NAME
     asr -- driver for Adaptec I2O based SCSI/ATA host bus adapters

SYNOPSIS
     device asr

DESCRIPTION
     The Adaptec asr driver provides access to disks and disk arrays con-
     trolled by	I2O based host bus adapters and	SmartRAID SCSI RAID adapters
     through the standard SCSI disk da(4) interface.

     The supported adapters provide 64 bit PCI,	Compact	PCI, Zero Channel PCI,
     and up to four channels of	Ultra2,	Ultra 160, or Ultra320 SCSI, or	two
     channels of 1GB Fibre.  All support RAID-0, RAID-1, RAID-10, RAID-5 and
     RAID-50 arrays.  All SCSI target types are	supported.  For	the ATA	based
     controllers, one IDE drive	per channel is supported.  Hot-swapping	of IDE
     drives is not supported at	this time.

     All host bus adapters must	be configured before they can be used with any
     operating system.	Please contact Adaptec directly	to obtain the latest
     information on configuration utilities for	the adapters.  Currently there
     are both a	Motif based GUI	configuration utility and a CLI	based configu-
     ration utility available from the Adaptec Web site.  The cards and	arrays
     can also be configured via	the BIOS based configuration tool (SMOR).

     +o	 Adaptec SmartRAID PM3754
     +o	 Adaptec SmartRAID PM3755U2B / SmartRAID V Millennium
     +o	 Adaptec SmartRAID PM3757
     +o	 DEC KZPCC-AC (LVD 1-ch, 4MB or	16MB cache), DEC KZPCC-CE (LVD 3-ch,
	 64MB cache), DEC KZPCC-XC (LVD	1-ch, 16MB cache), DEC KZPCC-XE	(LVD
	 3-ch, 64MB cache) -- rebadged SmartRAID V Millennium

NOTES
     The ATA based controllers present their devices as	SCSI-like devices via
     CAM.  For IDE drives attached to these cards, a subset of standard	SCSI
     commands and mode pages are understood via	translation performed in the
     card's firmware.

HISTORY
     The asr (Adaptec SCSI RAID) driver	first appeared as the dpti2o driver
     under BSDi	BSD/OS 3.2, then under FreeBSD 2.2.8 and was ported over to
     the CAM layer represented in 4.0.

     The asr driver was	kindly donated by Adaptec and is maintained by Mark
