I use the integrated on the MB.

I wrote a letter to gigabyte tech support but until I get the response I would be interested in your opinion about my issue.

I was making a BIOS upgrade (which I know is not recommended) with @BIOS because I couldn't access the BIOS (delete) all I got was a black screen and then the system stopped loading.
After I finished the BIOS upgrade nothing has happened still couldn't get in the BIOS. Then I decided clr cmos to get back factory defaults. So I removed the battery for 5 minutes with computer unplugged and power button pressed for removing residual energy in the circuits. And since then when I turn on the computer I get one short beep and black screen. (power led on, hdd led not flashing).
I would welcome any suggestions regarding this issue. I know that this MB has backup bios. I assume the main bios is gone so I would appreciate any methods how to force the backup bios to kick in.
