PCI IRQ Settings (G7 servers) These options configure the legacy IRQ for embedded and slot-based PCI/PCIe devices. Multiple devices can share an IRQ. The PCI Devices menu displays the configuration settings of the PCI devices installed in the server and allows you to modify the IRQ. Multiple PCI devices can share an interrupt. To disable a device, select the device and press the Enter key. A menu is displayed with options to change the IRQ, as well as to disable the device. PCI Device Enable/Disable (G7 servers) These options enable and disable the embedded and add-in devices. Disabling devices reallocates the resources (memory, I/O, and, in some cases, option ROM space) that would normally be allocated to the device, and in some cases, saves the power that would be allocated to the device. NOTE: Only IRQs that are modified in RBSU retain the change during the next reboot. IRQs on PCI devices that have not been modified are subject to change during reboot. IMPORTANT: When the PCI Hot Plug driver is installed on servers with Microsoft® Windows® 2000 or Windows Server® 2003, disabling a single PCI controller also disables all controllers on the same PCI bus. To avoid disabling other controllers on the bus, remove the single PCI controller. RBSU menu (HP ProLiant G7 servers or server blades) 45

PCI IRQ Settings (G7 servers)
These options configure the legacy IRQ for embedded and slot-based PCI/PCIe devices. Multiple devices
can share an IRQ.
The PCI Devices menu displays the configuration settings of the PCI devices installed in the server and
allows you to modify the IRQ. Multiple PCI devices can share an interrupt.
To disable a device, select the device and press the
Enter
key. A menu is displayed with options to
change the IRQ, as well as to disable the device.
PCI Device Enable/Disable (G7 servers)
These options enable and disable the embedded and add-in devices. Disabling devices reallocates the
resources (memory, I/O, and, in some cases, option ROM space) that would normally be allocated to the
device, and in some cases, saves the power that would be allocated to the device.
NOTE:
Only IRQs that are modified in RBSU retain the change during the next reboot. IRQs
on PCI devices that have not been modified are subject to change during reboot.
IMPORTANT:
When the PCI Hot Plug driver is installed on servers with Microsoft®
Windows® 2000 or Windows Server® 2003, disabling a single PCI controller also disables
all controllers on the same PCI bus. To avoid disabling other controllers on the bus, remove
the single PCI controller.
