Unable to boot kernel


I compiled my own kernel following these instructions: http://www.debian.org/doc/FAQ/ch-kernel.en.html When I try to reboot in my new kernel I get this error message:

"Cannot open root device"

I checked my menu.lst everything appears to be fine:

Code:
title		Debian GNU/Linux, kernel 2.6.15-1-486
root		(hd0,1)
kernel		/boot/vmlinuz-2.6.15-1-486 root=/dev/hda2 ro 
initrd		/boot/initrd.img-2.6.15-1-486
savedefault
boot

title		Debian GNU/Linux, kernel 2.6.15-1-486 (single-user mode)
root		(hd0,1)
kernel		/boot/vmlinuz-2.6.15-1-486 root=/dev/hda2 ro single
initrd		/boot/initrd.img-2.6.15-1-486
savedefault
boot

title		Debian GNU/Linux, kernel 2.6.15
root		(hd0,1)
kernel		/boot/vmlinuz-2.6.15 root=/dev/hda2 ro 
savedefault
boot

title		Debian GNU/Linux, kernel 2.6.15 (single-user mode)
root		(hd0,1)
kernel		/boot/vmlinuz-2.6.15 root=/dev/hda2 ro single
savedefault
boot
The 486 kernel boots fine, my own kernel doesn't. The only difference is the inird file which isn't mentioned in de Debian manual What can i do?

Did you remember to compile in your chipset and root filesystem type (for example mine is piix and ext3)? If you don't use initrd, they have to be compiled in as "Y" instead of as "M".

I think the chipset is the problem! Where can I set this?

When you do make gconfig (or xconfig) to configure your kernel, it is buried under "Device Drivers". If you have ATA (i.e. IDE disks, not SATA or SCSI) you'll want to go under the ATA/ATAPI/IDE section and then into "PCI IDE Chipset Support" and then to "Generic PCI bus-master DMA support."

At leat that's how it is on the 2.6.16.19 kernel that I compiled last month.

You'll just have to poke around a bit under device drivers. Make sure you know what your chipset is.
