we use the DriverPacks finisher to monitor those registry entries while it runs...
did you not read what i wrote or do you just think i am stupid?
or was the statement "(they aren't registry entries, they are windows setup parameters /  switches)" somehow unclear?

please don't 'Guess' when i have given you the answer already.
(I did not have to guess i already knew the answer)
um this is your first day and you think you can suddenly find some secret that this team of people who have spent years doing this missed?

sorry... i get a liitle terse when my cage is rattled

why dont you experiment with it a little and after you are familiar with the basics we will do a Q&A again if need be.
I think you will find almost anything you want to know is already covered here somewhere. ( search feature )

Welcome to DriverPacks

"if you remove the entries from winnt.sif then the install may hang asking about unsigned drivers..."

-------is this "hang" just a request(tip) for the drivers which does not through WHQL when you install them? the system will ask you to continue or not.

and I found a nlite.inf file in the I386 folder after integrated drivers with nlite.
like this:
----------------------------------------------------------------------------------------------------------------
[T]
HKLM,"SOFTWARE\Microsoft\Driver Signing","Policy",0x00000001,0
HKCU,"SOFTWARE\Policies\Microsoft\Windows NT\Driver Signing","BehaviorOnFailedVerify",0x00010001,0"
----------------------------------------------------------------------------------------------------------------

Do you konw what's this reg?

I guess it's the reg method for this
[Unattended]
    DriverSigningPolicy=Ignore
    NonDriverSigningPolicy=Ignore

Just guess

Method one is considered obsolete. it has a path limitation of 4096 characters which we exceeded long ago.
it also cab compresses the files which takes up a larger amount of disk space (7zip=300meg - cab=500meg)
it takes a few hours to extract and them cab them the first time (with QSC=ON you will not have to cab them a second time).
This also causes windows setup to copy the drivers during textmode and is quite a bit slower than copying them during winpe.
   but... this would put all your files in the $OEM$ folder.

with method two the drivers are put in OEM because we don't want them copied during textmode, so they are not in $OEM$.

I would respectfully suggest you not fool with it and just accept the new OEM folder we create... its the best solution and has been in use for years and tested by thousands of users - (if it ain't broke don't fix it).

if you remove the entries from winnt.sif then the install may hang asking about unsigned drivers...
if you are not doing an unattended install this is probably not a big deal since ther are only a handfull of drivers that we know of that need these entries - and even that handful will only gripe if the hardware is actualy present in the system.
(since it's an 'attended' install you are expecting it to stop for user input anyway what is one more dialog box when your doing a repair?...)
these entries can not be created by any other method. (they aren't registry entries, they are windows setup parameters /  switches)

Do I need to change some other settings after moved?

----------------------------------------------------------------------------------------------------
and the winnt.sif file

If I need to enable the repair function, have to remove the [Unattended] option,

[Unattended]
    DriverSigningPolicy=Ignore
    NonDriverSigningPolicy=Ignore

this two options will be gone, so is there any bad effect if remove these two options?

if do need these two, how to convert the two into reg or some other method and add it into system when installed.

Thanks!!!
