- Technical Advisory Note 002 28 July 1989 revised 9 August 1989
- Microsoft and Logitech BUS Mouse
-
- We have been advised the I/O address (Port) range for the Microsoft BUS
- Mouse is 220-24F. An example configuration for VMOSCONF of such a mouse
- using IRQ 5 would be:
-
- Configure Port Create MOUS 220 24F Mouse
- Configure VDD Create MM Mouse
- Configure Port Up MOUS
- Configure IRQ Up IRQ5
- Configure Port Attach MOUS MM
- Configure IRQ Attach IRQ5 MM
- Configure VDD Mode MM fOreground
- Configure VDD Up MM
-
- The Logitech BUS Mouse is similar. Its I/O (Port) range is 23C to 23F. An
- example configuration using IRQ3 would be:
-
- Configure Port Create MOUS 23C 23F Mouse
- Configure VDD Create LM Mouse
- Configure Port Up MOUS
- Configure IRQ Up IRQ3
- Configure Port Attach MOUS LM
- Configure IRQ Attach IRQ3 LM
- Configure VDD Mode LM fOreground
- Configure VDD Up LM
-
- Note that the IRQ assigned must not be used by any other resource. Some
- common IRQ assignments follow. If you have the indicated resource in your
- 386, then the associated IRQ is UNAVAILABLE. Any IRQs not listed in the chart
- below are commonly unavailable.
-
- -------------------------------------
- All AT BUS systems (reserved) IRQ2
- COM2 serial port IRQ3
- -------------------------------------
- COM1 serial port IRQ4
- LPT2 parallel port IRQ5
- -------------------------------------
- XT hard disk controller IRQ5
- -------------------------------------
-
- IRQ2 is used as the expansion interrupt on AT BUS systems. Some components do
- use IRQ2, however. These are commonly LAN adapters. For these, Vmos/3 maps
- IRQ2 to IRQ9. If you have to select IRQ2 on an adapter, define it as IRQ9
- under Vmos/3. See TAN003 for more information.
