Bâshrat the Sneaky Posted June 18, 2004 Share Posted June 18, 2004 Set in your winnt.sif:[Unattended]DriverSigningPolicy=Ignoreor to keep it signed: simply don't remove the .cat files. Link to comment Share on other sites More sharing options...
weihuisheng Posted June 20, 2004 Author Share Posted June 20, 2004 thanksanother problem I want to know is that when I modify the inf file of the driver,is the cat file still available?? Link to comment Share on other sites More sharing options...
Bâshrat the Sneaky Posted June 20, 2004 Share Posted June 20, 2004 thanksanother problem I want to know is that when I modify the inf file of the driver,is the cat file still available??Yes. Somewhere in the beginning of an .inf driver file there's a .cat file mentioned. If you don't delete it, it will remain a signed driver Link to comment Share on other sites More sharing options...
TechTalker Posted June 21, 2004 Share Posted June 21, 2004 Hmm, don't think so.Why are people signing drivers?One good reason is that they want to guarantee the driver is unchanged! If you change the driver e.g. by editing the INF the driver is changed and the CAT doesn't fit to the driver (the CAT contains a hash). Or you may also say the driver is unsigned.

If you change the driver e.g. by editing the INF the driver is changed and the CAT doesn't fit to the driver (the CAT contains a hash). Or you may also say the driver is unsigned.Then let's take a quick look at one. Here's the inf of the Audigy ZS' driver:[Version]Signature="$CHICAGO$"Class=MEDIAClassGUID={4d36e96c-e325-11ce-bfc1-08002be10318}provider=%CREAF%LayoutFile=layout.inf, layout1.inf, layout2.infDriverVer=10/21/2003, 5.12.05.0441CatalogFile=wdma_emu.cat<========================== Link to comment Share on other sites More sharing options...
TechTalker Posted June 21, 2004 Share Posted June 21, 2004 OK, the reference to the CAT file is still in the INF but the signature is no more valid for any changed files. The CAT file contains a tag and hash code for every component of the driver. If one of them is changed the signature is broken.I tried to find some info about this mechanism. The following PowerPoint presentation is the best I found: http://download.microsoft.com/download/a/f...740/driver2.ppt Link to comment Share on other sites More sharing options...
Bâshrat the Sneaky Posted June 22, 2004 Share Posted June 22, 2004 oh... Didn't know of that. I'll read it later, now I've got to go to school to make my exams... Link to comment Share on other sites More sharing options...
weihuisheng Posted June 22, 2004 Author Share Posted June 22, 2004 Yes,thanksI think it will be changed and the catelog file will be unsigned! Link to comment Share on other sites More sharing options...
weihuisheng Posted June 22, 2004 Author Share Posted June 22, 2004 thanks ,Bâshrat the Sneaky[unattended]DriverSigningPolicy=IgnoreWill it work??I don't have a chance to try it myself.but I modify my winnt.sif as you said.waiting for the next installation.......

weihuisheng Posted June 22, 2004 Author Share Posted June 22, 2004 Another thing I want to know is that the changes to winnt.sif will be automatically applied to the xp installation?When I modify the winnt.sif and put my personal settings into it,could I get it automatically applied in the xp installation?Could I get the xp unattended installation by modifying it instead of using the windows unattended installation?

Bâshrat the Sneaky Posted June 22, 2004 Share Posted June 22, 2004 Of course it's applied. What else would be the advantage? Link to comment Share on other sites More sharing options...
weihuisheng Posted June 25, 2004 Author Share Posted June 25, 2004 You mean I could set my IP, my networkand so on in it??It will be applied?? Link to comment Share on other sites More sharing options...
Bâshrat the Sneaky Posted June 25, 2004 Share Posted June 25, 2004 Yes, if you do it correctly. A great help may be the deploy.chm, which you can find in the Deploy tools. Link to comment Share on other sites More sharing options...
