I have a sparc IPC. It has 3 memory banks (0,1,2) of 4 simms each. I have 2 banks of 1MB simms and 1 of 4MB simms. Right now I can't boot from the 1.4.2 syboot.fs I think because of the memory mapping problem. Does anyone know if there is a particular combination of how I install this memory which can work around it? Thanks -Dan
