What is the output from memShow when only vxWorks is loaded?  Does it
show the amount of RAM you think you have installed in the system?

You have defined these extra memory areas within sysPhysMemDesc and I
presume they maps onto several 32Mb VME RAM cards, but is this RAM being
added to the memory blocks being managed by the system anywhere?  For
each RAM area listed other than the default memory partition you need to
call memAddToPool, either somewhere in usrRoot(), elsewhere in sysLib.c
or in your startup script. Without these calls, vxWorks will not know
that it is in charge of these memory areas so will never allocate memory
from them.
