I used to have a 6VBA 133 MB that I disabled trying to flush the BIOS. I am sure some of you have exprienced the same pain. I have an intel 733MHz slot1 processor and a replacement MB was impossible to find for it now. So I got a used SY-6BA+ 100 instead. My problem now is it is not reporting the correct size of SDRAM PC 133 Module, (for example instead of 394 from a 256 and a 128, it counts only 260. I read on the manual at SOYO and it says it deos support 133. Is there any jumper or setup I have to do? Deos it really support the PC133 module at all? thank you. abebe alimuz
