I was referred here by Intel support after requesting access to the GM45 BIOS Writer's Guide. How would I go about obtaining access to that document?
We have a client here that would like some BIOS development work on a GM45 chipset (DDR2 RAM initialization), but we need the chipset documentation to proceed.
Please refer to the following documents:
http://www.intel.com/assets/PDF/datasheet/320122.pdf Mobile Intel Series Express Chipset Family (contains information about System Memory organization support for DDR2, page: 61).
http://www.intel.com/content/dam/doc/datasheet/io-controller-hub-9-datasheet.pdf Intel® I/O Controller Hub 9 (ICH9) Family (contains information about initialization, DRAM Initialization Bit, page: 490).
http://download.intel.com/design/intarch/manuals/320276.pdf Intel Core 2 Duo Processor and Intel GM45 Express Chipset (with DDR2 System Memory) (Development Kit User's Manual).
http://www.intel.com/content/dam/doc/product-brief/mobile-gm45-intel-gs45-gl40-express-chipsets-brie... mobile intel Gm45, Gs45, and GL40 Express Chipset for embedded computing (General information about Bios and OS specifics).
I hope this information is useful.
Unfortunately those documents do not detail the Intel-recommended DDR2 training sequence. It is my understanding that there exists a "BIOS Writer's Guide" for that chipset and/or CPU, but that it is a confidential Intel document. How would I go about requesting access to that document from Intel?
We have escalated this to the account manager, greggzeutzius, and the application engineer, Peter, so they can further assist you.
