    Hi,
    the friend of mine has the R700VM from ASUS that was bought around the 4Q2012 - ASUSTeK Computer Inc. -Support- Drivers and Download R700VM that was recently subject of upgrade by adding the Samsung's EVO 840 (250GB) SSD drive - Samsung SSD (Solid State Drives) 840 EVO | Samsung SSD UK.
    Suddenly the problem of the ASUS's motherboard implementation based on Intel HM67 raised right after the SSD/EVO 840 SATA3 was plugged in there.
    The disk is fine itself (tested on some other notebooks with no issues), but inside the ASUS'es R700VM it's basically very unstable - Win7 BSODs, it boots randomly with only about 20% of attempts, etc.

    From network research it looks like ASUS has failed with the SATA3 support implementation at their MOBO and probably their backward autoswitching for SATA2 is buggy that brings the unstability.

    My friend can not afford another SSD disk or new notebook right now, so the question is, how to fix it in place:
    - how to edit the ASUS's BIOS to make it working stable with the EVO on SATA2 mode (preferred approach - how)?
    - or eg. could we try to slow down the EVO to SATA2 only, by the SSD's firmware modification (how to make that happen)?

    1.
    Please advise, how to extract, edit and flash back the ASUS R700VM's BIOS, to change it's AHCI controller mode to be permanently announced as SATA2 capable only for any system/OS, that we believe - it should at least allow us to have it working fine with any SATA3 SSD drive (in our case the EVO840) by slowing it down permanently on initial interface negotiation to SATA2/3Gbps transfer rates (we are fine with 300MBps R/W)?

    2.
    If the option 1) would not be possible, please advise, how to extract and edit the Samsung's EVO840 firmware, to disable it's SATA3 option and make it permanently SATA2 drive alike that could help operating properly with the crappy ASUS R700VM AHCI implementation.

    3.
    any other ideas?


    Regards,
    NU.
