Ifo you absolutely must run something old, yet don't want to deal with the complexities of modern emulation: https://www.ebay.com/itm/191322319264 - drivers, whatever is needed, likely to be included on floppy. Ask seller. Not sure what tbe form factor it is. Who cares, nail it to a board or the wall. https://www.ebay.com/itm/283869740055 - obviously a lot faster. 2nd cpu isn't necessary or necessarily beneficial, but it is mandatory (says me, don't be a plebe). Unlike the Intel S5000 series serverboards, this bad boy has a FLOPPY connector. Should boot dos. But I haven't owned 1 yet. Can't remember if I even tried to boot my s5000vsadimmr4 or whatever I had from a dos loaded boot cd. Just can't. But my board did boot Windows 2000. Not too shabby. No drivers or i/o plate with this though. Drivers for Win2k are on tne net. I even foumd a manual I think. Check with me if you have need. The Intel boards have support for Win2008. NOT this board afaik. If that matters to you. Serverboards of this gen/chipset have steemy hot ram. You can nail this to the wall also. But have a desk fan to keep it all cool.
