Alternatively to the method just offered, you could do an initial send 
of your parameters from gPXE, then your webserver could make a note of 
the association for the IP address to those details.  Your embedded 
script might then look something like:

#!gpxe
dhcp net0
set 210:string http://web-server/
chain 
${210:string}client?mac=${mac}&manu=${manufacturer:uristring}&model=${product:uristring}&serial=${serial:uristring}&asset=${smbios/3.8.0:uristring}&biosrev=${smbios/0.5.0:uristring}

and the webserver would cache these details for the client's IP and 
return another gPXE script like:

#!gpxe
chain http://web-server/pxelinux.0

which would then load PXELINUX.  Business from PXELINUX would then 
simply pull files with the http://web-server/ prefix, and the webserver 
would be responsible for returning appropriate things based on the 
client's IP address and the earlier associated details.  I don't know 
much about web-server scripts, but I know you have access to the 
client's IP address in most scripting systems.

Other than all of this trickery, you could simply have a vast PXELINUX 
config-file menu system, with all of your image options available.
