well i guess you need a password recovery first.

once you are able to login to your asa from privilage mode execute the following commands:

erase mem
write mem
reload

i think once you login the command may be 'erase flash' then 'reload'

i'm not quite agreed with nqravatt. if this command works it would wipe out everything from the flash including your asa image and causing pritty rough exercise restoring the image by using xmodem. anyway i've just googled it and it appears that the old pix firewalls had the "configure factory-default" command. more likely works for asa as well.  erase mem makes basicaly the same thing it just clears your running-config thats why you should do write mem to store the changes in the startup-config.

I connected with HyperTerminal using the console adaptor and then power cycled the unit and hit the Esc key to interrupt the boot process and enter the rom monitor mode

rommon #0>

I then entered confreg command to view the current config register rommon
rommon#0>confreg
I was then asked if I wanted to make changes to the configuration register.. awnsered no

next I set the configuration register to 0x41 to ignore its saved startup
rommon#1>confreg 0x41

then reset the appliance with the boot command
rommon #2>boot

next I hasd the ciscoasa prompt back so performed the reset to factory defaults with..

enable

conf t
configure factory-default
once the restore was done
reload
confirm to save system config y
confirm to proceed with reload y
system now restored to factory settings

cheers for all your help and resources
