After reading the header, the loader transfers 0x IFF 32-bit words, beginning at
a specified destination address 0x 809C00. Code blocks require the same
byte and half-word ordering conventions. The loader can also load multiple
code blocks at different address destinations.
After loading all code blocks, the boot loader branches to the destination address
of the first block loaded and begins program execution. Consequently, the first
code lock loaded is a start-up routine to access the other loaded programs.
It is assumed that at least one block of code is loaded when the
loader is invoked. Initial loader invocation with a block size of
0x00000000 produces unpredictable results.
