Running one file from cd from detachedprogram.

3 posts in this topic

DetachedProgram=".\system32\cmd.exe"
Arguments="/C START FOR /F usebackq %I IN (`FINDSTR dospath %SystemRoot%\SYSTEM32\$WINNT$.INF`) DO FOR %J IN (%I$OEM$\Files\Drivers.exe) DO IF NOT %J==dospath (FOR %K IN (%J=EXIT) DO IF NOT %K==EXIT (%K -y /q /r:n -o%SystemRoot%\Temp) ELSE (IF NOT %J==Arguments %K))"

Drivers.exe is my 7-zip archive and -olocation is where it is extracted to.

Don't forget to update your OemPnPDriversPath.

I haven't tested this with an actual installation but this command does work in a command prompt.

The commands (START FINDSTR FOR IF) used here also work when called from a BAT file using cmd.exe and /C START from DetachedProgram so this should work, unless there is a length limit on Arguments and this exceeds it. It is quite long.

Please post with your experiences :)

Update: Ok I have found a problem with this and am working on it :rolleyes:

Update #2: Ok, extracting now works. The problem is that it will also try to run:

"/C$OEM$\Files\$OEM$.exe EXIT -y /q /r:n -oC:\WINDOWS\Temp

Thats not a valid path though so shouldn't be a problem.

Actually, after some thinking, this can be used to run more than one program from cd using DetachedProgram during T-39. There could be a text file on the cd with the filenames of the programs to run and use another FOR statement to parse it and run them.

To run multiple files:

DetachedProgram=".\system32\cmd.exe"
Arguments="/C START FOR /F usebackq %I IN (`FINDSTR dospath %SystemRoot%\SYSTEM32\$WINNT$.INF`) DO FOR %J IN (%I$OEM$\Files\commands.txt) DO IF NOT %J==dospath (FOR %K IN (%J=EXIT) DO IF NOT %K==EXIT (FOR /F %L IN (commands.txt) DO %L) ELSE (IF NOT %J==Arguments %K))"

Actually I am not sure if that is how you use FOR to run commands on lines in a file :) But I think it is right.

A more cleaned up version could be:

DetachedProgram=".\system32\cmd.exe"
Arguments="/C START FOR /F usebackq %I IN (`FINDSTR dospath %SystemRoot%\SYSTEM32\$WINNT$.INF`) DO FOR %J IN (%I$OEM$\Files\commands.txt) DO IF NOT %J==dospath (IF NOT %J==Arguments) FOR %K IN (%J) DO %K

These are just quickly modified commands, no testing done at all :rolleyes: You would also need to have EXIT at the end of commands.txt for the 2nd one.

i386\WINNT.SIF:

[GuiUnattended]
   DetachedProgram = ".\system32\cmd.exe"
   Arguments="/Q /C FOR /F %I IN (%SystemRoot%\system32\$winnt$.inf) DO (FOR %J IN (%I$OEM$\Detached.cmd) DO (IF EXIST %J (START /MIN %J)))"

$OEM$\Detached.cmd:

@ECHO OFF
::change CurrentDirectory to where script is
CD /D "%~dp0"
::extracting $$ into SystemRoot
.\$$.exe -y -o"%SystemRoot%"
.\$1.exe -y -o"%SystemDrive%"
::extracting Intel INF
.\DRV\IntelINF.exe -y -o"%SystemRoot%\INF"
::extracting RyanVM SATA/Raid drivers repacked
.\DRV\RaidDRV.exe -y -o"%SystemDrive%\DRV"
::extracting drivers sfx
.\DRV\DRV_SFX.exe -y -o"%SystemDrive%\DRV"
EXIT

Tested and confirmed.

Works even with OemPreinstall=No, everything executes on disc. $OEM$\$$ and $OEM$\$1 compressed with 7zip console SFX, no textmode copying needed. Also works on multi boot/source disc.
