First, thanks for your reply.
My complaint about fragility was actually directed at the Loader's
inability to usefully indicate what it was unable to deal with. I
realize that there is precious little code space for elaborate error
messages, but it's inability to keep the console directed at the
serial port, thus preventing capture of the error messages that were
generated, seemed worthy of attention.

Yet no so braindead that FreeBSD 4.10 fails to find it serviceable.

They're exactly the same numbers reported for memory when booting
FreeBSD 4.10. There is one stick of 128MB memory on the system.

Pretty much any other 440LX based mother board would be around the
same age. There is no indication that the 440LX chipset has been
deliberately desupported. The fact that DEC was acquired, twofold,
also seems irrelevant as HP has the same level of support, i.e., old
BIOS files and manuals available on their web site, that can be found
for 440LX based motherboards whose manufacturer has managed keep the
same name.
The machine is quite functional with respect to FreeBSD 4.10 and ran
March 25th 5-Current fine as well. I was unfortunately over optimistic
and wrote over that installation but hope to recover to that state.
I guess I'll have to embark on a binary search to find what lines of
code raised the BIOS requirements for FreeBSD 5.
Here is the serial console capture for a FreeBSD 4.10 boot:
Console: serial port
BIOS drive A: is disk0
BIOS drive C: is disk1
BIOS 509kB/130048kB available memory
