TITLE :Always IN-2000 BIOS Versions Change Switch Functionality
PRODUCT :Windows NT
PROD/VER:3.10
OPER/SYS:WINDOWS
KEYWORDS:
--------------------------------------------------------------------------
The information in this article applies to:
- Microsoft Windows NT operating system version 3.1
- Microsoft Windows NT Advanced Server version 3.1
--------------------------------------------------------------------------
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.
The IN-2000 SCSI card is manufactured by Always Technology, a vendor
independent of Microsoft; we make no warranty, implied or otherwise,
regarding this product's performance or reliability.
