486 ;( install probs!

I got an old 486 from a friend to fix/ it had win 3.1 on it and i want to upgrade to 98! I tried to hook the drive up to my pc- but its so old school that i had to put the power cable from floppy to the HD to power the sucker--I dont know the jumper seting either, its an old TEAC SD-3105 ...its not even clear on how big the sucker is either...
any help would be appreciated
