Hoping someone can suggest something here for me. I was running bios 402 and decided to upgrade my RAM and Harddrive and switch to windows x64. So not wanting to have to go through the process of registering again I used the ssv3 and andys tool to give me a 702 version of bios. I loaded the original 702 and then then modified one. Everything works fine except there is no long a nic!! In windows it says it can not start the adapter with error code 10. In windows the lights on the nic turn off just after the windows logo. If I load ubuntu and try and manually start the NIC I get "RTNETLINK answers: Cannot assign requested address" however the NIC lights are on and flashing. However, while the lights are flashing it also says that there is no cable plugged into the ethernet port. However there is. I've seen messages else where that the realtek drivers can manage to dissociate the PHY layer so I trie unplugging the machine and taking the CMOS battery out left it for an hour and rebooted....but got the same thing. I've tried reverting to 0402 firmware but it has the same issues. I'm gathering that this is something to do with Realtek but simply can't get it to the start where it wishes to reattache the PHY layer again. Anyone else come across this?
