How do I find out who made this MoBo?

How do I find out who made this MoBo?

I'm trying to upgrade this old PII 233 slot 1 box.

My idea is to put a Slocket in and a nice FCPGA chip but I'm thinking that might require an update to the BIOS and MoBo drivers and I can't work out what this board might be.

Known Info:
It's originally from Japan.
Spash screen says "Fujitsu"
Bios: Phoenix 4.0 Release 6.0 (4A4LL0X0-07A-0008-P04)

Numbers appearing on the MoBo:
E139761
Intel type AL440LX
CA21101-B861(C011)
IUAL 81025729 AA 681536-306 06F


Numbers appearing on the main chip:
259807AJE4
NSC96 A2
PC97307- IBU/VUL

Forget FC-PGA. It's an old LX chipset mobo. No Coppermine BIOS upgrade will be available and there are other issues with the voltage regulators.

Thanks, that'll save some time
