NAME

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.
