Ok, are you saying that you managed to build miboot floppies using the ol=
d
woody miboot floppies, (i think woody came with do-it-yourself-miboot stu=
ff,
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
http://people.debain.org/~luther/miboot

Then do :

 gzip -9 vmlinux

 dd if=3D/dev/zero of=3Dmiboot_floppy bs=3D1024 count=3D1440
 hformat -l "miboot floppy" miboot_floppy

 echo device miboot_floppy > miboot.conf
 echo kernel vmlinux.gz root=3D0200 load_ramdisk=3D1 prompt_ramdisk=3D1 d=
evfs=3Dmount debconf/priority=3Dmedium >> 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-sectio=
n=3Dimage=3Dvmlinux.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 ca=
use
fo this problem.

Friendly,
