GM45 BIOS Writer's Guide

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!

Hi Timothy,

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).

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,
