/host0/etc/.../etc/part1. I have two drives, one is 9 Gig
with scsi id (0,4,0) (/dev/sda) . This is blank except for a 10 Meg
boot partition; type 41. The second drive is 20 Gig with scsi id
(0,5,0)(/dev/sdb) which is where the install is.

I copied (with dd) the file (the wrong file I suspect) to
/dev/scsi/...../part1 which should correspond to the first partiton on
the 9 Gig drive.

I see how much more time I can buy with this machine. It may need to
go back into storage this week if I can't make it run. Not fun.

Thanks for everyone's help.
