I must say that under NetBSD 1.2 the system reports "lpt0: out of
paper" messages on the console, without having a printer connected, so
I suspect some abberant hardware is generating interrupts. But why is
thid redirected to IRQ 7 here?? Does it have something to do with this
IOCHCK signal?? Have you got some pointers to documentation about
these matters??

Many thanks
