Maybe I'm simply lost or stupid.? You're doing a fresh install, or what ? How's your disk layout ? (And, as Nick pointed out, does it boot from diskette / CD ?) http://www.openbsd.org/faq/faq8.html#Bootloader http://www.openbsd.org/faq/faq14.html#Boot386 scroll down to What can go wrong and understand how to recreate the MBR. HTH, Uwe, who runs a 160GB hard disk without any hassle on a 1995 P100 MB with a limit of 8GB hard disk; and a root partition of 150 MB at 'a'. With the completely wrong geometry. I guess, as long as the '/' is found somehow, the rest is taken over from the BIOS.

It didn't even manage to load the MBR boot loader. Previously, you got the MBR, the partition boot record (PBR), and /boot loaded, it died loading the kernel. That's consistant with having zeroed the MBR (though since you didn't say HOW you did it, I'm not going to say anything is "final" there), but didn't properly restore it (and since you didn't indicate how you did that, I think that's a very safe bet). Let's step back a bit here. If you boot from the CDROM (or floppy), you get to a cdrom> or boot> prompt. What happens if you, at that prompt, tell it boot hd0a:/bsd If it boots properly there, that means your boot code is hosed. Well, actually, I'm convinced your boot code is hosed, it would be nice to see something actually working, though, right? If using the boot floppy or CD that way DOESN'T work, you have multiple problems. Nick.
Re: Problem booting from wd0
Thanks for all the suggestions. It appears to be a
problem with disk block mapping even though LBA mode
is used. In light of the suggestions, this is what I
did today:
Use dd form /dev/zero to wipe MBR and start of disk.
Check Bios settings - AMI Bios set to "Auto" shows
LBA mode and DMA, etc.
Downloaded June 10 snapshot and checked md5 sums.
Installed without problems. The installboot output
was:
boot: /mnt/boot
proto: /usr/mdec/biosboot
device: /dev/rwd0c
/usr/mdec/biosboot: entry point 0 proto bootblock
size 512
/mnt/boot is 3 blocks x 16384 bytes fs block shift 2;
part offset 63; inode block 24, offset 1704
using MBR partition 0: type 166 (0xa6) offset 63 (0x3f)
When I attempted to reboot from disk, the system hung at:
Searching for Boot Record from IDE-0..OK
The dmesg from the CD boot is:

That's too early in the boot process for a simple compatability problem...that message indicates the kernel didn't load properly...it wasn't even trying to be executed at that point. Either a kernel in mid-upgrade on the FTP servers, or a kernel (and possibly *.tgz?) from a wrong platform (yeah, I've done that), a kernel downloaded to a Windows machine using the (default) ASCII transfer mode or something similar. I suppose a bad spot on the hard disk could cause that, too... In short: be thinking something really basic is wrong. Nick.
Problem booting from wd0
I am trying to install 3.7 on a cheap PC.
The system boots fine from the CD and installs
without problems. However, when I try to reboot
from disk, I only get:
booting hd0a:/bsd: 4729760read text: Invalid argument
failed(22). will try /obsd
I am trying to use a recent snapshot; here is the
dmesg from a CD boot:
