   Last minute #DOScember entry, if fiddling with BIOS stuff counts... A while ago I bought this Soyo 386DX mainboard with a 486DLC + FPU in it from evilBay, with the intent of reproducing one of the quirky and weird setups of my youth. But that board had Mr. BIOS in it, while this thing came with AMI BIOS.

   So I bought a handful of 27C512 EPROMs, burned a matching Mr. BIOS image thanks to the preservation efforts of people on Vogons.org, a quick chip swap and here we go. 😍
