5This file documents the on board monitor (PPCBUG) configuration used
6to be able to boot the archives located in powerpc-rtems/c/mcp750/bin.

9NOTE (by Till Straumann <strauman@slac.stanford.edu>, 2003):
10Apparently, PPCBug fails to shut down the network interface after
11loading an image. This means that the ethernet chip is still able
12to write into its descriptors and network buffer memory which
13can result in the loaded system to be corrupted if that system
14relocates itself!. The proper place to shut down the interface
15would be PPCBug itself or a 'PPCBug startup script' - unfortunately,
16PPCBug doesn't offer such a feature. Therefore, the bootloader
17is by default compiled with the
18#ifdef USE_PPCBUG
19compile-time option ENABLED. It will then use a PPCBug system
20call to shut down the ethernet chip during an early stage of
21the boot process.
22NOTE: THIS (i.e. the system call) WILL FAIL IF YOU USE SOFTWARE
23OTHER THAN PPCBUG TO BOOT THE BSP. In such a case, you must
24recompile with #undef USE_PPCBUG and make sure the ethernet
25interface is quiet by other means.
