Hi guys, can anyone help me with this bios? It needs to be cleaned.

Motheboard: GDI5A LA-K033P REV 1.0 (A00)
Service TAG: BNV5GD3


I've attached the two BIOS (16MB and 8MB). The laptop turns on but only displays a backlight. I tried another BIOS and it works fine, but I can't exit manufacturing mode. Thanks to anyone who can help me....
