Erik! First of all I donot have access to any DPM. But i can use high speed 8k x 8 or 32k x 8 SRAM and some logic with 4066 or 74LS244 or 74LS373 etc, to make it DPM.
The biggest problem is that i donot know any thing about PCI. I do not know its upper or lower speed limitation etc. Can you help me about understanding the PCI protocol. I know that ISA and EISA are just direct connections to System bus like address, data and control bus it also have, i think, DMA and interrupt controls. but i donot know how PCI Interface is composed.

Thanks!
