thank you ! your bios file is really helpful for me . my desktop lenovo m4600t board model IS7XM REV1.0 getting malfunction after I plugged out and in the HDD power and data cable.when i press power button, no signal on my monitor,but sometimes could show lenovo logo and go off. so i think this issue maybe caused by bios file. after rewrite bios file, my desktop could boot normally...
