E8361A System Recovery Procedure
If the Operating System Does Not Boot From the Hard Disk Drive
If the network analyzer is unable to boot from the hard disk drive, then you must make a
DOS boot disk. To make this disk, you will need:
•a floppy disk
• a computer that is currently running DOS or Windows 95/98/ME/XP. Windows NT
or Windows 2000 cannot be used.
To create the DOS boot disk:
1. Right click on the
A: drive.
2. Select
Format.
3. Select
Make System Disk (or copy system files).
To boot from the DOS boot disk:
4. Insert the newly created system disk into the network analyzer floppy disk drive and
restart the operating system. The network analyzer should detect this disk and boot
from it. If not, proceed to “If the Operating System Does Not Boot From the Floppy Disk
Drive” on page D-6.
5. At the DOS prompt (
A:\>) type CD C: and press Enter. You are really changing to the D:
drive because a DOS operating system does not recognize the NTFS format and
assumes the first valid drive is C:.
6. Type
Autoexc.bat and press Enter.
7. Now that the analyzer system has booted, continue with the restoration procedure at
step 2 of “System Recovery Procedure” on page D-4.
