Midway Quicksilver skeleton driver
TODO:
- Currently fails to recognize a PCI card with ID 0x71108086:
Chip Number: 82371AB/EB/MB
Chip Description: PIIX4/4E/4M ISA Bridge
Notes: IDE
... that is obviously hooked but current PCI emulation doesn't return
ID vendor -.-"
- Tries to read 0x8 / 0xc registers of the PIIX4 PCI card, unknown
purpose;
Main CPU : Intel Celeron 333/366MHz
Motherboard : Intel SE440BX-2
