Model: I 30
Operating System: Windows 3.1 (Note: might work with other versions of this os.)
On a Win3.1 system, run INSTALL.BAT and it'll put the driver in the right place under the WINDOWS diretory. It'll also create an /ETC/SCANNER directory with sdr2aspi.sys in it.
I'm uploading this because it isn't here(!) and other peoples' disks may have been corrupted over time as well (and some people may still be running on some old 486s).
