Cannot open root device "hda1" or unknown-block(0,0)

Hi!

Trying to upgrade to kernel 2.6 (actually, 2.6.18) from 2.4.27, when I
boot my system with 2.6, I get the following error:

VFS: Cannot open root device "hda1" or unknown-block(0,0)
Please append a correct "root=" boot option
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)

and then it's stalled, of course. I have no such error with 2.4.27.

I posted the content of my /boot/grub/menu.lst file here:

Everything seems ok to me.

Anybody has any hints?
