Need better driver for SCSI controller

I keep getting error messages when starting up like could not load or run misinfo.exe specified in the WIN.INI file. So I checked device manager and found a yellow mark against the SCSI controller. It indicates that it needs a better driver for the HP EPST parallel SCSI adapter. I tried to find one internally but, it wasn’t acceptable( the yellow mark still there). Where can I find one that’s better?
