I have Redhat installed from CDROM onto a 1.1 gig quantum
which I installed as the primary of the second IDE port
od a P133. The first IDE port has 2 drives (DOS) the boot
drive being a 420 meg and the slave an 840 meg.

I can boot linux from the redhat boot disk I created
with the incantation linux ramdisk=0 root=/dev/hdc1
(hdc is partitioned into 4 partions including a swap)
hda and hdb are my dos drives of course.

Everything seems to function fine in both DOS and linux
but I want to install LILO

lilo complains about 0x82 bios drive may not be accessible
when I run it and a boot indicates the to common
LI
and hangs.

rebooting with the redhat bootdisk and the
linux boot incantation boots linux just fine.

What is wrong with this picture.
Am I not allowed to have linux on the master of a second
IDE port? What would the lilo.conf look like for this situation.

Any input would be appreciated.

Someone no doubt will correct me, but I believe lilo must find the
kernel image to boot on /dev/hda or /dev/hdb only. If you put Linux on
/dev/hdc, I think you are stuck with boot floppies or loadlin from DOS.

That's my experience as well.

i've made a small partition on /dev/hdb and installed /boot/* and a
kernel on it. Then I installed LILO in the partition boot record and
added i to OS/2 Bootmanager. Voila!

Your welcome to write for exact setup (I'm running OS/2 at the moment,
and can't access my linux partitions)

All my kernels live on hdc1 which is mounted as /. There appears to
be a problem with more than 2 EIDE drives. The LINUX IDE driver does
not seem to find the correct disk geometry for hdc and hdd. Also I
use the LINEAR option for LILO to get it to work. LILO also blabbers
some Warnings about maybe not being able to access a drive, but still
boots OK. I guess all these problems are the result of the old PC
BIOS and the generality that a piece of software like LIKO needs to
have, however it does work well.

That's what the redhat book says. But I've got slackware sitting on the
4th physical hard drive (7th partition, /dev/sdc). Can slackware do it
but redhat not?

Is your third drive an EIDE drive? If so you may have to add a couple more
lines to lilo.conf. I had the same problem trying to boot off of my 2.1GB
drive that was the master on a second controller. Just ignore the warning
message if your BIOS actually supports 2 IDE controllers.

The lines that I added were.
linear
disk = /dev/hdc
bios = 0x82
sectors = 63
heads = 16
cylinders = 4092

Change these lines to match your drive, but the 0x82 should be the same if
your trying to boot off of the third drive.

No, I can boot off my third drive with Lilo under Red Hat 4.0. It's only a
problem if your third and fourth drives are controlled by a controller
card and not the motherboard. I also had problems with Lilo.
