Wake on Lan - A7N266-VM

I am trying to get wake on lan working on my A7N266-VM motherboard. It has a
built in NVIDIA nForce MCP Networking Adapter and I am running Windows 2000
professional with all the latest updates etc. Bios version is rev 1004. I
considered updating the bios but none of the more recent versions seemed to
have any changes other than processor updates so I assumed it was not
necessary.
I have enabled on option in the bios called "Power Up On PCI Card". The
explanation in the bios says this will enable the PC to power up from
network or PCI modems. I have also enabled the option "Allow this device to
bring the computer out of standby." in the "Power Management" tab of the
Network Adapter Properties.
When I shut the box down the network card is no longer powered up, so I put
the PC into sleep mode and then send a "wake up" packet from my Linux box
using ether-wake. No joy.
I tried a PCI network card (SMC1211) but there is nowhere (that I could
find) on the motherboard to plug in the WOL cable and it did not work
either.
In addition, and I don't know if this is related to my problems or not, but
the "Allow this device to bring the computer out of standby." option in
Win2k gets lost every time I reboot the PC. This happened with both of the
network adaptors I tried.
Any ideas would be appreciated.
