- I should have mentioned this in the last post: changing the I/O bus speed
- can have an effect. However, like setting the DMA rate on the 1542B, there is
- a point beyond which you will be plagued by data corruption. My 386/40 will
- let me set my I/O bus as high as 20 MHz, but it is very obviously flakey when
- I do so. At 13 1/3 MHz, it works fine. At work I have some 386/33s tuned to
- operate their I/O bus at 16.5 MHz; the VGA cards (from ATI, Oak, and Trident),
- I/O cards (generic crud), and ethernet cards (Katron) work fine at that speed.
-
- You should back up first and test thoroughly before walking away from a
- system you've twiddled in this way.
