Hello,
It seems my mobo manufacturer is BCM from the Numbers site, but I am having troube finding the updated BIOS.
A detection program, Aida, reports Unknown for manufacturer but another program called Ctbios reports these specs:

Award ID-String: 10/09/1998-i440BX - W977TF - 2A69KB3FC-00
Board/BIOS Version: Micron Bios Version 2.2a
OEM: BCM
Chipset: i440BX-W977TF // Intel 440BX
Thanks.
