This is the motherboard I use for bench testing most of my ISA, VLB, and PCI cards under DOS and Windows 3.1.
I'm really pleased with this motherboard and its versatility, but I've always been a little confused by the CPU selection jumpers. Here's the part of the manual that addresses the matter.
Right now, I'm using an Intel 486SX2-66, and there are two "Resister Packs" (like a long, skinny 10-pin thing), one on S4 and one on S6. It works perfectly. However, I want to test some AMD 5x86 and Cyrix 5x86 CPUs, and I'm not sure what the difference is between S4 and S7 when it comes to the AMD 5x86. Or for the P24D I'm running now, for that matter, which seems to be fine with S4 and S6. I assume that both packs have to be inserted.
Would you use S4 or S7 for an AMD 5x86-P75? Or any idea what the logic is behind the combo of the two packs?
Here are the other jumper settings that have to do with the CPU.
