AFAIK the boot-1024 restriction is a motherboard BIOS restriction.

Technical note: You can boot over a network if you have a capable
network card with a boot BIOS, i.e. you don't need a disk drive on your
local machine.

But that wasn't your question, I'm just pointing out that if you have
the right BIOS you can do anything. IBM writes (for a fee) custom "boot
managers" which are part of the bootup chain and which circumvent
various restrictions in old BIOS's (it's cost effective for a Fortune
500 to use this method instead of replacing all the hardware). IBM gave
a presentation on this at SCOUG's Warp Expo West a few years ago.

Back to your question. I *think* that some Boot Managers (perhaps
AiRBoot or System Commander) can boot above 1024. The motherboard BIOS
boots to the boot manager which is in the lower 1024, and the boot
manager then uses its own disk i/o routines to boot anywhere on your
large disk. I think.
