Mmm, don't think so. As phil22 mentions, a reinstallation of NT4 should reformat the drive, causing any drivers (or anything else) on the system to be lost. All you'll have is the installation, and if you don't load drivers, NT will pick it's own (though it doesn't have many), or use the default (i.e.---often low-performance versions). Most unrecognized devices will show up with the "dreaded" yellow exclamation point in Device Manager for things that it can't figure out.
While sites like DriversMax and DriversGuide have many drivers available, it's better if you can find the original disks (or CD's) they came with for NT4, or find a correct driver from the manufacturers' website (assuming they still exist). I've had a good deal of problems with both the above "drivers-sites", especially when it came for NT drivers...
