First reinstall your old module to figure out if the Bootrom is ok. If the new
Bootrom works with your old module (it must work) try to install the new modules
again one by one in order to see if one of them is broken. Use the lower slot
for single processor use! 

What CPU was installed before? I had to change some jumpers since the old mbus
module was a 36 MHz one which required a different SBus clock. I had to change
it to the standard 40 MHz setting.
