Table 54 Reset Status Description and Priorites

I/O Address	Reset	Reset	Description
457h	Signal	Priority1

D7	Main Power (+5V)	2	Main input power to cpuModule (+5V)
D6	CPU Core Power	3	CPU core powers supply
D5	Non-Standby Power	3	Power supplies that are not for standby
			power
D4	Memory Power	3	Power to onboard memory banks
D3	Standby Power	1	Standby power supplies
D2	Reserved	-	Reserved
D1	PCI Reset	4	PCI bus reset signal
D0	Utility Reset	-	Utiliy connector push button reset2

1.When a reset is asserted, all resets with a higher reset priority will also be asserted. For example, if the standby power reset is asserted, all other resets will also be asserted.

2.The BIOS allows the user to change the function of the utiliy connector’s push button reset. If the push button is not configured as a reset, this bit will always read a 0 (asserted) when the reset button has been pushed.
