Well, not quite but... This past Sunday I moved by BSD/386 (beta) system to a Cyrix 486SLC-based machine. This appears to be a generic 385sx-25 motherboard, but with a 486SLC-25 chip. I also installed a Cyrix 387sx FastMath that I had from another machine. The results: Everything appears to work correctly and is very stable. Initial performance results were very bad as I had forgotten to enable the on-chip cache from the BIOS. (BSD/386 thought it was an 8 mhz 80486 and it dhrystoned like an 803sx-16.) Turning on cthe cache, however, produced results that were about 1/3 faster than I would have expected with an 80386sx-25 (approx. 9000 dhrystones/sec). Depending on prices in your area, though, you may want to compare the cost of a 386-40 vs. that of the Cyrix 486. <<<John>>>
