All ADLINK modules support S3 mode and
consecutive power down of ATX power supply.
For modules that connect the S3 signal, PS_ON#
should always be set to SUS_S3# as source (even when S3 mode is disabled in the BIOS). For
modules that do not bring out the S3 signal, PS_ON# should be set to SUS_S5# as source.
