Acer Aspire T310 Jumpers

Hello

I Want to disable the Onboard SIS Graphics in my Acer Aspire T310 as an additional AGP card doesn’t seem to work.

There is no option to disable the graphics in the BIOS, although there are several Jumpers on the Motherboard. Jumpers JP1 and JP3 are documented, both on the board and on the Acer site, but there are also several other jumpers, namely J1, JPT3, JP4 and JP5.

Does anyone know if any of these are for disabling the onboard graphics?
