Reasonable BIOSes simply get the geometry from track 0 and map sectors
accordingly. The first trick was determining the correct geometry.

I guess I could submit a patch ;-)

I didn't do any optimization. The kernel was compiled with "everything"
modules, and I included the complete modules subdirectory for that kernel
in a stock Debian root.bin. Still, there is some space available on the
current root.bin image file, and a bit of space still on the floppy image.

This means that there is lots of room for more inovative (and space
consumptive) installation techniques, at least for the CD installs.

The next problem I need to tackle is how to decide which modules to
install to complete the bootup. The kernel detects all the necessary
hardware during bootup, but I haven't found where it keeps that info yet.

If the scsi, or ethernet cards are pci, they are registered in /proc/pci,
and I have no problems parsing the scsi modules from that file. (BTW, the
graphics card is usually registered there as well which should be of help
to X installs)

This doesn't deal with the non-pci cards, or the proprietary cards.

I'd prefer not to ask any questions, not even "pick from the following
list". I'm searching for the "hands off" installation ;-)
