cmspider,

Thank you for using the Dell Community Forum.

Our engineers are looking into this issue. We should have information on flashing the bio on Ubuntu systems soon.

Jesse,

that's excellent news, thanks.

The Bios issues I'm aware of (having read other forums elsewhere, and found myself)

1) start-up time - would be great if it could be a little faster.

2) low-battery alarm beeping.  Could this somehow be disabled?

3) the battery discharge rate doesn't seem to appear correctly - seems like this might be a bios bug, or an acpi driver bug.

   In ubuntu, in /proc/acpi/battery/BAT0/state, the discharge rate always reads 0.

Never attempt to flash the BIOS of your Mini under anything but DOS!!!

Numerous users have reported 'bricking' their Mini by attempting to flash the BIOS using Dell's app...

DOS is by far the simplest, safest and fastest method of flashing the BIOS of either the 910 or A90 up to the latest versions...

i too have read all alternate methods to update the bios and find it frustrating even to attempt to throw away my money, just in case i brick it. 

i am indeed trying to wait patiently for an ubuntu bios update utility.  the owness should not be on the end user.

Jesse,

I just came across another issue that may well be bios related.  Running powertop on my mini 9 shows that the CPU spends 30-40% of the time running, even when totally idle.  There is lots of discussion on launchpad about various bios acpi and apic issues that might be responsible for this.

One of the most relevant seems to be:

https://bugs.launchpad.net/ubuntu/+source/linux/+bug/177895

But this looks like it might be a huge battery life issue (like we might get lots more life if it can be fixed.  The suggestion in that thread to disable all but the first CPU (the atom hyperthreads - so it looks like two cpus) on my system allows it to spend 95% time in C3, rather than 50-60% when both 'cpus' are enabled.

Hi,

So I managed to create a DOS boot disk, downloaded the BIOS update (that says it works in either Windows or DOS) and when I run the executable it says, "This program cannot be run in DOS mode."  I'm a bit stuck.  Any answers?

It turns out that that is a windows only executable.  I did manage to upgrade to A02 using a dos-bootable USB flash drive, but its not trivial. There is a post here on how to do it (I didn't try following those instructions so can't vouch for them).

I wouldn't try it unless you are confident you know what you're doing.

I ended up finding this on the Ubuntu forums:

As with the solution you posted, it was not for the faint of heart.  Btw, the instructions don't mention it, but to extract the files from the A02 windows executable you can use wine and get the files from ~/.wine/drive_c/windows/temp/WINPHLASH/

The method pgoodall referenced worked well for me.  You're simply using the dos flash utility from the earlier BIOS code with the new ROM file from the current BIOS code.  I was more comfortable with this than other methods.

The biggest trick is making a bootable USB drive if you don't have any computers with floppy drives, but there is plenty of info around the net to help with that.

Can the bios.rom file in the exe file be installed with the standard dellBiosUpdate program as described here?

It's really ridiculous that Dell has not come up with Linux solutions for updating thie BIOS when they ship the product with Ubuntu.  Why don't they include all of their standard Linux tools like they have for their other systems?
