Syslinux - May 2009 - Embedding COM32 modules into pxelinux.0

Aside from it being part of the GSoC CLI rewrite project ("internal
module"), has anyone been playing with it?

I just hacked up my copy of pxelinux and it somewhat works:
hello.c32 and fancyhello.c32 work fine, meminfo.c32 "works", rosh.c32
doesn't.
It's likely i broke something somewhere while taking shortcuts thru
pxelinux. This might explain why more
complex modules fail. The basic idea seems to work tho.

Is there a size limit for pxelinux.0 (32kb, 64kb) ?

There is ... around 32K.  The build should fail if you run out of space.
