W2k will install without smartdrv.exe, but file copying will take forever. Just find smartdrv.exe, copy it to your boot floppy if it's not already there, and run it from the A:\ prompt before you install w2k. If your drive's on an ATA100 controller, you've got to load the drivers (from a floppy) at the start of install - one of the screen messages is if you want to load a driver to press a function key (F6, as I recall) - - or you could install w2k on IDE33, install the ATA100 drivers in w2k - do it once for each ATA100 channel - and later move the drive to ATA100 (as long as the drive letter doesn't change you'll be OK).
