This is for A09 BIOS (My mini-10 came with A07 BIOS)
I ran the BIOS updater in Windows, I couldn't find a good guide to use the DOS updater.
The windows updater showed 18 blocks being erased and rewritten individually, in the GUI updater. (I think there were 18 blocks).
When it was all done, (the updater) said it would reboot automatically.
It didn't. I waited about 10 minutes.
Then I decided to close the window, my USB mouse still worked, but the keyboard didn't.
The application hung up. I waited a long time to see if it would close, it didn't.
Since my mouse still worked, I used the menu to reboot my mini.
It rebooted and everything seemed fine. The WiFi radio was turned off, so I used the app to turn it back on.
My mini also did a funny thing in Linux 7 Mint. When I wanted to log off of mint with the power button, I got a dialog saying "user has no permission to log off"
So I used the menu to log off. That worked fine. Upon a reboot, the power button reverted to working like it did before I upgraded the BIOS.
(power button in Mint takes you to log-off screen)
Everything else seems fine today. I checked the BIOS screen and it is listed as version: A09
