Hi guys,

I have (among others) a 440BX socket 370 motherboard: Chaintech 6BJM0-D100A
Until today, I was running a Celeron 500 MHz on it, but since the motherboard seemed to officially support an FSB133 MHz overclock, I thought I'd give it a try and purchased a Pentium 3 1000 MHz FSB133 and also switched the RAM modules from the 4 x 64 MB SDRAM PC100 that I had, to some 256 / 512 PC133 modules that I had lying around (more on this later).
Well, the PC booted fine, I entered the BIOS, adjusted FSB/PCI frequency to 133/33 MHz (although the "auto" setting was probably doing that already) - not sure about the AGP frequency, though, I'm guessing it's 1/2 FSB but, it's not specifically mentioned anywhere. Still, the Voodoo 3 3000 AGP card doesn't seem to have a problem... yet.

So, the good news is that everything works fine, didn't notice any issue, ran multiple benchmarks and the system seems very stable after a few hours of playing with it.
However, the CPU is clearly not supported by my current BIOS version (apparently, the motherboard actually has the original BIOS, which was never updated):

Another strange behavior is with the new PC133 memory modules: it only sees half of the module's size.
So, if I add 256 MB, it will see 128, if I add a 512 module it will see 256... If I add both modules (256 + 512), yep, you guessed it: 384 MB total RAM. 😀 Also tried changing slots, same thing... Anyway, not a huge deal, 384 MB is A LOT for Windows 98 SE anyway, but I'm guessing that a BIOS update might help with this issue too.

Which brings me to.... yeah, a potential BIOS update. This motherboard seems to have been completely forgotten by the internet. There is virtually no information about it, no manual, no drivers (although, to be fair, drivers were easy to find from other manufacturers, since we're talking about a very common chipset). However, finding a BIOS update seems to be impossible. So, by any chance, does anybody own the same motherboard and maybe found a BIOS update long ago, when it was still available? 😀
Oh, and in case you are wondering why I need a BIOS update if everything seems to mostly work fine, it's my OCD, it won't let me sleep at night 😀)
