There might be a hard BIOS limitation on the RAM to 256/slot and/ or a high density RAM limitation. You will have to research that as it might be able to handle 512 meg, spread across two slots.
"Supposed NIC drivers" scares me. If you are getting a code 10, it is obviously detected. Reverify the actual ID of the NIC and the proper drivers. Might try safe mode, then uninstall/reinstall if you are sure drivers are correct, verify all of the networking components are installed as well. Sometimes device IDs can be dependant on the serial number/production date as manufacturers can change hardware on a whim.
Wish you luck
