I agree, could not find list of changes. I wish they could ad a way to slow down the power supply fan. Its too loud.

all the information they give you :

Alienware Aurora Ryzen Edition System BIOS | Driver Details | Dell US

nothing to be honest

Just updated mine, still working like a charm.

But I agree, having a list of bugfixed or improvments could be fantastic, especially that we go from 1.x.x to 2.1.0, i guess those are major upgrade, or maybe some testing for the R11 if they use the same mother board

After I installed this BIOS version on my Aurora r10 Ryzen Edition the AC Recovery Mode stopped working.

Before that Update I had it on "ON", and The PC started as soon as I gave him Power from my Smart Home Power Plug. Now it doese't work anymore... I can turn it ON or put in on Last State, i dosen't matter PC won't boot automaticly. I need to turn it on by hand. I know it sounds not like a big problem but i like it when i come home from work and just need to turn on one switch for my whole gaming room and dont need to turn the PC extra on by hand.

Maybe someone has the same issue? or any ideas what i could do? beacause Alienware blocks me to downgrade this version.

Better then what I experienced. 

2 days in a row my pc powered on itself. 

I don't use sleep mode.. Only happened after 2.1 bios 

From Dell's website:

With the R10 now officially being sold with zen 3 (5000), the prospects of a BIOS update becoming available for R10 zen 2 (3000) owners soon looks like a possibility.

The only thing you need to know:

- it still uses OLD agesa lib, so no ryzen 5xxxx

- it still doesn't support xmp 2.0 3600 so you have to specify timing manually

as a bonus it can't be installed with alienware update (it just stuck)

meaning dell at its best :(((

Mine hung also when trying to update the bios using the Dell update app. Rather scary, since I did not know if that would result in a bad flash upon reboot. Had the foresight to download the manual bios updater and ran it right after that before a reboot. Slow flashing process had me concerned, because there's no bios flash back or dual bios on this board. You think for $3,600 regular price it would have good bios recovery options.

I ended up flashing back to the previous version, because the memory settings in the bios were available but locked out. It auto selected XPM2, but I could not change to anything else, including manual timings.

Since I am planning on maybe upgrading this slow 20-20-20 (HyperX without the hyper) to faster 16-18-18 I need those settings unlocked in case I need to manually change timings.

Flashing back worked, but again very slow bios flash sequence. Always scary to flash a bios without having a good recovery option and a slow flash process. The longer the process takes the longer you are exposed to a bad flash since power can unforeseen fail at any time.

The auto updater should never hang during a flash, since the whole point of having that program is to have an easy method to update your system. Obviously not tested well on their end before rolling this out.

Also should be a change log available so we can see what has been updated, or downgraded.

===========================

Yeah, a back-flash is always risky. The intel-based machines should have Dell-BIOS-Guard (but not sure how good it works).

I would only update BIOS from boot-screens (actually the UEFI boot environment) with flash-drive.

Interesting to see this BIOS in v2.x already. However, at least they are trying and still working on it.
