I have a 12 MHz Suntac 286 Motherboard. My power supply died yesterday and when trying 2 different power supplies the Suntac card does not always boot. The whole screen is white. I have to cycle power off-on until the screen goes blank and the machine boots. (Reset button doesn't work) I have tried different things with the Power-OK signal but nothing seems to fix the problem. My current theory is that the Suntac MB is very sensitive to Power sequence timing, and that some kind of lock-up occurs often with certain power supplies. Do you have any suggestions ?? /Hans-Ove Frimodig hoven@cd.chalmers.se
