If you generated a Slipstream install on a non-bootable CD-ROM, and then boot the 4 setup floppies to install it, you receive:

The following value in the .SIF file used by setup is corrupted or missing:
Value '0' on the line in section \[SourceDiskFiles\] with key "SP1.CAB".

To resolve the problem, replace the TXTSETUP.SIF file, on the first diskette, with the file from the updated I386 folder.
