I have created this thread so that I can post all of the information that I have figured out about my notebook and its motherboard. I am going to be making modifications to this post/thread as I gather more information about my notebook. I will also be uploading more pictures over time. This thread is an ongoing work in progress.
Admins, please do not modify my thread yet as I have not made enough progress for this thread to be considered even somewhat complete. I just posted a few details at the moment to get the thread started. If you feel that a modification is necessary, please PM me and I will make the modification accordingly. I usually check PM's a few times per day at minimum.
This thread will be divided into sections and sub-sections. There will be three main sections (Basic/notebook info, BIOS info, & General Motherboard info). The BIOS section will have many sub-sections including a large list of discovered NVRAM values found by investigating TEMPLAT0.ROM and STRINGS0.ROM.
If you are looking for a schematic for this exact revision of the board, I do not have one. I can link you to schematics of other closely related revisions of this board, but they may or may not be useful for this custom Sony board.
