see below for my original post

I've uploaded some files to http://karlsbakk.net/bugs/ that may help to
explain the problem. Still - I can't boot from nothing but floppy.

thanks

uhm,
some versions of lilo used to write to the mbr when told boot=/dev/md?
others to the first sector of the container partition.

you better put a standard mbr on the disk and mark as active the partitions
that are part of md0

hi ya

how was the floppy made ??
	- does it have a initrd file ??
	- initrd is notlisted in your lilo.conf.hda
	- is the kernel on the bootable floppy the same as that
	referenced in lilo.conf ?

i'd take out all those explicit defines and see if it helps

simplified(?) lilo.conf
	boot=/dev/md0
		- not sure about boot= for /dev/hda vs /dev/md0
	map=/boot/map
	install=/boot/boot.b
	prompt
	timeout=50
	lbad32

	image=/boot/vmlinuz	   
	   root=/dev/md0
	   label=raid
	   read-only

-- you'd also want to use /dev/hda  and /dev/hdc ...

c ya
