Extended memory manager? You still have DOS on the brain, Jeff. 32-bit
code has no problem accessing memory beyond 1 MB.

gzip compressed images don't make more memory available, so they don't
overcome the 640kB memory limitation per se. To load above the 1 MB mark
you need bzImages. Note: many people think the b stands for bzip. It
doesn't. It stands for big.
