Ok so I decided to put a pentium I together. I picked up a board in my ecycling business. Looked thru and found an isa video card. I like this board as it has the 72 pin and newer simms. Aswell as the 20 pin power and the older style. Isa and pci slots. Anyway I have no idea how to power it on? I was able to get it to boot up including memory count and all the way to CMOS battery error. I didn't want run it too long without a CPU fan. I really don't know what I was doing as I was just moving around the wires labeled hdd led and reset switch and turbo led. I played around some more and got the fan to spin a couple times and no video. This freaked me out as i thought i may fried something.Let it sit and got it to boot again by moving the wires around. So I left it at that. Maybe I need to look harder but shouldn't there be two pins for a power switch? Also can I run a black fiber pentium mmx chip in this board? Also what is the max ram? I have a million other questions but just one more for where can I get an older style case? I will post some pics in the morning. Thanks.
