How to allocate about 64K bytes base memory

[Feng Shuo]

I’m still working on UNDI now :(
Most PXE UNDI APIs need 32K-64K bytes base memory to work. Where can I
allocate them safely?
I have tried to do this at the high end of the base memory, at the low
end, and at the 512K-576K (the end of the grub used memory). ----None of
them seems work well with grub in loading kernel or disk I/O :(

BTW. Dose grub need to work with interrupt enable or disable?
