The console stores the boot device name in these 15 bytes. The name is stored
as up to 15 alphanumeric ASCII characters, padded to the right with 0s as
necessary. These data are first copied to a scratch RAM buffer; they are passed
to the APB program as a pointer to an ASCII descriptor list in register R0 when
boot defaults are required. This field is zeroed at detection of an NVR failure at
power on. It may be inspected and modified using the console SHOW/SET BOOT
console commands.
