Syslinux - Apr 2003 - [pxelinux] fix for Realtek PXE implementation

I found (and fixed) a problem with my realtek onboard 8139 controller.
dhcpd server sends filename "pxelinux.0" but realtek requests
"pxelinux.0\377"
(i.e. the octal character 377 is appended), resulting in a file not found
during
the tftpd phase.

I fixed this by adding a mapping to tftpd:

# strip ending garbage from filenames (Realtek PXE bug)
r ^([[:graph:]]*)(.+)$ \1

maybe this should go in the PXELINUX docs.  I don't think the
mapping hurts any already working configs, so it can be safely
added.

Since this is an onboard controller, meaning it's actually motherboard 
BIOS bug, can you give me details about your motherboard and BIOS?

It sounds like a useful thing to put on the "hardware compatibility" 
webpage.

I need to figure out some way to make the web pages and the 
documentation from common source, they keep getting out of sync...

Note to self: double check fixes...

Of coarse this should read:

r ^([[:graph:]]*)(.*)$ \1
