The <command>load</command> command is used to download
data into the target system. Data can be loaded via a network connection,
using either the <acronym>TFTP</acronym> or <acronym>HTTP</acronym> protocols, or the console serial connection using the
X/Y modem protocol. Files may also be loaded directly from local filesystems
on disk. Files to be downloaded may either be executable images in 
ELF executable program format,
Motorola S-record (SREC)
format or raw data.
