i have a cisco pix515e firewall i bought from ebay. for some reason everytime i make changes using the ASDM panel, it will always do this rebooting and it gives me a message the says

Begin to dump crashinfo to flash....
End of console dump.
Do 'show crashinfo' after reboot to retrieve other crash information

Embedded BIOS Version 4.3.207 01/02/02 16:12:22.73

what can i do. why am i seeing this problem.? at first i thought it was a problem with a quad nic that i had installed, but i removed it and it still reboots and it crashes..

dont know what to do
