I don't think it's got an `enhanced mode' entry in the config. Once i'm back at home, i can also mail you the EISA cfg file, should nobody have done it yet. My Bt742A is working with: ISA DMA emulation disabled; the non-default value for the interrupt trigger method (edge triggering, i think); a bus clock as close to 8 MHz as possible. Burst mode does work, too. -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ Never trust an operating system you don't have sources for. ;-)
