Help me building my legacy system

[Kreshna Aryaguna Nurzaman]

I plan to built a legacy system where I could shoehorn everything into it; a system where I can boot in DOS (to play DOS GLide games like Archimedean Dynasty), but can still play "newer" games (like WarCraft III) with reasonable performance.

Here's the plan for my system:
- Soyo SY845PE Motherboard (P4 mobo with ISA slots)
- Sound Blaster AWE 64 Gold
- Yamaha SW60XG WaveForce MIDI Card
- Voodoo5 5500 PCI Mac (BIOS flashed to PC)
- nVidia GeForce 6800 GT - AGP version
- A Pentium 4 CPU, preferrably non-HT
- 512 Mb of RAM
- MS DOS 6.22 / Windows 98 dual boot
- A KVM to switch between the two video cards

The Voodoo5 PCI is for playing DOS games (especially DOS GLide games) and Windows GLide games, while the GeForce 6800 GT is to play all Direct3D and OpenGL games. Thus, the V5 5500 is exclusively to play GLide games, whether they're DOS or Windows games.


The questions are:

(1) Which video card should I set as Primary in the motherboard BIOS? The Voodoo5 5500 (PCI) or the GeForce 6800 (AGP)?

(2) If I set the AGP card as Primary, can I still play DOS GLide games using the Voodoo5 5500 PCI?

(3) Likewise, if I set the PCI card as Primary, can I still play Direct3D and OpenGL games using the GeForce 6800 without too many hassles?

(4) What is the biggest challenge in building my legacy system? IRQ conflicts? etc?

(5) What is the best ForceWare driver to run the GeForce 6800 in Windows 98? And where to get it?

(6) What Pentium 4 Processor should I use? Since I'm using the SY845PE Mobo, of course my choice is limited to Northwood. Can I go with the highest CPU allowed (3.06 GHz) without conflicting with older devices like the Voodoo5 or the Sound Blaster AWE 64?

(7) Any further tips?
