Boot sector > 1024 cylinders

Hello all,
I cud install linux (red hat 7.1) on fat 32. but the performance is very poor. So i created partition, 1 for linux native (2GB) & 1 for swap (150MB). But while installation, the swap drive can be created, but while creating native, I get error that boot sector > 1024 cylinders.
Pl. help.
I have 40 Gb hdd. From win98se i can see
C: 10 gb
D: 15 GB
E: 10GB
F: 2GB
G: 150MB
I want to use F: & G: for linux.

Hi There!

The error means the following:

As BIOS can only access the first 1024 Cylinders of any Harddrive, the boot partition(s) need to be within the first 1024 cylinders of the harddrive.
I've heard that later versions of Lilo don't have this problem, but it seems that this doesn't apply to you.

You will have to create a /boot partition (~12MB) at the beginning of the HD. Try getting a Partitioning tool like Partition Magic to do so.

That will fix the problem.

Have fun, Steave.

The problem could be that:

(a) lilo can't access past 1024


(b) the BIOS can't access past 1024

If the latter then you don't really have much choice except replacing the MOBO (or putting the /boot partition at the front of the hard drive.

The former is MUCH more likely...

Just boot from a Linux boot floppy, log in as root, edit the file /etc/lilo.conf, in the top section (before the first section starting image=) add a line:

Then run /sbin/lilo
