Hi all, I have in my possession a vintage Sony VAIO PCV-RX750 with ASUS motherboard model P4S266VX (OEM for Sony VAIO) . Is it possible to unlock any hidden menus and/or update OROMS in this BIOS (VAD1003)? This is a rather ancient Award BIOS. Motherboard BIOS String: 05/21/2002-SiS650-P4S266VX BIOS Revision 1003 See BIOS file VAD1003.BIN attached. I extracted it from the Sony BIOS Update Flasher (SOA003XDFL.EXE). Thanks!
