Driver for the Adaptec SCSI host adapters based on the AIC-7770 controller:
- AHA-2840QVL - VESA local bus
- AHA-2842VL
- AHA-2740/2742 - EISA
CONFIG.SYS Information
BASEDEV=AIC7770.ADD <parameter>
Universal Parameters:
- /ET - Allow embedded targets. This parameter indicates that the ADD should assume that all targets have more than one logical unit (LUN) defined.
- /!ET - Do not allow embedded targets (DEFAULT). This parameter indicates that the ADD should assume that all targets have only one logical unit (LUN) defined.
- /V - Load driver verbosely. This parameter will display the driver name as well as the version number and Adaptec copyright if the driver loads successfully. Information on all targets found in the system will also be displayed.
- /PCIHW - Enables driver to access PCI configuration hardware registers. This switch is implemented because in some PCI systems, accessing PCI configuration space through PCI BIOS function calls causes problems. This switch is enabled by default. New with Version 3.02
- /!PCIHW - Disables the PCIHW switch. This parameter will cause the driver to access the PCI configuration space through PCI BIOS function calls. New with version 3.02
General Unit Parameters:
- /I - Ignore the specified adapter. This allows another driver to share the adapters that the ADD would normally use.
- /DM - Enable DASD manager support (DEFAULT). This parameter allows OS2DASD.DMD to control the specified target(s) if they are identified as DASD (hard disk) devices.
- /!DM - Disable DASD manager support. This parameter prevents OS2DASD.DMD from controlling the specified target(s).
- /SM - Enable SCSI manager support (DEFAULT). This parameter allows OS2SCSI.DMD to control the specified target(s) if they are identified as NON-DASD SCSI devices. All SCSI hard drives will be controlled by OS2DASD.DMD.
- /!SM - Disable SCSI manager support. This parameter prevents OS2SCSI.DMD from controlling the specified target(s).
- /TAG:n ... n=1-16. - Specifies the maximum number of tagged commands for all target devices on the host adapter (1-16). A value of 1 disables tagged queuing. The maximum number allowed is 16. (The default is 8.)
- /UR - Enables reporting of under runs (DEFAULT).
- /!UR - Disables reporting of under runs.
