Hello,
i have some questions about "optimal BIOS" settings suggestions. Are there currently some generel bios settings
that should be disabled or enabled for proxmox to work stable/properly? I know for e.g. that other
virtualisation software recommends to disable PCI PERR/SERR Support.
So should be the following or other settings be enabled or disabled?:
PCIe/PCI/PnP Configuration
(1) PCI PERR/SERR Support
(2) Above 4G Decoding (Available if the system supports 64-bit PCI decoding)
(3) ASPM Support
Use this item to set the Active State Power Management (ASPM) level for a PCI-E device. Select Auto for the system BIOS to automatically set the ASPM level based on the system configuration. Select Disabled to disable ASPM support. The options are Disabled and Auto
CPU Configuration
(1) X2APIC (Extended Advanced Programmable Interrupt Controller)
Based on the Intel Hyper-Threading technology, each logical processor (thread) is assigned 256 APIC IDs (APIDs) in 8-bit bandwidth. When this item is set to En- able, the APIC ID will be expanded from 8 bits to 16 bits to provide 512 APIDs to each thread to enhance CPU performance. The options are Disable and Enable.
(2) Coherency Support (Non-Isoch)
Select Enable for the Non-Iscoh VT-d engine to pass through DMA (Direct Memory Access) to enhance system performance. The options are Enable and Disable.
(3) Coherency Support (Isoch)
Select Enable for the Iscoh VT-d engine to pass through ATS to enhance system performance. The options are Enable and Disable.
SATA
(1) Support Aggressive Link Power Management
When this item is set to Enabled, the SATA AHCI controller manages the power usage of the SATA link. The controller will put the link in a low power mode during extended periods of I/O inactivity, and will return the link to an active state when I/O activity resumes. The options are Enabled and Disabled.
Power Configuration
(1) Watch Dog Function
Select Enabled to allow the Watch Dog timer to reboot the system when it is inac- tive for more than 5
minutes. The options are Enabled and Disabled.
Thanks
