Attention: Some PCs with multiple PCI slots that support Wake on LAN and
3.3-volt auxiliary power may not have an adequate 3.3-volt power supply to power
more than just a few of the slots with auxiliary 3.3 volts. Check with your PC
supplier to determine the number of PCI slots that can be concurrently populated,
and still meet the current limit of 375 mA per slot (for auxiliary 3.3 volts). This limit
is specified in the PCI Bus Power Management Interface Specification Revision 1.1.
