The COMBOOT will answer my problem. But my problem aside, is it possible
to do something like

If multi(0)disk(0)rdisk(0)partition(1) has type c (label 2
kernel memdisk
initrd=winstall.img)

If multi(0)disk(0)rdisk(0)partition(1) has type 82 (label 2
kernel memdisk
initrd=linstall.img)

Ofcourse "c" is the type of Win95 FAT32 partition and "82" Linux Native,
and multi(0)disk(0)rdisk(0)partition(1) is /dev/hda1 is linux terminology.

I am trying wrap my head around the expressive power of isolinux.cfg.
Basically, can we take some run time decisions, just by structuring
isolinux.cfg correctly?

The only runtime decision it can take, AFAIK is "if no key pressed within
X seconds, then run this image else run image specified at prompt".
