I reduced the region size of our z/OS V1.4 test system's virtual machine and it IPLed OK @ 1 GB. No msg IEA303W. Given Skip's note about apar OA06207, it isn't clear what your real problem is (yet). Of course, YMMV with regard to region needs set in SYS1.PARMLIB and other places.
We had been using 2500 MB for our test system to allow it to test using memory above the bar.
