      Hi Fernando and forum-team!

      Thank you very much for this great tutorial on „updating PCI ROM modules on AMI non-UEFI BIOS“ - it's a killer man! :-)

      I'm still running my desktop-PC with ASUS P5K motherboard (AMI BIOS v1201 running on it): https://www.asus.com/Motherboards/P5K/specifications/

      Motherboard‘s chipset is Intel P35 Chipset with ICH9 Southbridge (primary controller) and JMicron JMB363 (secondary controller) for eSATA and PATA connectors and RAID 0,1,JBOD.

      The P35 Chipset supports PCIe v1.1 (1x16 lanes and 1x4 lanes) => https://ark.intel.com/products/31916/Int...mory-Controller

      I looked into the Intel's P35 Datasheet-PDF-file on page 23 (can be downloaded here: www.intel.com/Assets/PDF/datasheet/316966.pdf ) and as far as I understand the scheme of the chipset, the PCIe slots work through the MCH ("Northbridge-chip") and not through the "Southbridge-Chip" ICH9.

      My ASUS P5K motherboard has one blue (x16) and one black (x4) full-sized PCIe-slot (PCIe v1.1).
      In the blue slot I am running a PCIe v2.0 graphics card, so I have only the black slot free for additional PCIe adapter cards.

      Here my questions:

      According to Intel's specifications and the motherboards manual, the ICH9 Southbridge supports 4x SATA 3Gb/s ports (SATA-II).
      After I found your tutorial on „updating PCI ROM modules on AMI non-UEFI BIOS“ and also have seen this video https://www.youtube.com/watch?v=SO1IRpZ29Ns (bios modding) on YouTube, I would like to know following:

      1. Is it possible to modify/update the appropriate BIOS module so that the chipset supports SATA 6Gb/s (SATA-III), this is update the firmware with newer drivers or similar?
      The SATA-Ports on my ASUS P5K 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 difference is the firmware or newer driver in BIOS-firmware that allows SATA-III.
      Or am I wrong with this assumption?

      2. Is it possible to update the appropriate BIOS module so that it supports PCIe v2.0?

      3. Is it possible to work it some other way around (e.g. with CLOVER-bootloader) and get the full SATA 6 Gb/s speed on that four 7-pin SATA-connectors on the mainboard controlled by the primary ICH9-Southbridge controller chip without using a SATA-III PCIe adapter card?

      4. If I buy and insert a PCIe v2.0 x4 adapter card supporting SATA-III 6 Gb/s (http://www.delock.de/produkte/G_89359/me...?setLanguage=en ) to the black full-sized PCIe-slot (x4) and connect a Samsung EVO 850 SATA-III SSD to this adapter card, can I use the SSD at its full read/write speed (6 Gb/s) or will the ICH9-chipset interfere and limit the speed of the SSD to 3 Gb/s?
      Has anyone of you already done such an "upgrade" of an older chipset motherboard?

      5. If I use the above mentioned PCIe v2.0 x4 adapter card supporting USB 3.0 and SATA 6 Gb/s and connect a fast USB 3.0 stick (read 350 MB/s and write 180 MB/s) to this adapter card, will the motherboard be able to use the maximum read/write speed of such a USB 3.0 data-stick?

      Thank you very much for your help.
