com rides again

[Ken Yap <ken@nlc.net.au>]

For who need to boot Etherboot from a .com file, e.g. from Syslinux or
Disk on Chip, I whipped up a quick header program. Extract the following
tar file in etherboot-4.4.4/, then you can say make ne.com.

It will not work in the presence of extended memory managers and that
sort of thing, you need a clean machine in real mode, which is why I
resisted implementing this for a while.

Let me know how it goes. This will be in 4.4.5.
