NOTE
If the E5071C was turned off without shutdown process, Microsoft Scandisk runs while the
windows boot screens are displayed. If a serious problem is found in the scandisk, reinstall
the operating system. For details of the operating system installation, refer to Appendix B,
"System Recovery," on page 255. If the operating system still doesn't boot up properly
after reinstallation, replace the Hard Disk Drive.
NOTE
The operating system automatically checks the device drivers, which are necessary to use
the E5071C functions and are installed in the system before the E5071C is shipped from
Agilent factory. If the operating system doesn't detect them, a message box is displayed. In
this case, install the device driver.
Step 3. Revision and option information
The firmware revision and hardware option information along with copyright declaration is
displayed as shown in Figure 4-7. The E5071C firmware quickly starts up just before this
display appears. While the revision and option information is displayed, the applications of
various devices in the system are initialized.

If the display whited out, entirely blued or appeared with a dialog box, a mass storage
problem is suspected. Try to perform the mass storage recovery procedure.
