# qlw(4)

## NAME

**qlw** – QLogic ISP1000/1020/1x40/1x80/1x160 SCSI controller

## SYNOPSIS

**qlw\* at pci?** **qlw\* at sbus?**

## DESCRIPTION

The **qlw** driver provides support for QLogic Ultra Wide SCSI host bus adapters using the ISP1000, ISP1020/1040, ISP1080/1240/1280 and ISP10160/12160 chips.

**qlw** provides no ability to configure an adapter's parameters at runtime; all configuration must be done prior to booting OpenBSD.
