You could look up your hardware drivers from the manufactures sites then put them on a cd or floppy, why don't you make a back up of your system with an imaging software and store it on a partition instead then you have all your drivers intact.
Which do you want help with, making a image back up or your drivers, if it is your drivers then you will need to find out what hardware you have on your system them go to the necessary websites and look up your hardware and download the required drives, then burn them onto a disc.
Is this for a PC? if so have you got a motherboard disc or did it come with any?
ok have a look here http://sourceforge.net/projects/drvback/
that should do it all for you, although if you did want to do it all manually then download everest home edition or pcwizard and find out what chipset / graphics etc you have google and find the driver.
So you did nor get any software discs with it? does it have a recovery partition with it? if not get make a back up partition then use Norton ghost or acronis true image to copy your entire drive then store it on the partition, never defrag the back up partition though.
