6-4 Installing Windows NT Server 4.0 Enterprise Edition
Enable 4 GB Support
After installing NT Server 4.0 and installing Service Pack 3, you must update
the C:\boot.ini file to enable 4GB support.
To update the C:\boot.ini file, follow these steps:
1. The boot.ini file is a hidden file. You must “unhide” the file before you
can select it for editing. Through Explorer, select View, select Options,
and then select “Show All Files.”
2. You also must change the properties associated with the boot.ini file to
something other than “read-only” so that you can edit the file. Through
Explorer, select boot.ini, select File, and then select Properties. Select
something other than “read-only.”
3. Edit the file and add the /MAXMEM:3GB option to the NT start-up line.
Note: Refer to the “Enabling 4GB Support in Your Application” section of
the Windows NT Enterprise Edition Installation Guide for additional
information.
