Configuring Specific Pcie Devices - HP ProLiant Gen10 User Manual

Configuring specific PCIe devices

Configuring specific PCIe devices
Use the PCIe Device Configuration options to enable or disable, and select configuration settings for embedded and added-in PCI
devices. Disabling devices reallocates the resources (memory, I/O, and ROM space and power) that are normally allocated to the device.
By default, all devices are enabled.
Procedure Procedure
1. From the System Utilities screen, select System Configuration > BIOS/Platform Configuration (RBSU) > PCIe Device Configuration .
2. Select a device from the list.
3. Select settings. Depending on the device, options include:
Device Disable
Auto—The device is automatically enabled at server boot.
Disabled—The device is not automatically enabled.
PCIe Link Speed
Auto—Sets the link speed to the maximum supported speed of the PCIe link.
PCIe Generation 1.0—Sets the link speed to a maximum speed of PCIe Generation 1.0.
PCIe Generation 2.0—Sets the link speed to a maximum speed of PCIe Generation 2.0.
NOTE: NOTE:
If this feature is not supported, the option is not available.
PCIe Power Management (ASPM)
Auto
Disabled
L1 Enabled—The device's link enters a lower power standby state at the expense of a longer exit latency.
PCIe Option ROM
Enabled—The platform optimally loads PCIe Option ROMs to save boot time.
Disabled—The platform disables all PCIe Option ROM optimizations, which might be required for older PCIe devices.
4. Save your settings.
