  • 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
