2 System Information
Boot Drive Priority
The on-board SCSI controller has two channels, A and B. Channel A is typically used to control the Hot
Swap SCSI drives. Channel B is typically used to control the internal non-hot swap SCSI drives. On each
SCSI channel, the NetServer scans for a boot device starting at device ID 0 and proceeds up from there. The
HP NetServer's boot order (BIOS search order for a boot device) should be considered, when connecting
cables from the on board SCSI channels. A SCSI drive’s boot priority is set by the drive’s location in the boot
order.
You can change this boot order using the Setup Utility (BIOS) and the SCSI Configuration Utility during the
boot process. By default the NetServer searches for boot devices in this order:
1. IDE CD-ROM drive
2. Flexible disk drive
3. SCSI A bus (typically Hot Swap Mass Storage Cage)
4. SCSI B bus (typically non-Hot Swap internal SCSI devices)
5. PCI Slot P1
6. PCI Slot P2
7. PCI slot P3
8. PCI slot P4
9. PCI slot P5
10. PCI slot P6
11. PCI slot P7
12. PCI slot P8
IRQ Settings
The BIOS automatically assigns the IRQs (hardware interrupts) for each PCI slot and embedded device in
the HP NetServer during boot. These assignments trigger the NOS to enable the APIC (Advanced
Programmable Interrupt Controller). APIC takes advantage of the expanded set of non-conflicting IRQs for
those accessory boards requiring more than one IRQ per slot. APIC provides up to four dedicated interrupts
for each PCI slot.
These automatic IRQ assignments can be changed in the setup screen (F2).
Connector Pinouts
Video Connector Pinouts
The built-in video uses the standard 15-pin analog display pinout configuration. The pinouts for your monitor
may vary. For the pinouts for your monitor, refer to the manual that came with your monitor.
