- 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.
