aha0 targ 0 lun 0: <unknownunknowngarbage> SCSI0 direct fixed
sd0 at scsibus0sd0: mode sense (4) returned nonsense; using ficticious geometry

My system information is as follows:

Gateway 2000 486DX2/66 PCI w/ 16 megs of RAM
Diamond Viper PCI video card w/ 2 megs VRAM
Adaptec 1542C scsi controller
Seagate ST3600N scsi HD
Toshiba XM3501B external quad-spin scsi cd-rom drive
SB AWE32
Colorado Memory Systems Jumbo 250 tape backup
U.S. Robotics 28.8 internal modem
3Com 3C509 ethernet card

I am using the correct install disk (kcaha) which supposedly has the Adaptec
drivers necessary for my system.  My controller is set at the proper address
of 0x330.  I originally thought it might be a problem with the boot sector of
my HD, so I low-level formatted it, and the problem still persists.  I already

me.  If any of you have ideas, I would greatly appreciate them.  Thank you.

Well, I have a very similar setup to yours sitting on my desk at work
and i got the same problem. The first thing I did was try a -current
kernel, which got past the initial mode sense error, and got all the
way to the "mounting sd0a" when it failed (panics). This might be a
function of a slightly crufty HD, so I'd suggest you try booting with
a -current kernel, and if it works for you.. could you tell me?
