I have tested ZorinOS 9 and ZorinOS 15 Ultimate 64 bit, they are Ubuntu-based and working. Windows 7 Ultimate 64 bit works, too.
MacOS 10.5, 10.6 and 10.9 are also working perfectly with the integrated GeForce. Even sleep is working which is usually the biggest problem.
Well, in Leopard I'm loosing NVidia LAN after sleep, but this is solved by an Atheros 5212 WLAN card. So the PCI-E slot is used.
I also want to use the board for AROS, an AmigaOS-based operating system. It mainly used old nvidia cards, the 9300 chipset is supported. That's why I'm not using a PCI-E gfx card.
Ok, I'm not interested in using the highest version number if it will work. Android 7 is Nougat, what about Android 8 Oreo?
