LILO may be used to boot a system yep. and even that may go wrong. > Hmm, I'm not sure how to convince you :-) try running lilo with -v -v -v Then you might see the BIOS drive number, geometry it assumes etc. You will probably see only _one_ disk and in that case your system boots by sheer luck. With -v -v -v I discovered why my system refused to boot from raid 1. It appears to actually boot from the first disk in the raid set, e.g: md1 : active raid1 hdg1[1] hda1[0] ^^^^^^^ This is mounted on /boot and lilo will boot from hda1 (bios disk 0x80). I had to reassemble the raid set in opposite order to get this because hdg is unbootable (lilo assumed bios drive 0x81). But maybe my lilo is old (21.4-4). --=20 =46rank - To unsubscribe from this list: send the line "unsubscribe linux-raid" i= n the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
