- AIC7xxx Driver for Linux
- April 15, 1996
-
- Introduction
- ------------------------
- The AIC7xxx SCSI driver adds support for Adaptec (http://www.adaptec.com)
- SCSI controllers and chipsets. Major portions of the driver and driver
- development are shared between both Linux and FreeBSD. Support for the
- AIC-7xxx chipsets have been in the default Linux kernel since approximately
- linux-1.1.x and fairly stable since linux-1.2.x, and are also in FreeBSD
- 2.1.0 or later.

- U - Ultra SCSI, transfer rates up to 40MB/s.
- D - Differential SCSI.
- T - Twin Channel SCSI. Up to 14 SCSI devices.
-
- AHA-274x - EISA SCSI controller

- AHA-29xx - PCI SCSI controller
- AHA-394x - PCI controllers with two separate SCSI controllers on-board.
- AHA-398x - PCI RAID controllers with three separate SCSI controllers
- on-board.
-
- NOTE: The AHA-2920 is NOT a AIC-7xxx based controller, and is not
- handled by this driver.

- People
- ------------------------
- Justin T Gibbs gibbs@freefall.FreeBSD.org (BSD Driver Author)
- Dan Eischen deischen@iworks.InterWorks.org (Linux Driver Co-maintainer)
- Dean Gehnert deang@teleport.com (Linux FTP/patch maintainer)

-
- Special thanks go to John Aycock (aycock@cpsc.ucalgary.ca), the original
- author of the driver. John has since retired from the project. Thanks
- again for all his work!
-
- Mailing list
- ------------------------
- There is a mailing list available for users who want to track development
- and converse with other users and developers. This list is for both
- FreeBSD and Linux support of the AIC7xxx chipsets.
-
- To subscribe to the AIC7xxx mailing list send mail to the list server,
- with "subscribe AIC7xxx" in the body (no Subject: required):
- To: majordomo@FreeBSD.ORG
- ---
- subscribe AIC7xxx
-
- To unsubscribe from the list, send mail to the list server with:
- To: majordomo@FreeBSD.ORG
- ---
- unsubscribe AIC7xxx
-
- Send regular messages and replies to: AIC7xxx@FreeBSD.ORG
-
- Command line options
- ------------------------
- "aic7xxx=no_reset" - Eliminate the SCSI reset delay during startup.
- Some SCSI devices need some extra time to reset.
-
- /proc support
- ------------------------
- The /proc support for the AIC7xxx can be found in the /proc/scsi/aic7xxx/
- directory. That directory contains a file for each SCSI controller in
- the system. Each file presents the current configuration and transfer
- statistics (enabled with #define in aic7xxx.c) for each controller.
-
- Thanks to Michael Neuffer for for his upper-level SCSI help, and
- Matthew Jacob for statistics support.
