PE840: wake on lan, wake on ring

The PE 840 uses an onboard Broadcom 5721J Controller. There is a
b57udiag utility that can be used from a DOS environment.

I believe the command to enabled WOL would be 

"b57udiag -w 1"

There may be a way to do it natively in Linux, but I am not familiar
with it. This is only at the NIC hardware level.

The network module you are loading would also have to support it.

Here is an article about it.

Thank you,

Can anyone confirm that PE840:
1) cannot do wake on lan
2) cannot do wake on ring

If wol is possible, since I see no evidence of it in the BIOS setup,
does it
mean you have to enable it via nic settings only (ie: ethtool) and no
option is available to enable/disable it?
