Your copy does not have txtsetup.sif? Txtsetup.sif is an essential file for setting up windows. It's also an essential file that hfslip modifies to add new files for install. If you don't have txtsetup.sif, then hfslip won't work for you either.
Found it with help from another forum. Its in the AMD64 folder. so it should work now right? Where would I put the drivers for SATA so I can slipstream them into the mix for a new xp pro 64 sp2 w/ sata drivers ? Are there more than one set of drivers I need to worry about or just the ones I got from my mobo manufactures web site?
