Sysstup.inf Error

[MagicLB]

Hello,

I Have some questions about syssetup.inf.

I have expand the syssetup.in_ to modify it.

i goto [DeviceInfsToInstall] an change the following

[DeviceInfsToInstall]

;pnpscsi.inf

;scsi.inf

I save the file and use the makecab command to compress the file to syssetup.in_.

I burn my Windows XP SP2 files to a cd and i would like to install Windows XP SP2.

Windows copy the files and make a restart, after the Gui is started Setup will hand @ t-39 with the following error:

The Signature of the applicant is invalid

In German :Die Signatur des Antragstellers ist ungültig.

What have i did wrong ???

Thanks

Lars
