How can i make a multiboot dvd with only one directory for drivers?
I've used flyakite guide and i want a dvd structure like this:

-BOOT
-PRO
-HOM
-SETUP\PRO
-SETUP\HOME
-DRIVERS

I've tried edit txtsetup.sif and change the setup source in \SETUP and add \PRO to all drivers source but when pc reboot,the installation continuosly installation path in d:\setup

there's a setting in winnt.sif called "OemPnPDriversPath" i think this could be what you're looking for

Ok, I've tried using setupORG.exe and presetup.cmd founded in driverspack forum and all works well. But now i want to try using DetachedProgram switch in winnt.sif

you want only one folder to save space or just for better looking?
put the same DRIVERS folder in every windows folder and optimize your ISO so you'll store the folder only one time, saving space and time.
