(PCI/PCI-E Parity Error) event occurs on a PCI/PCI-E slot for PERR reporting. The
options are Enabled and Disabled.
PCI SERR# Support
Select Enabled for the BIOS to generate a SERR number when a runtime SERR
(System Error) event occurs on a PCI/PCI-E slot for SERR reporting. The options
are Enabled and Disabled.
PCI PERR/SERR Support
Select Enabled to support PERR (PCI/PCI-E Parity Error)/SERR (System Error)
runtime error reporting for a PCI/PCI-E slot. The options are Enabled and Disabled.
