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.
