Actually GenericMacSCSI is supposed to have a "generic" (meaning non-Apple) Macintosh SCSI driver stored as a couple of resources (one contains the driver and one contains information about it). There is no point in making a copy of ADU & call it GenericMacSCSI in the Drivers folder, because ADU contains only the Apple driver, not a generic driver, and it will already load this resource from its own resource fork anyway! The best solution is to answer ADU's alert by saying Yes, you want to use your drive on a Macintosh; I think it will create the APPLE_DRIVER partition. Then use whatever utility came with your Macintosh hard drive (Apple or non- Apple) to "update" the driver. If your 3rd-party utility is unwilling to update the driver unless the contents of the APPLE_DRIVER partition already "looks" like a valid driver, then you might have a problem. In that case, you could make a GenericMacSCSI file containing the $4D61 and $5E72 resources from ADU (rSCSIDrvr and rSCSIDescDrvr), only change the resource IDs from 1 to 2, so they'll get loaded for a "generic" drive. (I don't know whether there are 3rd-party utilities that would make you resort to this, or not.) -- David A. Lyons, Apple Computer, Inc. | DAL Systems Apple II System Software Engineer | P.O.
