Hi and welcome to the forums.
What makes you think that? A BIOS does not just get "erased". Were you doing something (like trying to update the BIOS on the board and messed it up?) when this happened?
Hi, I was trying to replace the RTC battery on motherboard. Accidently power cut off from the CPU and never boots after that. All I see is AGP info, nothing else. Since CPU went off after I had removed RTC battery, I assume bios would have erased.
Please suggest if you have seen same symptom for some other reason. Thanks!
