Put all the files on a floppy disk.
This driver is for the Gravis Ultrasound ISA card. After installing the sound card in a spare ISA slot and switching your PC back on, point find new driver to the A drive where the "UltraPnP.inf" file is.
I apologise but it has been a while since I last used this driver so I'm not sure at which point you should double click on the "setup.exe" file.
There wasn't much in the way of instructions for installing this driver as I remember, so a little trial and error should get you by.
Note Burn this driver onto a CD in a folder named - "GRAVIS_PNP" and it should install much easier.
