ASUS P5K - BIOS mod for SATA-III-support (SATA 6 Gb/s)

[Lemmy1980]

Hey guys,

I'm an average PC-user with basic BIOS knowledge/understanding, and I'm still running my PC with ASUS P5K motherboard (AMI Bios running on it) => Intel P35 Chipset with ICH9 Southbridge: https://www.asus.com/Motherboards/P5K/specifications/

I want to thank "camiloml" for enabling/activating AHCI on the primary Southbridge (Bios version 1201) for ASUS P5K motherboard (https://www.bios-mods.com/forum/Thread-s...os-for-SSD).
I appreciate your help a lot! :-)


Here my request:
-----------
According to Intel's specifications the ICH9 Southbridge supports 4x SATA 3Gb/s ports (SATA-II).
After I have seen this video https://www.youtube.com/watch?v=SO1IRpZ29Ns (bios modding) on YouTube, I wanted to ask you following:

1. Is it possible to modify/update the BIOS so that the Chipset supports SATA 6Gb/s (SATA-III) - update the firmware with newer drivers or similar?
The SATA-Ports on my motherboard are (physicaly and technicaly) the same as on newer motherboards (e.g. motherboards with Q77, Z97 Chipset and later), so I thought the only differece is the firmware or newer "driver" that allows SATA-III-speed. Or am I wrong in my assumption?

I am fully aware of the fact, that SATA interface has it's technical limit at 6 Gb/s (SATA-III), and that is the reason why the industry switched to PCIe-interface for future SSD technology.

I have read that Hewlett Packard sold notebooks in year 2008 (HP Compaq 8510p) with PM965 Chipset with ICH8M Southbridge, which normally supports SATA 3Gb/s, but HP limited the SATA-speed to 1,5 Gb/s in the BIOS (for different reasons)...


2. Is it possible to modify this old AMI-BIOS (ver. 1201) so that the motherboard supports NVMe protocol? 
Or is NVMe support only available on motherboards with UEFI-Bios?

Thank you very much for your help,
Ozzi

Hey guys,

after days of searching the web I found the "answer" to my question no. 2 (NVMe support for older motherboards) here, and it seems to work without modding of BIOS:

Some further explanation from the same forum:

I just wanted to share it with you - maybe somebody was just looking for such a solution :-)
