memory below 1MB... important?

[Jeff]

Hey everybody,

Originally I was planning on having two separate
memory allocation routines. One for allocated
withen the first MB, and the other for all memory
above the first MB.

Is this necessary? Or should I forget about
differentiating between these two memory areas
and just develop one allocation routine?

Thanks a ton,
Jeff

I say don't worry about the little bits of mem in between
ROMS.
Of course you need to save the real mode IDT, but what I
plan on doing is to reserve the memory below 1meg for DMA
transfers.
