WPDOS - WP Under Windows: "Boot Windows 95 or 98 to the DOS prompt
If your computer comes with Windows 95 or 98, but you prefer to boot to a DOS prompt instead of to the Windows interface, you need to make only a slight change to one of your files. A similar change can be made to Windows Me, but only if you change other files as described on a third-party page mentioned below.
To make Windows 95 and 98 boot to the DOS prompt instead of to the Windows interface, change one line in the MSDOS.SYS file in the root directory. Use the DOS command attrib -h -s -r c:\msdos.sys to make the file editable; then open it in a text editor. Under the [options] heading, find the line that reads BootGUI=1 and change it to read BootGUI=0 (the final character is a zero). If no such line exists, create it. Save the file, and reboot. To start Windows, type win at the DOS prompt. The DOS that you access by this method is a true DOS, not an emulated DOS as in Windows NT, 2000, and XP; and this DOS (except in the first version of Windows 95) fully supports FAT32 drives.
Windows Me, as shipped, does not support the option to boot to DOS. A modification to Windows Me that restores this option may be found at one user's Windows Millennium Real-Mode DOS Patch page. This method modifies your Windows files, and should be used with extreme caution."
