[comp.sys.ibm.pc] 286 -> 386/386sx motherboard upgrade

akm@spencer.cs.uoregon.edu (Anant Kartik Mithal) (02/09/90)

A number of people have mentioned that they upgraded their
motherboards, and I have a question in relation to that. How concerned
does one need to be about the speed of the cards plugged in to the
machine right now? To be more specific, if I take the cards (drive
controller, video, serial/parallel, but not memory) out of a
12 MHz AT, and plug them into a 386/386sx motherboard, can I expect
them to work?

Any other things that future upgraders need to be concerned about?

Also, has anyone upgraded an XT to a 386?

thanks for any info

   The standard speed for an AT I/O bus is 8 MHz, and most clones
obey this; I would imagine that 386SX and DX boards also use this
speed so that you can plug in standard cards, although many of the
newer cards will run at higher speeds.  So you _should_ be okay
taking the cards out of your AT and plugging them into a DX or SX
board.
