SUMMARY
The Always IN-2000 SCSI adapter has switches that allow you to set the IRQ, I/O port address, and so on, but the Windows NT Adapter Card Setup Help file (NTCARD.HLP) documentation for the switch settings is applicable only if your IN-2000 card has BIOS version VCN:1.02.



MORE INFORMATION
There are several different BIOS versions available for the Always IN-2000 cards, and each of these BIOS upgrades changes the functionality of one of the hardware switches (SW1-8).

The following settings are consistent across all BIOS versions: SW1-1 SW1-2   Segment Address -- off   off     C800h-CBFFh on    off     D800h-DBFFh off   on      D000h-D3FFh on    on      BIOS DISABLED

SW1-3 SW1-4   I/O Port Address --- off   off     220h-22Fh on    off     200h-20Fh off   on      110h-11Fh on    on      100h-10Fh

SW1-5 SW1-6  SW1-7  Interrupt (IRQ)

off   off    off    15 off   on     off    14 off   off    on     11 off   on     on     10 on    ---    ---    DISABLED

SW1-9 Floppy Controller

off   DISABLED on    ENABLED

SW1-10 is not used. However, the functionality of SW1-8 changes, depending on which BIOS version you have.

If you have BIOS version 3.xx (these are earlier versions), SW1-8 should be left off.

If you have BIOS version VCN:1.02, SW1-8 controls the support of synchronous data transfers. If this switch is off, the data transfers are asynchronous; if it is on, they are synchronous.

If you have BIOS version VCN:1.03, SW1-8 controls the support of multiple drives. If this switch is off, multiple drive support is disabled; if it is on, multiple drive support is enabled.
