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-brief.pdf 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?
Hello! You can suggest something on the topic, maybe I created a topic in the wrong section, here sometimes people mention the BIOS in this section and the processor section is only there.
You can delete my message later so that it does not violate the order here.
Thank you for contacting Intel Embedded Community.
You need to consider that the Bay Trail processors are no longer supported, as you may confirm on the following website:
By the way, we want to clarify that the Intel Atom® Processor Z3740 is a non-embedded device, as you may confirm on the following website:
Also, the non-embedded processors are supported under the following channel:
Yes that's right. Then I originally wrote a post in the correct section, with the correct mark. Since you have no commitments and plans for this series of processors, I think you could provide some documents on writing a BIOS(537531 and 537532) for this dated Atom Z3740 SoC, for an enthusiast user who wants to take advantage of the declared potential of this wonderful processor.
Thanks for the clarification.
