Default Re: Acer LA-H782P-Rev:2.0

Just to complement the picture about onboard memory disable.

The schematic shows the truth table for no memory as:

RAM_ID0 = 1
RAM_ID1 = 1
RAM_ID2 = 1
RAM_ID3 = 1

So you must have RC150, RC151, RC153, and RC224, populated with 10K
And RC155 RC225 RC226 RC227 not populated, to disable the ram.

The resistors changes will be different for the different boards IDs and for the different possible memorys IC brands.

SMDFlea thank you very much, this boardview saved my night. ;D
