My apologies for hijacking this older thread, but I am working on a GT Fore (2003 assumed security chip is G43) with the same issue (except monitor is blank and green instead of white) on two different green boards (a Rev 5 (boot v1.06) and Rev6 (boot v1.07)). Status 1 stays green, no IDE light unless you disconnect the molex connector and power it back on. The HDD (75AA) tests fine, 3 partitions (500MB, 1.5GB and 5.1GB unallocated). I can install a blank 40GB HDD and the IDE light will at least stay on during boot, but I don't get any output on the screen (I don't expect it to boot with the 40GB because of the wrong boot rom). When the guy bought it, it was working. Got it to his house and it would not boot. He has had about 3-4 people come out to work on it and they have replaced the power supply with a Suzo-Happ supply, replaced the motherboard. I have tested the voodoo3 video card in an older PC and it is working fine. I have wiped the HDD and reloaded the 2003 CHD, same result. It has a red dot matrix on top and I do get output to it, but not really readable as some of them are stuck on.
I've tried two different power supplies, and U15 pin 32 is showing 5.10V on both boards.
I know I need a new boot rom to use a larger HDD, but not sure that would fix all the issues.
lunatics, did you ever resolve your issue?
Thanks
