MBR read failed, means you have a bad or invalid OS card for your bios. Your monitor is also not the 20" variety since those are widescreen. You have the older 19" 4:3 monitors typical of the earlier M9000's. It looks like you would need:
1. A known working 19" M9000 touchscreen monitor.
2. 807 bios, 317 OS and a 312 card.
3. A known working compatible game with your hardware platform.
If the game does not work after getting all that, then, you would likely need a new MPU. The difference in price between the older 300/400 mhz mpu's and the 1Ghz mpus can be as much as $200 depending on current availability and your source. Make sure you buy one that has been tested and known to be working correctly, whichever type you decide to get. Also a good idea to put new batteries on them before you even try to get them going.
