Appendix C: Troubleshooting106
After the diskette is formatted and the operating system files are transferred, you will be
able to boot the computer from the diskette. If you restart your computer with the diskette
in the diskette drive, your computer boots using a minimal amount of conventional
memory. After you boot from the diskette, you can run Drive Image from either the
diskette or your hard drive.
If you want to create and restore images across a network, you will need to create a
network boot diskette.
Creating a CONFIG.SYS File on the Boot Diskette
If making an ordinary boot diskette doesn't free enough conventional memory, you can
create a customized boot diskette that will free even more conventional memory. (With the
customized diskette, you will free more conventional memory by loading some of the
DOS operating system into high memory.) To customize the diskette, you must create a
CONFIG.SYS file in the root directory (A:\). To create a CONFIG.SYS in the root
directory, perform the following:
1
At the DOS prompt, type drive: (where
drive
is the drive letter of the diskette
drive), then press <Enter>.
Verify that you have changed to the diskette drive (you see the drive:\> prompt).
2
Type EDIT CONFIG.SYS and press <Enter>.
This starts the DOS editor. (You will see a blank screen if no CONFIG.SYS currently
exists.)
3
In the editor, type the following:
DEVICE=C:\DOS\HIMEM.SYS
DEVICE=EMM386.EXE
DOS=HIGH,UMB
IMPORTANT!
All lines must be entered in the order shown. Windows users:
substitute DEVICE=C:\WINDOWS\HIMEM.SYS.
4
Click File
➤
Save to save the file.
5
Click File
➤
Exit to exit the editor.
You can now reboot your computer from the customized boot diskette. When DOS loads,
much of it is loaded into high memory, saving a maximum amount of conventional
memory.
