The label on the mother board is 6LTM M102 which is a Chaintech motherboard id for a Intel 440LX clone.
The problem is, when I break down the bios id the motherboard id is 6ESA M10X.
So which one do I use when I go looking for bios update?

The BIOS information is as follows:
BIOS Date: 11/03/97
BIOS Type: Award Modular BIOS V4.51PG
BIOS ID: 11/03/97-i440LX-W977-2A69JC39C-00
OEM Sign-On 11/03/1997
Chipset: Intel 440EX/LX rev 3
Superio: Winbond 977TF rev 0 found at port 3F0h
