To use Catalyst 2.0 with the Apple III and hard disk drives other than the
ProFile, you need to change the driver configuration block of the .CATALYST
driver as follows:

 00  01  02  03  04  05  06  07  08  09  0A  0B  0C  0D  0E  0F  10  11
 --  --  --  --  --  --  --  --  --  --  --  --  --  --  --  --  --  --
 (See notes just below)  00  8F  97  8A  91  93  23  17  17  F6  00  B8

 Notes:

 00 - Slot number
 01-  Unit number
 02 - Type
 03 - Sub Type
 04 - Low Byte, Manufacturer's ID
 05 - High Byte, Manufacturer's ID

For a 10 megabyte ProFile, copy the information in bytes 00 through 05 from the
existing Catalyst hard disk driver configuration block (DCB) of the Catalyst
driver that you are using.  For a 10 MB Profile, the DCB should look like this:

 00  01  02  03  04  05  06  07  08  09  0A  0B  0C  0D  0E  0F  10  11
 --  --  --  --  --  --  --  --  --  --  --  --  --  --  --  --  --  --
slot  00  01  01  23  00  00  8F  97  8A  91  93  23  17  17  F6  00  B8

For a 5 MB Profile, the DCB should look like this:

 00  01  02  03  04  05  06  07  08  09  0A  0B  0C  0D  0E  0F  10  11
