i see where you are comming from on this but if you are takling about a slim with a dvd drive board installed it adds delay with the tray status switches closed but it is still not enough to make a non picking up f and g partition as i tried all combinations of these inputs on a recent install and it did not help in my case.
The processor is still loading code from bios and the hdd is not having enough time to spin up which is the initial problem before the bios tries to find it.
holding the processor in reset while not resetting the hdd might be a possible option but i dont have any spare sata hdd's or sata to ide adaptors as i sold all to customers recently.
If slow spin up and sata adaptors are the problem then holding th xbox in reset while the drive and sata adaptor initilizes would be the best soultion.
If shorting pin one to ground on the motherboard ide connector causes the xbox to reset then the next thing to do would be to pull out pin 1 on a sata to ide adaptor and put a capicator between ground and pin one on the motherboard ide connector.
on power up of the xbox the capicator would charge holding the processor in reset while the hdd is powered and not being reset alowing it to spin up.
One problem may be that the smc is powered when the xbox is off and the reset pin may sink a small leakage current and charge the cap and you may need to put a relay running of the psu to break the connection of the capicator across the reset pin of the ide.
if the xbox does not reset when you short the reset line on the ide you might have to find the reset line from the smc which is the small microcontroller on the main board and do the same to the reset pin on there instead.
