I have a similar problem on a 486 card. The card with the Intel/Zymos
80..31 80..32 2 chip set is OK (I forget the whole number). Another
486 that has its own 128K cache using the "OPTI" chipset and an 80C206
peripheral/DMA/CMOS chip crashes whenever I use 2 dma devices at the
same time, like floppy or archive tape in combination with hard disk.
The hard disk is a 600meg ESDI with 4 Meg cacheing controller by
Consensys (Toronto Canada). Panic, Double Panic etc.. I am trying
things like a different 80c206, or different 80c206 vendor, Semens and
Chips & Tech. both make it. So far I have only tried Semens. If this
helps you good luck. If you have related info, pls pass on. Incedentally,
other than this minor/fatal flaw it is the fastest system I have ever seen.
This is not in the same league with 386's.
