Hi!

512MB is the limit imposed by the Intel 815 chipset
family... Ben Myers

I read that somewhere, but the Deskpro EN's behavior has me wondering
what would happen. It can and does count up the RAM beyond the 512MB
limit.

Maybe one of these days I'll sit down with one of my assembler books
and try to teach myself about assembly language programming and
program disassembly. Then I can see about trying to Advanced BIOS
Diddling (which may end up being the truth!) ...
