A.2 PCI Expansion Card (Thimble Peak 2)
(Included)
The PCI Expansion Card (Thimble Peak 2) is provided to offer 3 PCI slots and one
goldfinger PCI slot on the evaluation board. The expansion card also contains a floppy
disk drive connector, parallel port connector, and a serial port connector. To connect
the card, slide the horizontal PCI connector on Thimble Peak 2 onto the gold-fingers
on the development board. To connect the LPC bus enabling the floppy disk drive
connector, parallel port connector, and a serial port connector, connect the ribbon
cable as depicted in Figure 11
. CLKRUN protocol is supported on Thimble Peak 2 board
for only those PCI cards which support CLKRUN#, else CLKRUN# should be disabled in
BIOS.
Upon boot up, the system BIOS automatically detects that the PCI expansion card is
present and connected to the system. The system BIOS then performs all needed
initialization to fully configure the expansion card. For additional information see the
LPC docking connector on the evaluation board schematics.
