Using QEMM Optimize and the Windows 95 Startup Menu
Quarterdeck Technical Note #312 Filename: W95BOOT.TEC
by Jeff Sutyla CompuServe: W95BOOT.TEC
Last revised: 11/01/95 Category: QEMM
Subject: Using Windows 95's Startup Menu to Optimize a previous
version of DOS.
If you installed Windows 95 over an older version of DOS, you may
have a multiple configuration Startup Menu that displays when you
boot your system. The Startup Menu lets you pick the
configuration you want to use during bootup. For example, you
might have installed Windows 95 into a new directory rather than
installing over Windows 3.1. At times, you may want to boot into
Windows 3.1 instead of Windows 95.
If you use a Windows 95 Startup menu, you must make sure that
QEMM's Optimize boots into the same menu option each time
Optimize reboots your system. In this technote we tell you how
to set up a Windows 95 Startup Menu, select a default menu
option, and how to run Optimize using this default menu choice.
1. Boot your computer and watch for the message "Starting Windows
95". When you see this message, press the F8 key quickly. If
one of the choices is "Previous Version of DOS", note the
number of that choice and write it down. Choose "Normal" and
boot to Windows 95.
2. When Windows 95 has booted up, choose "Shutdown" from the
Start Menu, and then choose "Restart to DOS".
3. Make sure you are in the Windows 95 version of DOS by typing:
VER <enter>
If you see "Windows 95" on your screen, continue with Step 4.
If you do not see the "Windows 95" message, you likely have a
problem with your Windows 95 installation. Please consult
your Windows 95 documentation for assistance with this
problem, and do not continue with this technote.
4. In order to enable the Windows 95 Boot Menu feature, you must
make modifications to Windows 95's MSDOS.SYS configuration
file. Type the following:
CD \ <enter>
ATTRIB -S -H -R MSDOS.SYS <enter>
COPY MSDOS.SYS MSDOS.QDK
EDIT MSDOS.SYS <enter>
5. Add the following to the [Options] section of MSDOS.SYS:
BootMulti=1 ;Win95 Multi-Boot Configuration enabled
BootMenu=1 ;Win95 Multi-Boot Menu displayed by
;default
BootMenuDelay=5 ;Seconds to delay menu selection
BootMenuDefault=x ;Boots to item number x after the
;boot menu delay
Note: If you did not make a note of the menu number for "Previous
Version of DOS", do not add the BootMenuDefault= line.
Instead, press the keys <ALT-F> <X> <Y> to save the file,
then reboot the computer. When the Startup Menu displays,
make note of the menu number for "Previous Version of DOS",
then boot to the "Command Prompt Only" selection. Edit
MSDOS.SYS again, and add the BootMenuDefault= line. Press
the keys <ALT-F> <X> <Y> to save the file.
6. Type:
ATTRIB +S +H +R MSDOS.SYS <enter>
7. Re-boot your system. (If you end up in Windows 95, select
"Shut Down" from the Start menu, then select "Restart in MS
DOS mode".) Then type:
C:\QEMM\OPTIMIZE <enter>
to OPTIMIZE your previous version of DOS.
8. If you want to boot to WINDOWS 95 by default, follow these
steps. (If you do not, you are finished with this technote.)
Re-boot and choose NORMAL (choice 1) on the Startup Menu.
When WINDOWS 95 appears, choose "Shut Down" from the Startup
Menu, then choose "Restart to DOS".
Type the following:
CD\ <enter>
ATTRIB -S -H -R MSDOS.SYS <enter>
EDIT MSDOS.SYS <enter>
Place a semi-colon (;) before BootMenuDefault in the MSDOS.SYS
file.
Press the keys <ALT-F> <X> <Y> one after the other to return
to a DOS prompt, then type:
ATTRIB +S +H +R MSDOS.SYS <enter>
Now, when you boot your system the Startup Menu will be
displayed for 5 seconds and then WINDOWS 95 will automatically
start.
