STM32F0-Discovery with HSE

I want to run my Discovery board with an external HSE soldered into X2 on the board. I ran the clock configuration tool and generated a new system_stm32f0xx.c which seems to be correct. It seems to still be using the 8 MHz PLL and I can't tell if it's not trying to use the HSE or is it failing when it starts up. I stuffed X2 (25 MHz), R23, R22, C14, C13 as shown on STM32Discovery schematic. I am using the Demo app that blinks the one LED and you can change the rate of blinking with the USER button. Ideally there is an explanation somewhere that says "If you want to use the HSE on the Discovery board do this ..." but I haven't found that. I'd appreciate any ideas of what to look at next.

Thanks.

Mike
