ASA 5505 ROMMON after erase flash

I was trying to erase some bad test configs on my 5505 with a write erase, but all VLAN and Ethernet configs remained.  I hastily decided to do an erase flash.  No I'm stuck at a ROMMON prompt with no image found to boot I'm hoping I don't have to TFTP a factory image.  How do I find the images on disk0 and copy them?

Hello Armand,

Okay do the following:

Get into the configuration terminal mode and change the config-register

asa(config)#config-register 0x01

Then, save the configuration! reload and let me know

Hello Armand,

You already erased the flash so your disk:0 is completely blank, I am afraid the TFTP server will need to be setup in order to have the ASA back up and running,

Let me know if you need a document to proceed with the rommom procesure to upload the image via TFTP

Hope I could help,

Regards,

Julio
