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.
