Boot Priority
The HP Server's boot order should be considered when selecting a PCI slot on the
system board. This is especially important if you are installing a board that
requires an early number in the boot order. The board's boot priority is set by its
slot location in the boot order.
By default the HP Server searches for boot devices in this order:
1. SCSI
2. PM
3. SM
4. PS
5. Other Boot Devices
IDE DVD drive
Flexible disk drive
6. PCI slot 1
7. PCI slot 2
8. PCI slot 3
9. PCI slot 4
10. PCI slot 5
11. PCI slot 6
12. PCI slot 7
13. PCI slot 8
14. PCI slot 9
15. PCI slot 10
The SCSI controller chip interfaces the PCI bus to two Ultra3 SCSI buses and
contains an onboard RISC processor. The RISC processor is a fully autonomous
device, capable of managing multiple I/O operations and associated data transfers
from start to finish without host intervention. It provides power management
feature support in accordance with the PCI Bus Power Management Interface
Specification.
