LILO and large HD (IBM 755c)

I recently purchased a "large" 1.08 gig HD and have installed Linux
on in a small "boot/rescue" partition (/dev/hda2) which lies "below 500",
but I have been unable to get LILO to work. I can of course boot
from floppy.
It is the case that /sbin/lilo installs lilo, but when I try
to boot with LILO, I get
LI
and then the system hangs.
According to fdisk, the HD geometry is 2362,15,60
I'm running a 755C with a 1.2 Gb disk right now. LILO works fine.
The kernel reports my disk geometry as "2358/16/63" in
"/var/log/messages"; fdisk sees it as "589,64,63".
Here are some relevant questions:
* How does DOS see your geometry?
* What version of the BIOS are you running? (I believe you need 1.15
or later to use large disks.)
* What version of the Linux kernel are you using (I'm running 2.0)?
I will guess that DOS sees your geometry as "590,60,60". If so, you
can fix this by adding an appropriate "hda=..." to your LILO "append"
string (or "hd=..." if you are using Linux 1.2). That will force
fdisk to recognize your geometry in an appropriate way.
I used to force the geometry of my disk when I was using Linux 1.2,
but since I upgraded to 2.0 I haven't needed to do this.
