I'm assuming that you are trying to get Suspend to Disk (S2D) to
work. Are you getting a failure message when you attempt it?
There is some discussion on this issue in the archive (I asked
the question not too long ago).
If you are using LILO as your boot loader, and you installed LILO
into MBR, then that is your problem. As I learned recently, LILO
does not support the need to change the boot flags on the boot
partitions in MBR. Apparently, S2D will change the flags so that
the boot flag is set on the S2D partition so it will boot from
that device when you resume.
What I did to resolve this was reinstall LILO to my root
partition and then reboot to a WIN98SE diskette and run 'fdisk
/mbr' to install the Windows loader into MBR. This loader
supports the flag switching. I also changed the 'boot=' entry in
/etc/lilo.conf to be the root partition and reran lilo.
I hope this solves it...jc
