I'm new to this forum and I wanna start of by saying hello to everyone. I hope this isn't the wrong forum for this kind of post. Sorry in advance if it is. My problem today is flashing my BIOS. There is some trickery going on and I want to run this by Tom's first for any help. Motherboard: ASUS P5GC-MX/Medion/SI Current BIOS: American Megatrends Inc. 0106, 7/19/2007 I bought this motherboard from Geeks.com and they advertised it as P5GC-MX/S. The one listed on the ASUS website is listed as P5GC-MX. I wondered what the /S meant before I purchased it from Geeks and I did no research to what it was about. It wasn't until I received the motherboard and got everything up and running to discover its some custom motherboard for the PC vendor Medion and that explains the /Medion/SI. I have been pondering using the BIOS file from the ASUS website but I am scared to flash it with BIOS version: 0518 since the BIOS that reads on mine is 0106 which isn't even listed under the downloads on the ASUS website. I can access the EZ Flash feature on the motherboard via Alt + F2. I'm afraid I'll end up with a dead board if I do try to flash it. I did download the ASUS Update program on their website and it allowed me to save the current BIOS to a file. Still weary to try anything though. *EDIT* I have a buddy sending me a Core 2 Duo E4600 and I would like to see if I can update my BIOS to fully support this CPU and able to have overclocking abilities, etc. I don't want a limited Medion BIOS if thats possible. If I do flash to 0518 and it does not work will I still be able to access EZ Flash and revert it back to the original I saved through ASUS Update utility? So I am in a pickle here. Any and all help would be greatly appreciative. If there is any other information that I should submit to help further just let me know and I will post back ASAP. Thanks!
