It's a whole lot better to give the exact output. For example: # cd /dev # ./MAKEDEV wcd0 (All sorts of fireworks here) In any case, MAKEDEV is only a script that creates device nodes. It will work the same whether you actually have the device connected or not. > It appears to almost work but lacks a direct memory access channel no. > How can I supply this? I don't think ATAPI uses DMA. Does anybody else out there know? > MAKEDEV wcd0 may not work due to lack of drq (dma?) problem? No. As I said, MAKEDEV has nothing to do with the real hardware. Greg
