Creating a Boothelper Disk Using a Windows PC
The boothelper disk, as described earlier in this chapter, provides assistance for Cisco PIX
Firewall models 510 and 520 running PIX software version 5.0(x) or version 4.x to be
upgraded to a newer version:
Step 1 Go to the Cisco website and download the rawrite.exe utility, which
you use to write the PIX Firewall binary image to a floppy disk (you
must have a Cisco.com account to do this).
Step 2 Download the PIX Firewall binary image (.bin file) that corresponds to
the software version to which you are upgrading.
Step 3 Download the corresponding boothelper binary file that matches the
version to which you are upgrading.
For example, if you are upgrading from PIX software version 5.0 to
6.1(1), you must download three files:
Password Recovery 93
• rawrite.exe
• pix611.bin
• bh61.bin (boothelper file)
Step 4 Run the rawrite.exe program by entering rawrite at the DOS prompt.
When prompted, enter the name of the boothelper file you want written
to the floppy disk, as shown in Example 4-4.
Reboot the PIX Firewall with the disk you created. The PIX Firewall comes up in boothelper
mode. Follow the procedure beginning with Step 3 of the earlier section “Upgrading the
Operating System Using Monitor Mode,” to continue with the upgrade process
