How do I add a SATA drive to a system that already has an IDE drive?

[Derek Tattersall <tatters@xxxxxxxxxxx>]

I have a system that has a motherboard with both SATA and IDE on it. I
have an IDE drive as /dev/hda, and a CDROM drive as /dev/hdb with FC4 on
the IDE drive. I have acquired a SATA drive and would like to add it to
my system. If I just plug it in, the computer hangs at with a message
like GRUB: Loading stage 2. 

I set up the system bios to boot off of hdd0, and it seems to do that -
at least it starts booting the grub bootloader, it just doesn't get very
far.

Can anyone tell me how to set up grub so I can still boot the computer
off of the IDE drive and then use the SATA drive for extra storage? I
don't want to re-install the operating system or move it to the other
drive if I can help it. 

The motherboard is an ASUS K8V Deluxe with a Via chipset.

Thanks.
