There's too few interest, nobody of the ``classic'' hackers seems to have the hardware and/or time to do it. Of course, you are welcome to imporove it. :) You've got at least two of the missing things, hardware and interest. It looks that the guy who wrote the driver started to think about DMA, but didn't finish it ever. -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
