[syslinux] pxelinux localboot

[kkobb at att.net]

I tried playing with the BIOS settings and a couple of 
other things, and it still locked up. I haven't had a 
chance to try a different system/NIC yet.

I did find a way to get a localboot though. Made a 
floppy image with a copy of Smart Boot Manager on it. 
Set it to boot first hard drive, and set timeout to 0 
seconds. Select this image, and localboot works. Not 
very elegant, but for now if I need to, I can.

Thanks again.
