GM45 BIOS Writer's Guide

[TPear3]

Hi all,

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.

Thanks!

Hello,

Could you please tell us the ICH's s-spec number and the processor's s-spec number.

Thanks!

Jimmy.

Hi Timothy,

Please refer to the following documents:

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).

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?

Thanks!

Hi Timothy,

We have escalated this to the account manager, greggzeutzius, and the application engineer, Peter, so they can further assist you.

Best,

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.

Hello, @Vlares:

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:

https://www.intel.com/content/www/us/en/support/articles/000022396/processors.html

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:

https://ark.intel.com/content/www/us/en/ark/products/76759/intel-atom-processor-z3740-2m-cache-up-to-1-86-ghz.html

Also, the non-embedded processors are supported under the following channel:

Best regards,

@CarlosAM_INTEL.

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.
