hi

trying this:

--
boot=/dev/md0
map=/boot/map
install=/boot/boot.b.hda
backup=/boot/boot.b.rs.hda
prompt
timeout=50
lba32
raid-extra-boot=/dev/hda,/dev/hdb
...

with lilo-21.4-4 (standard with rh73) it won't accept the raid-extra-boot option

and

with lilo-22.3.1, it won't accept (i beleive boot=/dev/md0)

[root@jumbo lilo-22.3.1]# lilo Warning: using BIOS device code 0x80 for RAID boot blocks Fatal: Filesystem would be destroyed by LILO boot sector: /dev/md0

thanks

roy
