Standard PCs boot via BIOS from one drive directly. RAID 5 doesn't reside on one disk. b-

Last I checked, GRUB did not have the RAID drivers to read RAID5 before the kernel was up. It can, however boot from RAID1.

Only if you get yourself a PCI card with a RAID BIOS on it and attach the disks to that.
The RAID BIOS hooks interrupt 13 and allows GRUB (or DOS or LILO for that matter) to see the RAID5 array instead of the individual disks.
Obviously any RAID card will do, it doesn't matter whether it has a CPU to do the RAID calculations or not (known as fake-RAID and ataraid if it doesn't).
