Question about PCI lock

Will a motherboard's PCI lock feature also lock the following ?

USB ports
S-ATA
Firewire
Other connections off the motherboard ?

Or does it just lock the actual PCI slots?

Thanks !

It will lock anything that uses the PCI bus clock, that means most onboard things will be locked. The clocks for USB should always be locked, as I believe they take off from the fixed 24 and 48 MHz PLL outputs.
