You can embed multiple scripts by compiling like this:

# cd gpxe/src/
# make EMBEDDED_IMAGE=script1.gpxe,script2.gpxe,script3.gpxe bin/gpxe.lkrn

Where gpxe.lkrn is whatever build target you use.  Then you can run your 
scripts from the CLI like this:

gPXE> chain script1.gpxe

But perhaps you'd rather use aliases by using a script like this:

#!gpxe
set san1 sanboot iscsi:192.168.1.11
set san2 sanboot iscsi:192.168.1.11::::win7
echo Aliases have been set.

gPXE> ${san1}

or

gPXE> ${san2}

I hope this helps.  I've replied using the gPXE mailing-list, rather 
than the developers' list.  I hope you don't mind.
