default script for chainloading compatibility

[AT-HE]

hi

as we talked by mail ... is there any way to get included a default script to support chainloading without a dhcp server with user-class support?

imagine this pc booting

----
nvidia geforce 6200le
award bios 1.2 - press del to enter menu
cpu pentium 4 1200mhz
1204787 kb ok
booting from lan selected
dhcp: 192.168.1.3 assigned, boot image=undionly.kpxe
tftp: loading undionly.kpxe
tftp: loading default.ipxe
welcome to ipxe

... and customize default.ipxe to do anything we want? (boot from http depending on querystring, chain another image.. etc etc)

is anyway to download a precompiled undionly.kpxe with EMBED=myscript.ipxe , and myscript.kpxe with fixed

#!ipxe
chain default.ipxe

so anyone will be able to edit his own default.ipxe with custom options on tftp server root? (chainloadings, http images with custom urls, etc)

that is because is easier and fast to download a precompiled undionly.kpxe with this feature included instead of compiling by ourselves, besides many people doesnt know how to compile or cant compile in his machine (incompatible pc, doesnt have a compiler installed, etc)
