PCI bus control
Note
This page shows the interrupts and the correct
interrupt assigned to the devices.
Select PCI Bus Control to:
Ÿ
Change the master latency timer values for PCI bus 1
and PCI bus 2.
Ÿ
Specify the system board interrupt routing (IRQs) for
SCSI, Ethernet, video, and USB.
Ÿ
Specify the slot interrupt routing (IRQs) for PCI slots.
Ÿ
Enable and disable PCI device types (SCSI, video,
Ethernet) and slots. When a PCI adapter is defective,
you can use Alt+F1 at startup and then disable the
PCI adapter in order to enable the system to start up
successfully.
Note
Any changes you make to IRQs will not be reflected in
the PCI Interrupt Routing selection of this menu until
you restart the server.
Cache control:
Select this choice to define the
microprocessor cache state as enabled or disabled, and to
define the microprocessor cache type as Write-back or
Write-through.
Selecting write-back mode will provide the maximum
system performance.
Memory settings:
Select this choice to view the server
banks of memory and to enable or disable selected rows
of memory within those banks.
If a memory error is detected during POST or memory
configuration, the server can automatically disable the
failing row of memory and continue operating with reduced
memory capacity. If this occurs, you must manually
enable the row of memory after the problem is corrected.
Choose Memory Settings from the Advanced Setup
menu; then use the the Up Arrow (
↑
) or Down Arrow (
↓
)
key to highlight the row that you want to enable. Use the
Left Arrow (
←
) or Right Arrow (
→
) key to select Enable.
Advanced ISA settings:
Use this selection to set the
timer delay for ISA I/O recovery.
Service Processor IRQ settings:
Use this selection
to specify the IRQ the system-management processor is to
use and to synchronize the service processor clock to the
system clock.
