I found it stefan. I'm not not well knowledgeable with Isolinux, but
didn't want to just assume syslinux.cfg was the culprit like you said
Snip from a post I just found on google:
"cd booting is one of the necessary features for FILO, especially
isolinux.cfg files but it needs a little bit restructuring and I never
got around to do it yet. If someone wants to have a look, please do!
Maybe parsing CMOS variables would go well with that."
I believe this was posted by Richard Smith around July 2006 on Linuxbios
Ug! ;-) No wonder people are just statically defining or typing in
