Hello, I failed the bios update (from 1.70 to 1.90) and now it is corrupted. Tried with taking off the battery, switching jumpers and booting on usb stick. I thought the last chance before buying a new chip will be booting via dos with autoexec.bat to auto run with no need of keyboard input, but I do not know what commands should I put into that file.

1. Could someone help me with creating autoexec.bat?
2. As I understand I need to copy both - dos (.exe) and .rom files on usb stick?

My motherboard is Asrock 990FX Extreme3.
Thanks.
