After I've slipstreamed SP2 into both xp home and pro, when I go to install it, it keeps prompting me to install drivers that aren't signed even though I set it to "DriverSigningPolicy=Ignore". Here's what it's doing:

where did you get SP2 from, because that shouldn't happen.

Did you "nlite" your windows?

It is a known error of nlite 0.98.7

Then try the new version of nlite....

Yup i did do it with nlite version .98.7 beta. Thanks for the help! I'll go try the newer version.

I slipstreamed sp2 in the classic way bat it keep sp1a files too (win51ip.sp1, sp1.cab, sp1.cat) Is this right?

Damnit, it still doesn't work. Except now during the text setup it says something about value 0 at [setupdisksfiles] (something like that) in sp2.cab. Gah this is getting annoying, SP1 used to be so easy to slipstream.
