Anyone have any idea why I would get the following error on boot after configuring grub.conf?

VFS: Cannot open root device "sda3 or unknown-block(0,0)
Please append a correct "root=" option
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)

I have triple checked my grub.conf file and even compared it to another one on a working
machine and so far as I can tell it looks correct. According to what I could find in google,
this is a problem with not having SCSI support in the kernel, but the thing is that all the
drives are SATA. If anyone could lend me a hand I'd really appreciate it :)

You need scsi drivers in the kernel, in order to use sata discs :!:

With livecd, recompile your kernel. Then reboot :wink:

You will also need to know what type of SATA controller you have, so you can select the correct SCSI low level driver for it.

Thanks!, that was it :)
I added the SCSI disks and the generic SCSI support to the kernel.
The motherboard is an MSI K8N Neo3, which according to MSI has an NVIDIA
nForce4-4X Chipset which has two SATA controllers and two ata 133 controllers
so I added the low level driver for NVIDIA SATA and then recompiled.

This got me passed the VFS error however now it gets up to here
and then it just stops without an error:

ata1: SATA max UDMA/133 cmd 0x9F0 ctl 0xBF2 bmdma 0xF600 irq 11
ata1: SATA max UDMA/133 cmd 0x970 ctl 0xB72 bmdma 0xF608 irq 11
ata1: dev 0 ATA, max UDMA7, 3128108 sectors: lba48

Any ideas?
