aha -- Adaptec SCSI host adapter driver SYNOPSIS
To compile this driver into the kernel, place the following lines in your kernel configuration file: device scbus device aha Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5): aha_load="YES" In /boot/device.hints:"isa" DESCRIPTION
This driver provides access to the SCSI bus connected to the Adaptec AHA-154x and AHA-1640 SCSI host adapters. x is 0 for controllers with- out a floppy drive and 2 for controllers that have them. For optimum performance, Adaptec AHA-174x controllers should be configured in enhanced mode and attached via the ahb(4) driver. One device hint entry for every card to be attached by the system is required. Specific values for the port address, IRQ, and DRQ may be specified. If wildcard values are used, the driver will query the device for its current settings and use those. If the port address is a wildcard, the driver consults an internal table of possible port address locations and attaches to the first unattached card it finds. The possible port addresses for this card are 0x330, 0x334, 0x230, 0x234, 0x130, and 0x134. The AHA-1640 is an MCA bus card. Since the MCA bus is a self-identifying bus, no setting of hints is required. HARDWARE
The aha driver supports the following SCSI host adapters: o Adaptec AHA-154xB o Adaptec AHA-154xC o Adaptec AHA-154xCF o Adaptec AHA-154xCP o Adaptec AHA-1640 o Adaptec AHA-174x in 154x emulation mode o DTC 3290 SCSI controller in 1542 emulation mode o Tekram SCSI controllers in 154x emulation mode SEE ALSO

The aha driver was ported by M. Warner Losh from the bt driver written by Justin T. Gibbs. BUGS
The AHA-154xA card does not support residuals on data transfers. As a result, this card is no longer supported. There have been some reports that the AHA-154xB does not work well under heavy load. The AHA-154xCP is a plug and play controller. However, its resources are set using the on-board BIOS and cannot be moved. Failures to attached for this card are often caused when the resources set in the BIOS conflict. BSD

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 controlled 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 configuration utility available from the Adaptec Web site. The cards and arrays can also be configured via the BIOS based configura- tion tool (SMOR). HARDWARE
The adapters currently supported by the asr driver include the following: o Adaptec Zero-Channel SCSI RAID 2000S, 2005S, 2010S, 2015S o Adaptec SCSI RAID 2100S, 2110S o Adaptec ATA-100 RAID 2400A o Adaptec SCSI RAID 3200S, 3210S o Adaptec SCSI RAID 3400S, 3410S o Adaptec SmartRAID PM1554 o Adaptec SmartRAID PM1564 o Adaptec SmartRAID PM2554 o Adaptec SmartRAID PM2564 o Adaptec SmartRAID PM2664 o Adaptec SmartRAID PM2754 o Adaptec SmartRAID PM2865 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 FILES
/dev/asr* Adaptec SCSI RAID control nodes 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. SEE ALSO
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. AUTHORS
The asr driver was kindly donated by Adaptec and is maintained by Mark Salyzyn <>. This manual page was written by Mark Salyzyn and fixed up by Jeroen Ruigrok van der Werven <>. BSD
