KI will paint the screen blue starting from the top and flowing down to the bottom of the screen while it tests the RAM. If it fails, it will start painting the screen blue again and keep repeating.

Model: Killer Instinct
Symptom: Reboots when gameplay starts
Cust. was using a Compact Flash card as a replacement for a failed hard drive. Using a non-factory drive requires the replacement of the boot ROM with one that will work with any drive and the rebooting is caused by the wrong drive/ROM combination. Burned a replacement ROM, installed it, and successfully tested the game.
