Boot Image Firmware Scan
Address

0xFF899999 to 0xFF8FFFFF
The scan is performed downwards beginning at the location of the first possible alternate
image and searches first for POST, then USER, and finally Alternate MOTLoad 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
