To install the IN-2000 AL1IN2.ADD OS/2 2.x driver, you will need to copy the AL1IN2.ADD driver file to the IBM OS/2 diskette labeled "DISK 1" and modify the CONFIG.SYS on DISK 1 to load the driver. A sample CONFIG.SYS called CONFIG.OS2 has been zipped in with this file to show how the driver should be loaded. The port address and interrupt arguments in the driver load line should match the actual settings of the IN-2000. !!! This is the second BETA release of the IN-2000 OS/2 driver !!!
