This is a multi-part message in MIME format. --------------11C205ACD5FC21102DF1DFBF Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit Howdy, I recently added an Adaptec SCSI card (Adaptec 2940 Ultra SCSI adapter) to my system. Since then I can no longer run anything that accesses the sound card (AudioPCI ES1371) without winning a Fatal Trap 12. A friend of mine suggested that the SCSI card and the sound card may be trying to access the same DMA channel. However, I am not sure how figure out which DMA channel is being used for either device. Can anybody tell me if this theory holds any water? And if so, do you know how I can modify things to make this work again? Thanks!
