531) The BSP is tested with the 60x bus mode instead of the MPX bus mode.
54   ( No jumper or a jumper across pins 1-2 on J19 selects the 60x bus mode)
55
562) On the mvme5500 board, Ethernet 1 is the Gigabit Ethernet port and is
57   front panel only. Ethernet 2 is 10/100 BaseT Ethernet. For front-panel
58   Ethernet2, install jumpers across pins 1-2 on all J6, J7, J100 and
59   J101 headers.
60
613) Enable SROM initialization at startup. (No jumper or a jumper across
62   pins 1-2 on J17)
63
64In fact, (if I did not miss anything) the mvme5500 board should function
65properly if one keeps all the jumpers at factory configuration.
66One can leave out the jumper on J30 to disable EEPROM programming.

71BSP BAT usage
72----------------------
73DBAT0 and IBAT0
740x00000000
750x0fffffff  1st 256M, for MEMORY access (caching enabled)
76
77DBAT1 and IBAT1
780x00000000
790x0fffffff  2nd 256M, for MEMORY access (caching enabled)
80
81UPDATE: (2004/5).
82The BSP now uses page tables for mapping the entire 512MB
83of RAM. DBAT0 and DBAT1 is hence free for use by the
84application. A simple 1:1 (virt<->phys) mapping is employed.
85The BSP write-protects the text and read-only data
86areas of the application.  Special acknowledgement to Till
87Straumann <strauman@slac.stanford.edu> for providing inputs in
88porting the memory protection software he wrote (BSP_pgtbl_xxx())
89to MVME5500.

92The default VME configuration uses DBAT0 to map
93more PCI memory space for use by the universe VME
