Ok, are you saying that you managed to build miboot floppies using the old
woody miboot floppies, (i think woody came with do-it-yourself-miboot stuff,
not sure). This would then be a 2.6 kernel. Could you post me the config file
for this kernel ?

Could you also try the same kernel with the miboot from

Then do :

	gzip -9 vmlinux

	dd if=/dev/zero of=miboot_floppy bs=1024 count=1440
	hformat -l "miboot floppy" miboot_floppy

	echo device miboot_floppy > miboot.conf
	echo kernel vmlinux.gz root=0200 load_ramdisk=1 prompt_ramdisk=1 devfs=mount debconf/priority=medium >> miboot.conf
	miboot -c miboot.conf

If this works, it would be nice to do the following :

  	objcopy -O aixcoff-rs6000 -R .stab -R .stabstr -R .comment -add-section=image=vmlinux.gz dummy.o vmlinux.gz

just after the gzip step, where dummy.o is taken out of
arch/ppc/boot/openfirmware, you need to do a make zImage to compile it.

mkvmlinuz -a used by d-i currently does this second step, which may be cause
fo this problem.
