HOWEVER: Since it (on the surface) seems like such a Blatant and Obvious mistake here you go...

you wrote
SET DRV=%SystemDrive%\Drivers
.\7za.exe x -y -aoa -o"%SystemDrive%\Drivers" ".\Drivers.7z"
)

the Syntax is
7z [source] [destination]
not
7z [destination] [source]

so you should have written
IF EXIST Drivers.7z (
SET DRV=%SystemDrive%\Drivers
.\7z.exe -y -aoa ".\Drivers.7z" -o"%SystemDrive%\Drivers"
)

Let us know if you get it to work

IDK if we can help since this is a little off topic,
but your welcome to ask...
and i know we would love to hear that you got it to work

PS that artical is over 4 years old... and much has happened since then...

take a look in our FAQ about SAD (To be renamed SoFI)
I belive SAD created with M2 will be a better solution for you.
SAD still has a few glitches we are ironing out but you can check it out by clicking on the link on our homepage

it is the second news item on the page

The thing is, i got the compressed drivers in 1 file called Drivers.7z, inside U:\$WIN_NT$.~LS\$OEM$\Drivers (drive letter for my usb-stick is always U:) The frist time i try the install win xp and the drivers and not work, then i try, try, try, and try, and i looking for the problem, i read the file Drivers.cmd and i see the code is for a CDSOURCE, not for and removible usb and less for a usb-stick with the letter drive is always U:

I think the problem is that, just the code the drivers.cmd and the search for a cdsource and the dir tree in the usb-stick is no match a cd instalation method.

I let you my dir tree from usb-stick

U:
---\$WIN_NT$.~BT
----------------------\system32
---\$WIN_NT$.~LS
----------------------\$OEM$
-------------------------------\Drivers\Drivers.7z
----------------------\I386

This is the code for drivers.cmd
