This is a simple guide on how to easily reset the BIOS of Voyo Mini PC. I messed up some settings in BIOS the othe day, as I was trying to install also Android, and somehow I disabled the USB support in BIOS, so I had to reset BIOS to default settings.
If you want to do that, you have to download first 'Voyo Mini PC BIOS' archive from here, here or here. (2,44 MB) I advise everyone to make a copy of a working BIOS, if possible, before doing BIOS experiments. To do that you can simple use the provided afuwin-5.05.04 software. If you disabled USB in the BIOS, just like I did by mistake, only overwriting NVRAM can reset BIOS settings. In this way, there is no need to open the case, to teardown Voyo Mini PC, to reset the CMOS. All the actions are made from Windows environment, so your Mini PC has to be able to boot into Windows. All the following actions that are you will do next are entirely at your own risk.
Archive name: Voyo Mini PC BIOS
Archive size: 2,44 MB
Archive content: afuwin-5.05.04 (afuwin32 & afuwin64) & Voyo_mini_PC_Bios_Backup_25.03.2015.rom
For flashing NVRAM:
1. Download the above archive. It is better to extract the content to the disk C.
2. Open as administrator Afuwingui.exe \afuwin\32\AfuWin32\Afuwingui.exe.
3. Open original backuped bios. Uncheck default 'Main BIOS Image' and check only NVRAM box. Press Flash. And best of all, start a command prompt as administrator and type, for example: C:\AfuWin32\afuwin.exe BIOS.rom /N
4. Press exit and restart the PC. After boot go into the BIOS and reset settings to default.
I tested myself and everything worked like a charm. Now my Voyo Mini PC BIOS is back to default settings.
