a question only for the win98 pros!!!

I have a dilemma. I currently have windows NT on a pentium 166 on my pc upstairs. But i want to play my old win 98 games on it. I have a created boot-disk and a copied win98 setup disk ( in case i lost the original which i did). I restart the pc with the boot disk in and I see a few dos lines containing banana and cd-rom drivers and then it takes me to a line reading driver=R and it leaves me at the promopt A:\. what do i do to tell it to install from the floppy? i will havethe upmost respect for whoever solves this problem. PS. I have also copied the win98 disk to my hard drive.
