Its pity very few boards support FSB speeds between 40 and 50 MHz, I think some revisions of the Asus PVI-486SP3 can do 48 MHz but the PCI clock will still be high enough to mess with the built in I/O controllers, 44.5 MHz would be more useful. Its easier with the older ISA and VLB motherboards with a crystal that controls the FSB.
My Lucky Star LS486E boards only support 1/1 and 1/2 PCI dividers which makes the 50 MHz FSB setting more or less useless. I have another very interesting PCI board I need to tinker with though which could have the 2/3 divider.
Yeah but wouldn't lowering the FSB take most of the fun out of it? Come on, the idea of having a bus running @ 40 or even more MHz is fantastic! Going back down to 33, playing around only with the CPU frequency, is a little boring, but this is entirely subjective, of course.
Guys, I think we all need a modern manufacturer producing a modern 486-compatible (Socket 3 I'd say) motherboard, with PCI, VLB, and ISA slots, very well tuned to handle any kind of frequency on the FSB, from zero to 66 MHz. Then the only problem would be the tolerance of the cards, but the entire CPU-MOBO problem would be solved.
Ah, and of course with 1024K of the best possible L2 cache, still modern-currently built.
