Hi all,

I am currently working on a Red Hat 7.1 system, running on a Fujitsu
Primergy - with built-in SCSI.

I've had to move the tape drive from /dev/hdb to /dev/hdd - it's an IDE
drive - so I updated /etc/lilo.conf to recognise this (I have SCSI emulation
for this tape drive), and ran...

lilo -v

to rewrite the boot sector.

Rebooted, and.... nothing!!

apart from...

LI

This generally means a geometry mismatch. This often occurs when lilo and the bios disagree about the ordering the drives. Look in /usr/share/doc/lilo-*/README for detail on what each letter means.


on the screen, where my system should be booting!

If we didn't have a rescue disk, we'd be screwed !! Fortunately we did have,
now we have two!! just to make sure! :)

BUT - what has gone wrong? What does this LI mean?

Here's what I did and what happened....

[root@server /]# lilo -v
LILO version 21.4-4, Copyright (C) 1992-1998 Werner Almesberger
'lba32' extensions Copyright (C) 1999,2000 John Coffman

Reading boot sector from /dev/sda
Warning: /dev/sda is not on the first disk

This means lilo thinks that sda is not the 1st disk in the bios boot order. Do you have any ide hardrives? If you are sure that sda is the 1st drive as the bios sees things. (You should check the harddrive order in the boot tab of the bios.) Add this to the 1st section of lilo.conf:

disk = /dev/sda
bios = 0x80

Merging with /boot/boot.b
Mapping message file /boot/message
Boot image: /boot/vmlinuz-2.4.2-2
Mapping RAM disk /boot/initrd-2.4.2-2.img
Added linux *
/boot/boot.0800 exists - no backup copy made.
Writing boot sector.
[root@server /]# reboot

If anybody could explain what has happened here, I'd be eternally
grateful....

If anybody can tell me how to put the system back to booting from the hard
disk, I'd be even happier!!

thanks for any help,

Regards,

a "worried" Greg Conway!
