Welcome to OpenBIOS v1.0 built on Mar 31 2009 15:35
checking for memory...
0: base = 0x00000000, size = 134217728
1: empty region
total physical memory = 128 MB
suggested page table size = 1048576
need new page table, size = 1048576!
new table at: 0x07d00000
found 4 translations
found page table!
no mapping for the exception handlers!
