Does anyone have the offical Biostar MB-1333C/1340C motherboard manual they could share? I've tried for hours to get 256KB cache working on this board, but without success. I think the jumper settings found on the th99 site are incorrect for 256K. Jumpered in this manner doesn't even have voltage going to the cache. I tried to figure out more suitable jumper settings on my own, but have failed. I tried 32kx8 because that is what my other CHIPS-based motherboard uses for 256K, I also tried 64kx4, which is what the th99 sheet calls for. The board only seems to work with 64KB of cache. Has anyone had success in achieving 256KB cache on a CHIPS-based 386 motherboard?

I would like to avoid having to reverse engineer the cache implementation on this board. I'm sure the manual is out there somewhere.
