The layered device driver architecture has made it possible to easily support IBM and non-IBM disk and SCSI controllers. At the device management driver level, OS/2 V2.0 supplies two drivers:
OS2DASD.DMD
OS2DASD.DMD will always be loaded. OS2SCSI.DMD is only needed when a SCSI adapter is present.
OS/2 V2.0 provides a number of adapter device drivers (ADDs) which are specific to the adapter or adapters installed in the system. At installation time, OS/2 V2.0 can in most cases sense the adapters installed and will then load the necessary ADDs and include the necessary BASEDEV statements in the CONFIG.SYS. ADDs are currently available for all IBM disk devices and some selected non-IBM adapters. See the OS/2 V2.0 Online Command Reference and the README file, which comes with OS/2 V2.0, for details of the supported adapters. The README file should always be consulted when using a non-IBM SCSI adapter.
At general availability of OS/2 V2.0, support was available for IBM, Future Domain** and Adaptec** SCSI adapters.
Shipped with OS/2 V2.0 is a generic disk device driver IBMINT13.I13. When specific support is not provided for a particular adapter, it should be possible to use this driver.
