Ubuntu Flash/Update BIOS with Firmware-tools

Hello, I need to update (flash) my BIOS using this guide: http://linux.dell.com/wiki/index.php/Repository/firmware#Putting_it_all_together

I'm using Ubuntu 8.10 Server on Dell Dimension 3000

I've followed the instructions, I think 'all' went well...

I get "Couldn't find any package whose name..." but I think  thats normal, right?

So, thinking all is going well, I run:

--------------------

root@server:~# update_firmware

Running system inventory...

Searching storage directory for available BIOS updates...
Checking System BIOS for Dimension 3000 - a02
    Did not find a newer package to install that meets all installation checks.

This system does not appear to have any updates available.
No action necessary.

--------------------

As you can see, I'm trying to update an old Dimension 3000 - a02 to a03. I don't think its in the Repositories but it is available to download from Dell Support as seen here:

So the question is, what can I do? I'm sure someone needs to add that BIOS image to the Repositories....

Thanks for your time,

Trevor.
