I won't argue with that, it is at least 15 years old..

No, it was using E801:
BIOS-provided physical RAM map:
BIOS-e801: 0000000000000000 - 000000000009f000 (usable)
BIOS-e801: 0000000000100000 - 0000000010000000 (usable)
The new kernel has the '1' in the top end of the second
part being one place to the right:
BIOS-provided physical RAM map:
BIOS-e801: 0000000000000000 - 000000000009f000 (usable)
BIOS-e801: 0000000000100000 - 0000000001000000 (usable)

I suspect not, given it's not using E820. But could be wrong. ;-)

Would be happy to try with some instructions if it would help.
