TN.108.AddDrive DrvrInstall and - AddDrive, _DrvrInstall, and _DrvrRemove are used in the sample SCSI driver in the SCSI Development Package, which is available from APDA. This Technical Note documents the parameters for these calls. Changes since March 1, 1988: Updated the _DrvrInstall text to reflect the use of register A0, which should contain a pointer to the driver when called. Also added simple glue code for _DrvrInstall and _DrvrRemove since none is available in the MPW interfaces.
