This probably means grub got installed to the MBR of a device that's not
the first one BIOS tries to boot, or you installed it onto a partition,
and XP goes is on the MBR.  Are you really sure BIOS knows that it's
supposed to boot the SATA drives first, _AND_ that the SATA controller
is set to boot its disks?

You're installing both of them on the SATA drives, and trying to put
grub on the MBR of the SATA drive?  What are the IDE drives for?

Let's get some data.  Run this as root:

modprobe edd
find /sys/firmware/edd/*/pci_dev/

What's it show?  Assuming there's an int13_dev80 and an int13_dev81 (and
any other directories you may see) in /sys/firmware/edd/, cat each
"host_bus" file, and be sure you show us which one's which, i.e.:

vroomfondel:/sys/firmware/edd/int13_dev80$ cat host_bus
PCI     00:1f.1  channel: 0

(I need to know how "int13_devXX" matches up to the contents).

then run "lspci", and paste the output here as well.

And then we'll at least know if the bios is completely useless, totally
full of misinformation, or (maybe) if there's an actual bug that we can
fix.
