ECS P6BAT-B Ver 1.2a 08/03/1999 and FSB 133MHz

Hello!

I have ECS P6BAT-B ver 1.2a. BIOS is
08/03/1999-693-596-ITE86-P6BAT-00

I can't remove heatsink from chipset (glued) so I can't check which version of 693 chipset I really have(with A or without).
Is it possiible to setup 693 (without A) to support Coppermines with FSB 133MHZ or it is possible only for 693A???. Is it possible to tweak it for PIII 1GHz (7.5x133MHz) Coppermne with MS6309 FCPGA 2.0 Socket?

Please HELP anyone with experience with 82C693 chipsets family!

I have PCB which is the same like
PCCHIPS M765VMRT ver 1.3
but I don't know with which 693 version of chipset.
