unixbp —
Unix Backplane driver
SYNOPSIS
unixbp0 at ioc0 bank 6
DESCRIPTION
The
unixbp driver controls the interrupt-masking hardware on
the expansion-card backplane of certain systems. This hardware gives
NetBSD the ability to selectively block interrupts
from particular expansion cards, and to determine which cards are currently
generating interrupts by examining a single register.
