- 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.
