(Update of 2020 06 09 with version 18.104.22.168 and version 4.0.30 legacy branch)
We are often asked how to update the BIOS of the APU PC motherboard.
This consists of downloading TinyCore, flashing it on an SD card, then downloading the desired BIOS and copying it to the SD card.
When you have several versions of APU card namely 2, 3, 4 or 5, you have to make several downloads.
It also happens to want to go back to a previous version or to the old "legacy" branch. When you want to flash a new or old BIOS, sometime there is no access to the internet or with slow internet access.
At Rack Matrix Technology, we made an SD card that contains all possible BIOS versions to be able to flash the desired BIOS quickly. This card is very useful on our assembly line, to flash the right BIOS required by customers.
So we decided to share the contents of our SD card used to update the BIOS of all APU cards.
The peculiarity of this card is that it has as much file as APU card model and also the files of the branch "legacy". In each folder there are all BIOS versions published from the beginning. The advantage is that you can choose the BIOS version according to your needs.
