I've just been looking at a Slackware CD, and I was wondering if you 
actually needed to be running Linux to be able to build your own kernel...

It looks to me as though this kernel building is done using shell scripts.
If that is the case, then should I be able to a build the correct kernel 
under an appropriate SHELL on any other OS, including OS/2?

I've seen output from pxelinux on the client screen but have problems due 
to a missing 'tsize' option on my TFTP Server, so I may not be able to get 
much further just at the moment, at least with pxelinux. I have got 
further using bpbatch, though. I did manage to get OS/2 to boot from the 
client's local hard disk using bpbatch commands.

I want to be able to boot a wide variety of OS's on a network computer 
without having to install them. I'm also interested in developing my 
knowledge of DHCP/PXE.
