Yes, DRIVER.SYS will work. But it loads an entirely unnecessary device
driver into the scarce 640K real estate. It also puts the drive at a
different letter. While most people will not run out of drive letters,
some demented software (including certain MICROS~1 OS installs) refuses to
accept any but A: and B: for the floppy letters!

By running a BIOS other than IBM's, it is possible to use DRIVPARM to
merely set the drive parameters to their correct values.
