Ah, in my experience, (PM7500) 'tis the deepest of the black arts.
Too little, Too much 4 fingers, doesn't go.
This is my procedure:
1. Firmly hold down all 4 keys, _without_touching_ any other key. The
"hold down all 4 keys" is a PITA, but the _without_touching_ bit
is a subtile wrecker. I think the keyboard has radar.
2. While firmly holding down the 4 keyes, key the power on, and
listen for the chime.
3. At the instant you hear the chime, _immediately_ release all four
keys. If the chimes start to die off, and your fingers are still
on the keyboard, you're dead.
That's how we boot our 7500's. Hope that helps.
