It's been 3 weeks since the modified BIOS was flashed. The board works great! Activation is stable))! During this time, I made an ISO image with the "ASUS Win 7 OEM:SLP" distribution from a Asus K50in Recovery DVD. I replaced the drivers for the B85M-G board in the distribution, and now I can restore the PC to a working state in 20 minutes))!
