i386 memory size problems

processor, and it runs a proprietary Compaq bios (it simply says "Compaq
Deskpro 2000").
The machine has 64 mb ram (4 x 16 mb EDO), at least the bios, my eyes
and the stickers on the chips say so. But OpenBSD only sees 16 MB. Also,
the `machine extmem' command in BOOT doesn't seem to work.
I am running the 2.6 GENERIC kernel compiled by theo. I have attached a
dmesg of said machine.

I've a Compaq DeskPro 590 that does the same thing. It's a Pentium
90, used as a dial-in server for an Alpha 8200. It has 96MB of RAM
physically, and that is detected and used properly by NetBSD and
Linux, but OpenBSD sees only 16MB.
I've tried compiling a kernel with the EXTMEMSIZE (I think) set to
95MB, 63MB, 31MB and other (16n - 1) memory sizes, but they all
fail to boot. Additionally, setting memsize in the boot loader
won't work, either. It seems we have the same problem. At least
I'm not totally crazy.

I, too, have reverted to the 2.6 GENERIC kernel. It seems stable
enough, but the memory issue keeps me from applying the proper
security patches (i.e. user-can-ifconfig, etc.) and recompiling the
system.
The dmesg output for this machine follows.

Me TOO!
Mine is a Compaq Prosignia VS (486/66/EISA). Same problem,
32M physical, only 16M is seen. It used to run Linux, and
had the same problem in the beginning, but at some point
Linux started seeing all of the memory (sorry, cannot
remember the details...)

I hope someone else has been flollowing this thread besides me, and the
fact that it has popped up quite a few times in the past month. This is
not an isolated case, and the common denominator seems to be that its
compaq? Most likely with either a proprietary custom bios, or a
"diagnostics partition". For a test I recompiled the generic kernel
with EXTMEM_SIZE=32 (the amount specified by the bios on bootup) And
the kernel failed to boot with a message of "Memory size too small,
running in degraded mode" or something of the like. The bootloader
only reports 16M as well.
As far as i have read (Im not proficient with C or OS internals), the
boot loader goes through the ram one page at a time until it fails. So
would this mean that a bios option like "Memory hold at 16M" set to yes
could cause the problem? I dont think compaq bioses have this option,
at least mine doesnt.
I would be most appreciative if anyone with knowledge of this could help
out. This seems to be plauging quite a few people. I am willing to
test any patches or changes that could provide a fix.

Various people seem to be having memory sizing problems on compaq machines.
Unfortunately, I do not have access to a compaq machine to do further testing
and fixing of this. However, the first check I'd do, is go through your BIOS
options, and check for a 'extended memory reporting' option. I know for a
fact, that if that sort of option is set to 'OS2 reporting mode', things will
find a maximum of 16MB of RAM. Switching it to 'non-OS2' mode should make
things work most of the time.
Having said that, if somebody can point me at a spec for the OS2 version of
the 'get extended memory call' BIOS function, I'll about adding support for
it to the bootblocks.

a prosignia 500. I also found that if you upgrade the bios the system
will not boot. You can install Linux fine but it will not boot.
Windows will work fine. I think it is a compaq thing.
