My mobo is ASUS A8N SLI Deluxe and I want to try the mod bios for Vista OEM activation but I'm not sure which one is ok for my system. Can you tell me what's the difference between "ASUS A8N-SLI Deluxe (by Dajo, BIOS mod by replacing SRAT table, Success)" and "ASUS A8N-SLI Deluxe (Success)"? And Can I swicth back to the orginal BIOS from Asus? Thank you so much
