Red Hat Bugzilla – Bug 2609
new LILO confuses SystemSoft BIOS
Last modified: 2008-05-01 11:37:50 EDT
The version of LILO included with Red Hat 6.0 apparently
confuses the SystemSoft BIOS used on many low-cost AMD-based
laptop computers using the Intel TX Socket-7 chipset. It
apparently does not detect a valid boot signature on the
hard drive and refuses to load and run the boot sector.
Instead, the BIOS prompts for a floppy.
The computer boots up fine off of the boot floppy. Various
configurations of /etc/lilo.conf were tried:
a) Use "fdisk /mbr" from a Windows floppy, then set the
Linux partition as active. Use boot floppy into Linux, set
lilo.conf to write boot record to /dev/hda3 (the Linux root
partition). Run /sbin/lilo then reboot. Same result (BIOS
prompts for a floppy upon reboot).
b) Use boot floppy into Linux, set lilo.conf to write boot
record to /dev/hda. Same result (BIOS prompts for a floppy
Temporary work-around: boot off of the boot floppy,
downgrade to the Red Hat 5.2 version of LILO and run
/sbin/lilo . (With the same /etc/lilo.conf that did not work
with the Red Hat 6.0 version of LILO).
Note: This appears to be a BIOS-specific interaction. No
problems have yet been observed with LILO on desktop
machines using the AWARD or Phoenix BIOS.
We will need to obtain hardware that contains this brand of BIOS to
accurately troubleshoot the problem associated with LILO shipped with
6.0. This may take a while.
