*The Super I/O detects a power button event using the 'PSIN' pin. When a power button event occurs, the power-

up logic of the Super I/O sets 'PSOUT#' low and asserts 'PWRBTN#' of the module's chipset. The Super I/O also

sets the 'PWRCTL#' pin to low, which asserts the 'PS_ON#' signal and switches on the ATX power supply.

1-2 SUS_S3# <<<<

2-3 SUS_S5#

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.

JPZ3: AT Power 5V Setting

With an AT power supply is connected to

the Express-BASE, JPZ3 can be used to

provide 5VSB to the COM module from

the carrier board.
