# orm(4)

ISA I/O space option ROM(s) driver

## NAME

**orm** – ISA I/O space option ROM(s) driver

## SYNOPSIS

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

## DESCRIPTION

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.

## AUTHORS

This manual page was written by Nikolai Saoukh ⟨*nms@otdel-1.org*⟩.

## BUGS

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