The scan is performed downwards from boot block image and searches first for POST, then
USER, and finally MCG images. In the case of multiple images of the same type, control is
passed to the first image encountered in the scan.
Safe Start, whether invoked by hitting ESC on the console within the first five seconds following
power-on reset or by setting the Safe Start jumper, interrupts the scan process. The user may
then display the available boot images and select the desired image. The feature is provided to
enable recovery in cases when the programmed Alternate Boot Image is no longer desired. The
following output is an example of an interactive Safe Start:
ABCDEInteractive Boot Mode Entered

Interactive boot commands:
'd':show directory of alternate boot images
'c':continue with normal startup
'q':quit without executing any alternate boot image
'r [address]':execute specified (or default) alternate image
'p [address]':execute specified (or default) POST image
'?':this help screen
