Photo Play (c) 199? Funworld

Preliminary driver by Angelo Salese

TODO:
- BIOS CMOS doesn't save at all (needed for setting up the Hard Disk);
- DISK BOOT FAILURE after eeprom checking (many unknown IDE cs1 reads/writes);
- partition boot sector is missing from the CHD dump, protection?
- Detects CPU type as "-S 16 MHz"? Sometimes it detects it as 486SX, unknown repro (after fiddling with CMOS settings anyway)
- VGA BIOS reports being a Cirrus Logic GD5436 / 5446, it is unknown what exactly this game uses.
- PCI hookups (no idea about what this uses), and improve/device-ify SiS85C49x;
- ISA bus cards are completely guessworked;
- EEPROM timings are hacked (writes mostly fail otherwise);
- Eventually needs AudioDrive ES688 / ES1688 / ES1788 & ES1868 devices and serial ports "for linking" before actually booting;
