Repair/replace BIOS On A Specific Acer Aspire One

The following chat involves interfering with the most important functions of your computer. Since these are hacks, you should not run it on a running computer unless you are prepared for things to get worse, void your warranty, or cause your computer to crash beyond repair. If the realization of these risks bothers you, you can hire a professional to help the person instead of taking the next available steps yourself.

Extremely poorly assembled, in my case the valve workedtor.

Identify network system devices.
Describe the roles of each firewall.
Understanding Cisco certifications.
Use the ipconfig, ping and hence traceroute commands.
Check basic network connectivity.
Have enough knowledge to participate in more advanced learning.

This appears to be a minor issue with the Aspire One, and also system independent (search shows there are solutions for Windows as well). I suspect that reformatting and shaking the partitions on my hard drive during installation didn’t work for most Jaunty. But it won’t be related to Ubuntu.
