Default How do I change the HD mode in the BIOS in presario 4840?

I just recently aquired one of these older things and I am trying to
install Linux on it. I managed to install it once. Then just after
adding a graphics card all hell brakes loose on this thing.

I believe I have found a solution, and it requires for me to change the
Harddrive mode (LBA thing). How do I change it!?

There is no upgrade for the bios. I looked it up at HP for firmware.

Any help be most helpful

By the way to get linux SuSe 10.0 to work on a Compaq Presario 4840 with
the the standard onboard graphics ATI Rage 4mb , use LiLo

AHA!!! Figured it out.

Make a boot Partition at the beginning of the drive. Basic size is 10mb
but 15mb if you want to test with the kernel. The kernel and linux is
designed to support LBA. Just if old motherboards aint, you just ignore
it, if you can.

First I doubt seriously a 160 GB drive will work. The 4800s do not support
48-bit LBA which is required for drives larger than 127GB. Secondly, the
BIOS in that series is very basic with no HD parameter settings. In fact,
there is an 8 GB HD size limit on the 4824 and below. You might try
installing a PCI IDE controller with its own onboard BIOS.

I have a fully working version Linux on the Compaq 4840, The LBA issue
is BYPASSED by making sure the boot/ partition is at the beginning of
the partition list, after making the swap/ and the /(root). Linux
fully supports large disks once it is booted!.

The boot partition has to below the first 1024 cylinders of the harddisc.

Please don't damage the list again.

Current partition setup of my SuSe Linux 10.0 is as if you wanted to
know. The boot has to be at the TOP! (the first)

CYLNDER SIZE
Mount Start End Partition Type
----------------------------------------
/dev/hda 745GB Samsung 0 9732
/dev/hda1 15.6MB /boot 0 1 Linux Native (ext3)
/dev/hda2 823.6MB /sawp 2 106 Linux Swap
/dev/hda3 73.7GB / 107 9732 Reiser

Works a treat

As the OP states, Linux is a different beast. I ignores the BIOS and goes
direct to the iron with register-level commands to figure out the hard drive
geometry, then use it. Would that billg and his minions were so clever!
