Cannot get ACPI S3 to work on Intel D845EBG2 board

Hello!

I am trying to get ACPI S3 Suspend to Ram to work with Wake on LAN on a
2.0GHz P4 and D845EBG2 motherboard. I have another machine on which it works
perfectly: an AMD Athlon 2200+ on a SOYO KT400 DragonLite board. All
computers are hooked to a Netgear FVS318 firewall/router with a built-in
8-port 10/100 switch.

The Intel D845EBG2 board will not stay in standby if Wake on Lan is used. It
will go into standby, but comes out immediately if Wake on LAN is used on
the Intel Pro/100 VE NIC. If I disconnect the network cable, turn off the
router, or disable the Local Area Connection in the OS, it will go into
standby and stay there until I hit a key or move the mouse. If the NIC is
not set to wake the system, S3 works perfectly. Sometimes after rebooting,
it will go into Standby and it will stay there (one time only) until a LAN
event wakes it (ping or pcAnywhere). After the first time it works
correctly, it fails on every subsequent attempt to enter Standby until I
reboot again...the monitor goes off for a second, then comes back on. Again,
disabling the NIC, disconnecting it, turning off the router, etc, all let it
go into Standby and stay there.

The Intel board has its NIC set to wake the system from standby (an Intel
Pro/100 VE Network Connection NIC). The Soyo board has an onboard Realtek
8139 NIC. I tried a D-Link DFE530TX+ NIC, which is recognized by XP as a
Realtek 8139, but that also pops right back from Standby, even if I load the
D-Link XP driver.

If I use Intel ProSet to change some parameters, the system will only go
into Standby and stay there if I disable the "Wake on directed packet"
setting. This is good in that it at least goes into and stays in Standby,
but useless for me, since I want pcAnywhere (or a ping from the router
itself) to wake it up.

I have changed ports on the router, made sure nothing is forwarded from the
router to this machine's IP address, changed the IP address, and probably a
few other things I cannot even remember. I need to have this thing in
standby and wake up from the NIC when I access it remotely.

The BIOS is set for S3 and a fresh install after setting S3 in the BIOS
makes no difference.

Any ideas?

OS is XP Professional
512MB DDR RAM
Pentium 4 2.0GHz
Intel onboard Pro/100 VE NIC
ATI Rage 128 AGP 4x video
WD 40GB hard drive
52X CDROM
3.5" Floppy

Thank you for helping!
