Configured the BIOS settings yet? Make sure your set the RAM to run as Supports DDR400/333/266 non-ECC, un-buffered memory Max. capacity of system memory: 2GB
the RAM you installed and to match the CPU bus. And there's probably several other settings that need to be tweaked as well. For example, if you're not running RAID, disable it.
If the problems continue, you may wanna try updating the BIOS. Actually, I just had a look at the ASRock site & here's what the latest BIOS fixes: "Modify MAC address function algorithm"

My asrock p4vm890 is has invalid mac address for both cmos and bios


The MAC is the unique identifier for the onboard LAN chip - if it's invalid then the chip has been fried - disable it from the BIOS and install a new PCI LAN card.

Mac address is invalid in both cmos and flash


The MAC address is burned in the Ethernet card chip, you won't see it in the Bios or if you do you can't change it. MAC address changer are tweaks to not being tracked.

The solution to know if the card is blown is to do a complete reinstall of your operating system and if then you can't connect whit it, it is indeed dead. Then Disable it in the Bios and had a PCI one to replace it.

Those kind of problem whit network cards happens a lot when you get a power outage, if you had one in the last couple of days your problem is most likely it.
