ML501 Platform Flash Configuration

Hello All,

I have a Xilinx ML501 board and I want to use the Xilinx XCF32P
platform flash to configure the XC5VLX50.

I can program the LX50 directly accross the JTAG chain and the design
runs correctly (flashing LED's).

Also the XCF32P does show up on the chain and Impact lets me program
it. Unfortunately, when I hit the program button my design does not
come up. The done LED goes true after a delay as if the part is
programming from some other source.

There is a 8 position dip switch on the board, SW15, that apparently
controls the configuration source but the documentation is not clear
about how to set that switch for platform flash. I have all zeros
selected now.

Can anyone just tell me how to set SW15 to configure from the platform
flash on the ML501?

Thank you,

Pete Dudley
