Well, try to bug Adaptec to get some docs first. Then, have a look into the existing driver, and try to spot what needs to be fixed. There's also room for improvement, i think. The driver sources speak about the intention to also implement DMA some day, but this apparently never happened. Don't forget that there's a section about kernel debugging in the handbook -- i assume you'll need it. ;-) If you can spare a second machine for debugging work, remote gdb is really cool. Single-step your kernel in Emacs, gdb in one window, and the source in the other one, if you want. :-) -- 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. ;-)
