I have an ECS UM8810P-AIO rev 1.1 which I'm trying to use with an Am5x86-133. I have seen other people using this combo on the internet before but I'm not having any luck.
The board won't recognise the CPU. Comes up as '??? 100MHz'. It will boot with an ADZ stepping CPU but it seems quite unstable. It won't boot at all with a BDC stepping, yet its fine with a DX2/66. I've tried jumper settings for 486DX4 and Am486DXL but no luck.
Here's the jumper settings http://stason.org/TULARC/pc/motherboards/E/EL … M8810P-AIO.html
My board does have the voltage regulator and I've set it to 3.45V according to the silk-screened info on the board.
Should I be using a different CPU type?
I have managed to find a BIOS on the internet, version 32J dated december 1996 (my current version is dated november 1994). However the BIOS chip on my board is of type 27C010A-15 which I believe is NOT a flash EPROM. Interestingly, according to the above link there is a jumper setting for 5V/12V flash EPROM, and these jumpers are open on my board.
So I'm a bit confused. Is it possible to flash this BIOS, or will I need to get it UV erased and reprogrammed?
