The test against bit 2 of IXP1200_GPIO_DATA is a check on jumper J27. The README.jumpers.txt says to set J27 to 2-3. Is J27 set correctly?
Yes, J27 is set correctly. In fact, there isn't any need to change J27 since the factory's setting is similar to Vera's setting. But I used the ixp board without using the serial cable connected because I was concerned whether Pentium will get booted up or not. In that case, I guess, it is a must to connect up the serial port of the ixp board.
At this point I cannot think of another (simple) explanation as to why you would see "16" on the leds without GPIO bit 2 (0x4) being set. There is no requirement that the serial port of the IXP1200 board be connected. However, as you can see, it's more useful to connect it to a different machine so that you can see the output messages even if the host Pentium doesn't boot for some reason.
If J27 is set to 1-2, the board enters minimon *before* initializing the PCI bus. The BIOS will hang because the IXP1200 is not responding to the BIOS query. You can verify this by checking the serial port output from the ixp1200 board.
Can I confirm that the mini-monitor in $VERAROOT/Runtime/ixp1200/sa/src/Lib/ will work with both Window's Hyperterminal as well as linux minimon?
Minimon uses no special control codes and will work with any RS-232 terminal or terminal emulator set to 9600 baud, 8 data bits, 1 stop bit, no parity. Scott
