2.4.28, 64GB highmem, keyboard conflict on Tyan MB

[James D. Freels]

I have two dual-processor Xeon machines set up in a similar manner.
Both have 4GB of main memory.  Machine A utilizes an Intel MB.  In order
to take advantage of all the memory, the 64GB highmem option must be
selected.  If I select only the 4GB option, not quite all of the memory
is used.  Everything works fine on this machine.

Machine B utilizes a Tyan MB.  If I select the 4GB highmem option,
everything works fine except not all the memory is available (only
3616824K shows from "top").  Now if I try to select the 64GB highmem
option similar to Machine A (after recompiling the kernel and trying to
boot), the machine will not boot and the error message displayed to the
console says "missing keyboard".

I have a true ps/2 keyboard on both machines as well as ps/2 mouse.

How can I correct this problem ?  Will I need to change to a USB
keyboard/mouse for this MB ?

I have no idea. But I can suggest, that in order to get meaningful
hints, you may want to mention exactly what kind of motherboards (and
bios levels) you're talking about, along with the top 50 lines of dmesg
output from both the 4 Gb and the 64 Gb kernel on the Tyan MB.

Nobody will know that 'a Tyan MB' is, unless it's the Illuminati and
you wouldn't want those on to you, right?
