Hello and welcome to the Intel® Embedded Community.
Here are a few pointers that might help you:
1. BIOS specifications for Huron River platform in Intel® Embedded Design Center (edc.intel.com). However to access most of these specs, you need to be a Privileged member of the Intel® Embedded Community. If you are not already a Privileged member, you can request an upgrade to your community account here:
2. Intel e-Help dek. As a privileged member you can access the Intel® e-Help desk which is staffed by Intel representatives who support select Intel embedded platforms including Huron River.3. Are you working with a BIOS vendor, e.g. such as AMI ? If you are not already an expert on porting BIOS, you might want to consider working with vendors that specialize in that technology.You can find BIOS solutions offered by members of the Intel® Embedded Alliance (Intel's embedded ecosystem) at this link:https://www.intelcommsalliance.com/kshowcase/view/catalog_search?product_categories%3Alist%3Aiso-8859-1=Operating+Systems~BIOS%2FBIOS+Replacements
I hope this helps.
