Help, I am getting a TRAP 000D when ever two DMA devices like HD & FD are used at the same time, like swap while reading fd, or copy FD to a file on HD. I have tried setting DMAEXCEL to both 1 & 0, it seems to make no difference. CACHE Enable/Disable also no effect. The processor is a 486 (no brand/Tiwan) using an 82C206 for DMA and 82C481 & 82C482 for Cache control. Any help appreciated, quick please. John Watson ...!rutgers!carssdf!usenet
