Xp repair using slipstream

I want to repair an XP system drive, And i want to change my winnt.sif file on my xp slipstream CD, Because it does not bring me the repair option in the text based mode part of the windows setup.

This is the relevant part, And i will appericiate suggestions :

[Data]
AutoPartition=0
MsDosInitiated="0"
UnattendedInstall="Yes"
AutomaticUpdates=yes

[Unattended]
OemPreinstall=No
UnattendSwitch="yes"
UnattendMode=FullUnattended
OemSkipEula=Yes
TargetPath=\WINDOWS
WaitForReboot="No"
FileSystem=*

Thank you (Well....that's not a part of the winnt.sif file :O))
