Problem after install, while on first boot

[illuz1on]

Hey

I had a slackware 10 install going but it didnt work so well so I reinstalled over the old installation, formatting and etc..

I now tried booting after the new install and now it starts booting but halts with this error:

"Cannot open '803' " -- Think its trying to do root=803 or something
"Please append correct 'root =' option"

I boot cd again and then mount /dev/sda3/ in /inst and then looked at lilo.conf and it looks fine,

Says:
label = Linux
root = /dev/sda3
read-only

Anyone know what this could be from??

Thanks alot
