Installing and Recovering PIX Firewall Software

Preparing a Boothelper Diskette on a Windows System

Follow these steps to create the Boothelper diskette from a Windows system:

Step 1 Locate an IBM formatted diskette that does not contain useful files. Do not use the PIX Firewall boot

diskette that came with your original PIX

Firewall purchase—you will need this diskette for system

recovery should you need to downgrade versions.

Step 2 Enter rawrite at the MS-DOS command prompt and you are prompted for the name of the .bin binary

file, the output device (a: or b: for a 3.5-inch diskette), and to insert a formatted diskette. A sample

rawrite session follows.

C:\pix> rawrite

RaWrite 1.2 - Write disk file to raw floppy diskette

Enter source file name: bh512.bin

Enter destination drive: a:

Please insert a formatted diskette into drive A: and press -ENTER- :

Number of sectors per track for this disk is 18

Writing image to drive A:. Press ^C to abort.

Track: 78 Head: 1 Sector: 16

Done.

C:\pix>

Ensure that the binary filename is in the “8.3” character format (8 characters before the dot; 3 characters

after the dot).

Step 3 When you are done, eject the diskette, insert it in the PIX Firewall diskette drive, and power cycle the

unit. Alternately, if available, use your unit’s Reset switch, or enter the reload command from the

PIX

Firewall console. The PIX Firewall then boots from the new diskette.

Downloading an Image with Boothelper

Follow these steps to use the Boothelper diskette to download an image from a TFTP server:

Step 1 Download a PIX Firewall image from Cisco.com and store it on the host running the TFTP server.

Step 2 Start the TFTP server on the remote host and point the TFTP server to the directory containing the

PIX

Firewall image. On the Cisco TFTP Server, access the View>Options menu and enter the name of

the directory containing the image in the TFTP server root directory box.

Step 3 Connect a console to the PIX Firewall and ensure that it is ready.

Step 4 Put the Boothelper diskette you prepared in the PIX Firewall and reboot it. When the PIX Firewall starts,

the

pixboothelper> prompt appears.
