5.3 Loader Too Fragile

Can someone help me build a hardwired version of the loader that will
let me boot my system?

System is a 440LX dual CPU DEC Personal Workstation Station 333i+.
There are no IDE devices. CD and HD are SCSI on 2940U2W controller.
I saw in the code that this is bad news if guessing is required.

Couldn't boot from floppy or CDROM, I couldn't even get them to take
any of numerous variations of switching console from vidconsole to
comconsole to capture error messages, so I built hard drive on another
system. I get:

BTX loader 1.00 BTX version is 1.01
Console: internal video/keyboard
BIOS drive A: is disk0
BIOS drive C: is disk1
BIOS 509kB/130048kB available memory

FreeBSD/i386 bootstrap loader, Revision 1.1
(root at harlow.cse.buffalo.edu, Thu Nov  4 22:29:29 UTC 2004)
Loading /boot/defaults/loader.conf
/boot/kernel/kernel text=0x22c3e0 Console: internal video/keyboard
BIOS drive A: is disk0
BIOS drive C: is disk1
BIOS 509kB/130048kB available memory

FreeBSD/i386 bootstrap loader, Revision 1.1
(root at harlow.cse.buffalo.edu, Thu Nov  4 22:29:29 UTC 2004)
Can't work out which disk we are booting from.
Guessed BIOS device 0xffffffff not found by probes defaulting to disk0:

panic: free: guard1 fail @ 0x517c4 from [line folded for mail]
 /usr/src/sys/boot/i386/loader/../../common/module.c:957
--> Press a key on the console to reboot <--

I had similar problems with 5.2.1 but was able to resolve them by upgrading
to March 25th 5-Current, so I am reasonably sure the hardware is in good
shape.

Thanks,
