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
previously.

Snip from a post I just found on google:

---Snip---
"cd booting is one of the necessary features for FILO, especially
parsing
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
list.

Ug! ;-)  No wonder people are just statically defining or typing in
"hdc:/isolinux/vmlinuz"!
