Ok, so this is more of a techical problem rather then a simple fix. I picked up a mystery board and knew it was an IT board. Odds were it was either a golden tee or a BBH. Turned out to be a BBH hunter. The board was untested when when I plug it in, I keep hearing the speaker pop like if you were hitting the reset button on the board. Just to test, I swapped the bootrom and security chip to a GT board and the game boots up and runs but you cant do anything else but what the intro. Guess its a bit of a security thing? But I was wondering if anyone knows what could be up with the original BBH board. My voltages are all good, and so is the hard drive. The board resets before the hdd even starts to power up.
 
bump...no ones had this problem with a golden tee fore board before? Im starting to think the CPU on the board is shot since ive tried to change all the transistors and everything power related on the board.
 
Lots of issues with IT boards resetting during boot. Lots of reasons for them.

Power supply current issue (some boards draw more than others).
>10GB hard drive being used with an old boot rom that doesn't support it.
I have seen two boards with some sort of internal trace damage where it will reset but playing around with the board near the jamma connector/IDE area will get it working.

Power the board with nothing connected to it at all (no jamma, IDE etc.). Status 1 should flash every second consistently. If it doesn't press and hold the reset button in the middle of the PCB. Keep an eye on on the status 1 LED and play around with the board. push and twist gently in a few areas. Reset it again and see if you can find a "weak" spot. If you find it look for cold solder joints or board damage/cuts to traces.

Plug in the jamma harness, power cables. Press and hold the start button and power on the game while continuin to hold the power button. Keep watching the Status 1LED and see if the board goes into its self-test mode.

I can't seem to find it right now but I have read somewhere there was a problem like this. The guy powered the hdd from another power supply and got it to work some. He had several other errors though. Wrong type hdd, wrong version.

I would suggest watching the power supply voltages as it powers up. Could give you a clue if voltages are spiking.
 
I tried testing it a few different ways and none seemed to make a difference. The Status 2 LED thats by the modem (or where the modem usually is) is the only one that flashes. As soon as you turn it on, it sounds like you push the reset button once every second. My power level is spot on and ive even tried booting it with lower voltage. I also tried jumping out where the power contacts would be on the jamma connector (BBH has blank power connectors on the edge just like GT red boards but uses power from the HDD connector)
 
The LED that matters is the one in the middle of the board under the video card (Status 1). It should be flashing green every second.

Yeah I know, Im just completely lost on this thing. Like I said in my first post, the really weird thing is that if I swap the security chip, boot rom, and hdd to a GT board, it boots up and sits at the demo screen. Just no controls work or anything. I figured with ITs security it wouldnt even of gotten past the boot screen without an error.
