orm(4)

orm4

Isa i/o space option rom(s) driver

Usage

orm is automatically included on all systems that have an ISA bus.

Overview

The driver scans at boot time the ISA I/O memory space for option ROM(s) and claims them. Other drivers are thus precluded from using ISA I/O memory that is on top of an option ROM.

Bugs

Due to the implementation of the resource manager, other drivers cannot attach to the option ROM address range.
