beside my pmax box, I got a ix86 box also running NetBSD 1.5.2 on it.
Dmesg showed, that something is wrong with dma busmastering and that
interrupts are lost. So I decided to disable dma access and go down to
PIO mode 4. That's secure, I guess. Does somebody know how I can achieve
Thanks in advance.
