I've using linux (mainly kubuntu) since dapper, so I'm quite comfortable with it by now. However, now I ran into a problem which is pretty alien to me, so I could use some help.
I'm using Ubuntu Karmic on my Samsung NC10 netbook and need to upgrade my BIOS to be able to change brightness (at least according to the wiki-page). Unfortunately there seem to be a lack of guidance here on the forums on how to do it. The best way I've found so far is to use FreeDOS, that is, making a bootable usb drive and make the upgrade through that.
The part where I'm failing is how to make freedos boot on a usb drive. Here's what I've tried so far and failed:
Using Unetbootin to create a bootable freedos. Results in an invalid opcode error and halts.
Following this guide at least boots into a DOS-prompt, but lacks the function to run the exe-file needed to upgrade.
This is what I've been trying so far and failed. I still haven't found a good guide on how to do this kind of thing so I'm suggesting that a solution to this thread should go into the ubuntu nc10 wiki so others can find it easily.
Note 1: I'm perfectly aware of the risks involved in upgrading the BIOS, but considering the situations I use my netbook in, I really need to be able to save battery life. Alas, the pros outweigh the cons for me here.
Note 2: The file I'm supposed to use to upgrade can be found here. The 11CA for DOS.
