Newbie install problems...

[Robert Cardell <rbt_(_at_)_mtlb_(_dot_)_co_(_dot_)_uk>]

Hi all,

I've just got my OpenBSD 2.5 CD, and I'm having trouble using it after
installation. I'm new to OpenBSD, or BSD in general (I've got a few
years' Linux under my belt, so I'm not completely clueless). I've tried
this on two different machines, and got two very different problems,
described below.

In both cases,
- I let OpenBSD have the entire first hard disk.

- OpenBSD was installed via NFS from a Linux box.

- I followed the install instructions in the CD inlay pretty much to the
letter.

- I installed all the packages


Machine A:

Config: VL-Bus AMD 486DX2-66 CPU
        16MB memory
        2MB Diamond Stealth Pro ISA video card (S3 928)
        NE2000-compatible network card (0x300, IRQ 10)
        Adaptec AHA-1542CF @ 0x330, IRQ 11
           SCSI ID 0 : Micropolis 4110 (1GB)
                ID 1 : DEC 5220 (2GB)

Install goes smoothly, but at reboot, I just get a message saying 
"Using Drive: 0 Partition: 3" at the top of the screen. I've tried this
install with and without the Adaptec Large Disk support option, and I
can't figure out what else the problem could be. Ideas, anyone?


Machine B:

Config: VL-Bus AMD 5x86-160MHz
        128MB Memory
        4MB STB Velocity 64 VLB video card (S3 968)
        NE2000-compatible network card (0x300, IRQ 10)
        Buslogic BT-445C @ 0x130
            Plextor PX-32TSi CD-ROM drive (ID 3)
        Gravis Ultrasound MAX (1MB) @ 0x220
        Seagate ST32140A IDE hard drive

This one actually boots after install, but stops in the process at what
I assume is some kind of in-kernel debugger. Here's what's on my screen
when it stops (hope I haven't made any typos:)

My guess is it's having problems allocating a DMA buffer for the
Ultrasound. Is there a way to have it ignore the GUS without physically
removing it? or is the problem something else?
