ST506/412 or SCSI controller

A.L.F. 2 is a general hard disk driver software with 16 different hardware versions based on it
supports processor cards and does some optimizations for the better processors
handles drives up to 1 GB only
Model 1:
- only ST506/412, either MFM or RLL
- cannot autoboot - by making the driver reset resistent, rebooting off hard disk is possible
- the Zorro II version is half length (only a Zorro - XT adaptor board), the metal hard disk mounting frame is optional
Model 2:
- ST506/412 (either MFM or RLL) or SCSI
- autoboot ROM - autobooting requires at least Kickstart 1.3
- the Zorro II version is full length and has place for mounting a 3.5" hard disk
if a Model 1 and a Model 2 controller are installed in one Amiga at once, the Model 2 controls the Model 1 (autobooting is possible on both controllers)
the 16 versions of A.L.F. 2:
- A2000 MFM - Model 1 & 2
- A2000 RLL - Model 1 & 2
- A2000 SCSI - only Model 2
- A500 MFM (without casing) - only Model 1
- A500 MFM (with casing) - Model 1 & 2
- A500 RLL (without casing) - only Model 1
- A500 RLL (with casing) - Model 1 & 2
- A500 SCSI (with casing) - only Model 2
- A1000 MFM (without casing) - only Model 1
- A1000 MFM (with casing) - only Model 1
- A1000 RLL (without casing) - only Model 1
- A1000 RLL (with casing) - only Model 1
the A500 and A1000 versions connect to the side expansion port
those without case have no passthrough connector, the others have
