A2091-40/A2091
The A2091 Hard Disk Controller is an internal SCSI controller card and expansion
memory unit for the Amiga 2000. The A2091-40 consists of an A2091 and a Quantum
40-megabyte SCS! hard disk. Installing a A2091-40 in your Amiga 2000 converts
it Into an Amiga 2000HD. If you have an Amiga 2000HD or an Amiga 2500, you
already have an A2091-40 installed.
The A2091 connects to an expansion slot inside the Amiga and comes with a floppy
disk containing all the software required for operation.
The A2091 includes the following features:
Sockets for 512KB, 1MB, or 2MB of fast random access memory (RAM) chips
Direct Memory Access (DMA) for fastest possible operation
Internal and external connectors for the use of Small Computer Standard
Interface (SCSI) expansion devices
© Autoboot ROMS to allow you to boot your system from the hard drive, if you
are using Kickstart 1.3
The A2091-40 package includes a Quantum ProDrive 40S (40-megabyte SCSI hard
disk), a 50-pin ribbon cable, and all the parts required to mount the hard disk and
controller card.
With the addition of the A2091-40/A2091, your system will still operate normally
using the floppy disk drive.
NOTE: To obtain the full potential of the A2091, you will want to have the Kickstart
1.3 ROM installed in your Amiga 2000. With the Kickstart 1.3 ROM you will be able
to automatically boot your system from the hard disk, rather than from a floppy disk.
You can determine whether your Amiga has Kickstart 1.2 or 1.3 by starting your
‘system without a disk in the floppy drive. The screen will show a hand holding a
Workbench disk, with the version number below it. If the version number Is 1.2,
your Amiga is using Kickstart 1.2. Please see your Amiga dealer conceming the
ROM upgrade. If the version number is 1.3, your Amiga already has Kickstart 1.3.
