Hello jimmyboy,
I have my 1200 in a Power Tower, so I'm not sure if the keyboard adaptor is the same, but here is one way to get the ppc startup on my machine. First boot with no startup, then reboot with ctrl-A-A and hold down the esc key, I get the menu.
I have my VooDoo 3 in the second slot, then my ethernet, then my SB, no spaces. The usb ports from the Subway are blocking the first slot.
No loose wires in my case.
My Mediator settings:
8mb closed,
config open,
wait open,
wake-up open.
I have an SX so it might be different.
I hope this helps.
Xand
