I would like to know if external SRAM banks are on your motherboard and accepts it, if it is not installed, will it prevent my VGA from working?

Where can I purchase 256 or 512Kb SRAM?

I purchased a motherboard from the computer show, configured the jumpers, the onboard vga and sound and installed 2-32MB simm modules and all other required devices, but when i powered it up, it seem to be running post, but no picture.

The manual stated that the PAM-00631 Mainboard has a built-in cache controller, It requires external SRAM as Tag and data memory. I have never seen this before.

please help Rashidah@aol.com

As to the video, it is possible that the previous owner had disabled the on-board video. Try resetting the CMOS memory. You usually set a jumper and boot up the pc, then shut down, and set the jumper back to "normal".

I have seen similar problems when the memory was not "compatable" with the motherboard. Make sure that you have the correct type of SIMM for the motherboard, and that both SIMMs are the same.

It is also possible that the on-board video is bad.
See if you get any video with a PCI video card installed.

As to the Cache and such;
Are there any open small sockets on the motherboard?
There are several types of sockets used for external cache memory so you need to determine what type of cache the MB requires.

It also could be an explanation of the fact that the board has built-in external cache.
External cache is on the motherboard, internal cache is inside the CPU package.
