Hi all

I wonder if some one could point some where, where I can find out how to find the zip header in a ASA image. My quest is to get at a minimum asa804 working. I have found post on how to extract asa821 which I can do but the asa keeps rebooting with ERROR -9.

I have managed to get asa821 to pickup 6 interfaces but still its rebooting, so i want to try a lower asa version that might not have these issues.

Any help or tips will be greately appriciated.

Below is the zip header for asa802 and 821..... hope fully we can extend this list

asa802-k8.bin ---> tail -c 13334352 asa802-k8.bin > asa802-k8.gz (1228B0)

asa803-k8.bin ---> tail -c 13444944 asa803-k8.bin > asa803-k8.gz (1228B0)

asa804-k8.bin ---> tail -c 12947265 asa804-k8.bin > asa804-k8.gz (1228BF)

asa805-k8.bin ---> tail -c 12743983 asa805-k8.bin > asa805-k8.gz (122AD1)

asa821-k8.bin ---> tail -c 15083928 asa821-k8.bin > asa821-k8.gz (122E68)

asa822-k8.bin ---> tail -c 15083246 asa822-k8.bin > asa822-k8.gz (150112)

asa831-k8.bin ---> tail -c 14510704 asa831-k8.bin > asa831-k8.gz (15dd90)

Extract 804 kernel:

1. Download hiew
2. Run hiew, and then open the asa804-kb-bin file
3. press F4, select hex mode
4. press F5, enter 17000, the cursor position will jump to 66 EA 08 00 ..
5. Then pres shitf +8 (*), that is to start marking
6. press F5, enter 1228be, this is to select all the data you want to save. in otherwords this is the kernal data, and then press Shift +8 (*) to complete the marking.
7. Press F2, in the "file:" option, type, file path of the output, such as c:\asa804.kernal, press enter, and then in the "offset:" type 0, press enter, press enter again.
8. now the asa804.kernal file will be in c drive


Hope this easier to understand.

Thank you ! Thank you so much !
When I tried to unpack ASA image with Cisco unpacker, I got an error "Couldn't find any ZIP header in asa8XX-k8.bin", except ASA802. I was confused, and did not know why.
I searched all forums and websites how to unpack ASA image, and it seems that a lot of people have run into the same problem I have. I tried every solution I found, but nothing change.
Until I found this guide "http://ers.msk.ru/cisco/pix7-asa8.html", but again, it works with ASA802 only. And so lucky I found your post, it is great!
Thanks oracll33!
