XILINX Foundation F1.5 Build 3.1.1.35 with XCS10PC84 and Dig

I am attempting to use this XILINX software with this board and chip.
In order to test it, I create a simple design that incorporates an
AND2 gate, two input buffers, and one output buffer all of which (the
input and output buffers) are connected to IPADs. The IPADs are
assigned pin numbers on the Schematic with the parameters LOC=Pxx,
where xx is 27, 28, and 69. These correspond to SW1, SW2, and LD1.

The design implements correctly, and the bit file is generated
successfully. When I transfer the design to the board, NOTHING
HAPPENS!

This is a very frustrating problem, and I cannot determine the
solution. If I can't get this simple design to work, then the boards
are practically worthless.

I installed the two recommended updates for the F1.5 software,
ftp://ftp.xilinx.com/pub/swhelp/M1.5_updates/15_service_pack1_nt.zip
and ftp://ftp.xilinx.com/pub/swhelp/M1.5_updates/15_sp1_ftp2_nt.zip.
I don't know what else I am supposed to upgrade the software with to
perhaps fix this problem. I have already tried other miscellaneous
patches posted on the site, but none allows this simple design to
work.

Has anyone else encountered this problem with XILINX Foundation F1.5,
and the Digilab XLA with the XCS10PC84 chip?

Thank you.

Does the Done pin go high?

Try something even simpler: just connect an output from the
OSC4 block to an output.

Fix for Digilab XLA and Xilinx Foundation F1.5 Software
-------------------------------------------------------

In order to get Xilinx Foundation F1.5 to work properly, it is first
necessary to install these two updates:

ftp://ftp.xilinx.com/pub/swhelp/M1.5_updates/15_service_pack1_nt.zip
ftp://ftp.xilinx.com/pub/swhelp/M1.5_updates/15_sp1_ftp2_nt.zip


If your DigiLab XLA board fails to run your designs, even after you
have transferred them via the parallel cable successfully, then this
board modification should remedy the problem.

1. Find chip U4 on the board (labeled "Japan 00 33 H 74HC125AP"),
which is located close to the parallel port.

2. Pull out the chip.

3. Find pin #6 on the chip. Orient yourself by locating pin #1, which
is on the upper-left side of the chip.

Figure 1 - Pin #6 on the U4 Chip.

4. Bend this pin (pin #6) out by extending it parallel to the base of
the chip. It should not be able to reach the contacts when
reinserted into the board.

5. Reinsert the chip into the board.

6. Test the board. It should function properly now.
