During 32-bit client software installation, the setup program gives you the option of installing SQL Server Books Online. This option adds the SQL Server Books Online icon to the Microsoft SQL Server 6.0 program group. By choosing this icon, you can view SQL Server documentation online.
You can install SQL Server Books Online to run from disk (which uses more disk space but increases performance) or to run from CD (which reduces disk space used). You can also choose not to install SQL Server Books Online.
