To do this, Norton Desktop modifies the [boot] section of the SYSTEM.INI file. To temporarily disable Norton Desktop, edit the SYSTEM.INI file in a text editor (such as Microsoft Windows Notepad), and change the line shell=ndw.exe so that it reads "shell=progman.exe" (without the quotation marks). Device Drivers Installed in the SYSTEM.INI File ----------------------------------------------- Norton Desktop for Windows installs three virtual device drivers (VFINTD, VDMADX, and VNSS) in the \WINDOWS\SYSTEM directory and places the following four lines in the [386enh] section of SYSTEM.INI: DEVICE=VFINTD.386 DEVICE=VDMADX.386 DEVICE=VNSS.386 DMABufferSize=21 The following is an explanation of the lines in the [386enh] section of SYSTEM.INI: Lines Description ----- ----------- DEVICE=VFINTD.386 Virtual Floppy Interrupt Device Driver DEVICE=VDMADX.386 Virtual direct memory access (DMA) Device Driver (replaces the default VFINTD, VDMADX, VNSS internal DMA device driver *vdmad) DEVICE=VNSS.386 Virtual Screen Saver Device Driver DMABufferSize=21 Sets amount of RAM reserved for buffered DMA (default=16) Removing or remarking out these lines causes Windows to exit to the command prompt when you try to start Windows in 386 enhanced mode.
