Hi Dave,

Just figured out what the error was. It is to do with creating the FLASH memory.

You’ll need to run the following command:

qemu-img create FLASH 256M
Formatting ‘FLASH’, fmt=raw size=268435456

Once the FLASH is created move it into the asa802 folder.

This is based on henrydu.com website:

Hope this helps.

With all due respect, it is a very nice tutorial and fairly straightforward to follow.
However, it does not work..!!
All I get is the same as Allan, a console connection with a hash prompt. If you try and run the commands:
cd /mnt/disk0
/mnt/disk0/lina_monitor

the response is that there is a memory error.

Is there anyone out there that has actually managed to get this to work..??

I have been on several forums and they are all full of advice and instructions and I have asked this question over and over for multiple platforms.

No one has responded in the positive..!!!
