[gPXE] Setting delay time to boot

[Miller, Shao]

Good day Fatih,

In regards to introducing delays into gPXE's execution, please see the
"Customize" button found here[1].  While customizing, you may enable
"TIME_CMD" under the "Command Line Options" section.  This corresponds
to the same setting being #defined in gpxe/src/config/general.h and
compiling gPXE yourself.  This gives you the 'time' and 'sleep'
commands.  I think you are interested in the 'sleep' command, in
particular.
