I am thinking of replacing my 10MHz 286 motherboard with a 25MHz 386 and I'm worried that my ATI Wonder won't be able to operate at that speed. Does anyone out there know - or even have a guess? (It's about 1 year old with 512K).

Does anyone out there know - or even have a guess? I'm not sure that I know what you are talking about. The bus speed on the 386 will be the same speed as the 286 ie 8.33 MHz. If it will help I've got this card on on my 386/25 w/ 64k cache and it runs at ~23k chars/sec with the bois in RAM. Hope this helps.

Does anyone out there know - or even have a guess? ---------- The video card only cares about the bus speed. I'm running the bus on my Micronics mb at 12.5MHz with an ATI VGA1024 (I had a VGA WONDER) and have had no problems with either card. In fact, Gateway 2000 guaranteed me that all the cards supplied with their system could run at the higher bus speed. Ken

I believe the clock speed (10 or 25 MHz) isn't significant. What counts is the bus speed. Every 386 I've worked on can run the bus at 8 MHz, which would be no problem for your VGA card.

What determines which bus speed is used? How does one change the bus speed (the posting implies one can select it -- at least on his Micronics motherboard)? Can one tell what the bus speed is by visual inspection (a crystal marked with a frequency, perhaps)?

The most standard bus speed for an AT-bus machine seems to be 8 MHz, just like IBM defined it with the 8 MHz AT. I work primarily with HP Vectra 386 systems with 16 MHz, 20 MHz and 25 MHz clock speeds. Each of these machines has two bus speeds. The choice is made with a DIP switch on the processor board. This is clearly documented in the hardware manual "Setting Up Vectra RS". The factory default bus speed is 8 MHz Async. The optional choice is half the clock speed, synchronous. For example, a 25 MHz system's optional bus speed is 12.5 MHz. This is one of those times when you need a good hardware manual.

That's an interesting claim since there is no standard spec for operation at such a speed. --
