The setup files for each platform (x86, MIPS, Alpha, or PowerPC) are located in their corresponding directory on the Windows NT Workstation and Windows NT Server Installation CDs. Copy each directory needed for the platforms running on your production LAN to the distribution sharepoint. For convenience, keep the names of the directories on the distribution sharepoint the same for each platform (for example, \i386 copied to \i386). Add any customization files to the distribution sharepoint, as discussed in Chapter 2, "Customizing Setup."
Be sure the directory on the distribution sharepoint is a shared directory.
