Once you download it insert a blank floppy or one you a prepared to lose data of into your floppy drive which i assume you have as you mentioned a bood disk. If you have anewish sounfd blaster card you may need those drivers for sound. Then use the file to make your disk by clicking on it (the first file) and thjen if nessicary extract the sondblaster drivers to your boot disk. Get them here.

Hopefully you should now have a working boot disk. Also for the sound drivers i for got if they have the coding needed for loading already on the bootdisk. If they dont you will need to add the sound driver if you needed it to your config.sys and autoexec.bat . Right lastly dont forget to reply about how you go.
