Cisco Pix 520 OS

I am running a Cisco Pix 520 with cer 5.0.1 os. I would love to
upgrade the O.S. to the current version, but I do not have support at
Cisco. Since this is a used home system, I can not afford 2000.00 for
a year of support. Could someone give me access to the files I need
to tftp the Os to the current version, 6 x? something. I have plenty
of ram and flash ram, 128k and 16k I think,

My email is

PIX software licenses are not transferable, so you probably do not
have the right to run even 5.0(1) on the PIX.

You can buy a software upgrade instead of getting support.

Sorry, if I were to allow you to use the copy I have, I would
lose the right to use the software myself.

If you had a valid software license, you could possibly get the
TAC to upgrade you to something around 5.1(3) in order to fix
known security problems.
