Intel SE7501WV2 User Manual

 

The SE7501WV2 server board is capable of wake up from several sources under a non-ACPI 
configuration, e.g., when the operating system does not support ACPI. The wake up sources 
are defined in the following table. Under ACPI, the operating system programs the ICH3-S and 
SIO to wake up on the desired event, but in legacy mode, the BIOS enables/disables wake up 
sources based on an option in BIOS Setup. It is required that the operating system or a driver 
will clear any pending wake up status bits in the associated hardware (such as the Wake on 
LAN status bit in the LAN application specific integrated circuit (ASIC), or PCI power 
management event (PME) status bit in a PCI device). The legacy wake up feature is disabled by 
default.
