is a great place to acquire drivers for the older hardware.
The biggest problems I ran into when I setup similar to your quest to play my older games was first off finding drivers for the hardware, and secondly remembering all I had forgotten about those older operating systems.
Juggling IRQs to get it all to work smoothly together is an imperative revisit of the old brain matter as CompTIA_rep has already mentioned, what you're after is a challenge, and a lot of fun but frustrating sometimes too!
Good Luck in your endeavor! Ryan
