Perhaps I should try running the > game from a ramdisk.. hmm.. Am I to get this right, "Secret of the Silver Blades" runs the data from the disk to memory than immediately to the SB? SB uses DMA channel 1, which does not conflict with any DMA unless you have a rare built-into-motherboard disk controller. The problem I could see is the 2 DMA (of different channels) fighting for the bus. If that is the case, the software maker should take care of DMA arbitration. Call the software maker, maybe they already have a fix! E. Teng Ong (ong@d.cs.okstate.edu)
