Reading did though. > I've had similar problems with 3.0-SNAP 970807. However, I did not have this problem with 2.1.6 or 2.1.7, from which I upgraded. I posted this about a month ago and one of the core team (J'org) is aware of it, but didn't have any system to test it on. I'm running on interrupt 9/2 at the moment. wt0 at 0x300-0x301 irq 9 drq 1 on isa I have an clumsy time reading debug messages, as I'm running a fixed-freq monitor and it works only in X. I'll try to get an old monitor and hook it up and save the debug messages. -- Jim Durham <Television Engineer-Unitel Mobile Video, Pittsburgh> <Computer Consultant/Hobbyist> <Amateur Radio: W2XO> <Web:http://www.w2xo.pgh.pa.us>; <Packet:W2XO@W2XO.#SWPA.PA.USA.NOAM>
