Hi . make sure you follow this procedure step by step ..?
The following steps describe how to upgrade the PIX Firewall using monitor mode:
Step 1 Download the binary software image file pixnnx.bin, where nn is the
version number and x is the release number (which you can find at
Cisco.com in the document ?Cisco PIX Firewall Upgrading Feature
Licenses and System Software?). Place the image file in the root of your
TFTP server.
Step 2 Reload the PIX Firewall, and press the Esc key (or enter a BREAK
character) to enter monitor mode. For PIX devices running Version 5.0
and earlier, a boothelper disk is required. (See the section ?Creating a
Boothelper Disk Using a Windows PC? later in this chapter.)
Step 3 Use the interface command to specify out of which PIX Firewall
interface the TFTP server is connected. The default is interface 1
(inside). The Cisco PIX Firewall cannot initialize a Gigabit Ethernet
interface from monitor or boothelper mode. Use a Fast Ethernet or
Token Ring interface instead.
Step 4 Use the address command followed by an IP address to specify the PIX
Firewall interface IP address.
Step 5 Use the server command followed by an IP address to specify the TFTP
server?s IP address.
Step 6 Use the file command followed by the filename of the image on the
TFTP server to specify the filename of the Cisco PIX Firewall image.
Step 7 Use the ping command followed by the IP address of the TFTP server
to verify connectivity. (This is an optional but recommended command
to test connectivity.)
NOTE Under no circumstances must you ever download a Cisco PIX Firewall image
earlier than Version 4.4 with TFTP. Doing so corrupts the Cisco PIX Firewall Flash
memory unit and requires special recovery methods that must be obtained from the Cisco
Technical Assistance Center (TAC).

Step 8 If needed, enter the gateway command to specify the IP address of a
router gateway through which the server is accessible. (This is also an
optional command.)
Step 9 Enter tftp to start downloading the image from the TFTP server.
Step 10 After the image downloads, you are prompted to install the new image.
Enter y to install the image to Flash.
Step 11 When prompted to enter a new activation key, enter y if you want to
enter a new activation key or n to keep your existing activation key.
I hope it helps .. please rate it if i does !!!
