I bought a SIS 486G 3.3/5Vb Ver:I motherboard off of E-bay, complete with manual. This board is supposedly New Old Stock, and is very clean. Upon arrival, I promptly pulled the ni-cad battery, although it showed no signs of corrosion. I've installed a Intel 486DX2 66 CPU and RAM from a 486 board with damaged traces from a leaky ni-cad battery. I've configured the jumpers per the manual for the CPU type and RAM. But I'm not getting any POST codes on a POST card, just dashes. No beeps from the speaker either. With an oscilloscope, I've confirmed clock output from the clock chip. I can also see activity on data and address lines with the scope. I've since learned after purchasing it that this board likely has fake CACHE SRAM chips as they are labeled 'WRITEBACK' in big letters. But these shouldn't keep it from POSTIng, right? Does anyone have experience with these boards? Any thoughts on what to try next?
