I want to disable the onboard graphics on my Acer Aspire T310. There is no option to do so in the BIOS.
The motherboard has several jumpers, namely JP1, JP3, JP4, JP5, JPT3 and J1.
JP1 and JP3 are documented on the board and on the Acer site as the BIOS write protect and CMOS clear.
Does anyone know what the others do and if one of them disables the onboard graphics?
