The floppy driver is ok under Windows in other PC. And format in FAT and FAT32 but nothing. This night I probe the 3.51 version and tell you my result. WHAT DISASTER. More that 10 motherboard flashed OK and brick the notebook more expensive. BAD LUCK. THANK FRIENDS.
Ahh forget my earlier quest for help with unlocked bios...i will get it somewhere else or mod my own!
