You must run BASE, do as usual to slipstream your packs.
Then, before you create the ISO and/or burn to a disc, you need to replace the files in the OEM folder.
I do that, but DriverPacks Selector not runing on T39 - all driverpacks extrackting without choise
(ssory my bad english)
P.S. OK - I have solved this problem (has forgotten to change the file presetup.cmd in file I386 folder). But now after choice driver and unpackings gives the error: Cannot finde file c:\DSPdsblr.exe
What can I do ?
P.P.S. 
And this problem I have solved! Error in file presetup.cmd:
