Drive not ready

hi!
i have a quantum fireball scsi drive and i try to load windows nt 4.0 on it. i start the setup with the 3 setup diskettes using the floppy drive. during the setup i locate my drive controler and then it ask for any other support for mass storage devices. i skip that step coz i donot have the driver for the drive but when it comes to load the operating system ,it does not read the drive and the message "drive is not accessible" is displayed. where can i get the driver from? or is it the termination ? please help.
thanx
