Hello raz3k,

Nice work! Thank you for sharing your findings with the community!

Hi guys

I have VGN-FJ57LP model of VAIO


This laptop does have ICH6M that can support ahci mode

link

This is my bios, you can extract exe file using 7zip

R0130X6.ROM

https://www.bios-mods.com/wiki/Tracing_NVRAM_Registers


I read this article for a week ,But no gain

I want to enable the ahci mode.

Can you help me?

Hello kamimoto,

I took a look at your BIOS image. Unfortunately, while your chipset may support AHCI, your BIOS image does not.

Is there an updated version of the BIOS available on the manufacturer's website? If so, it may include upgraded AHCI functionality. If you give me the link, I can check the BIOS image for AHCI.

Thanks for reply

But that was latest bios image

Thank you for checking bios though

In 2012, I used syncmos to enable AHCI on my girlfriend's laptop, a Sony VAIO VGN-CR11Z.
It came with Windows Vista Home Premium, 32-bit.
Here is the latest BIOS image for this notebook:
http://download.sony-europe.com/PUB/VAIO...161241.exe

Using syncmos I was able to do a fresh install of Windows 7 Home, 32-bit
on a new SSD in AHCI mode.

I also install Fedora Linux on a small partition and installed Grub as a bootloader.
Linux has no problem at all with booting in either IDE or AHCI mode, so this
helped me to inspect the results of using syncmos.

The problem now is that Windows 10 will not boot in AHCI mode, where Windows 7
did, and Linux still does. I had to revert Windows 7 to IDE mode, otherwise the
upgrade to Windows 10 would fail at the stage where Windows 10 was booting
for the first time.

Even after a successful upgrade to Windows 10 in IDE mode, I still am unable
to boot Windows 10 in AHCI mode, even a safe boot. Windows 10 feels
definitely slower, and sometimes hangs at boot for minutes.

This make me wonder whether there is something wrong with the settings I
used for syncmos. Unfortunately, I can't find what I used as a source, but I
still have the syncmos files I used, which I will attach to this message.

Another thing I notice under Linux is that in AHCI mode, the onboard
DVD writer is still connected in IDE mode. Is that to be expected?
Could that cause Windows 10 to fail?

Here is an lspci -vvv output of the IDE and SATA controllers while in AHCI mode, if that helps:

and pls disabled the vaio logo at bios boot.

me read the tutorial on tracing NVRAM, but me dont unterstand part "Please read this reference information BEFORE you continue with this process" and some other...i try it hard and Long time but...sorry, and many thanks for help me.

big greetz!

Hello ttehelpme,

Here are the NVRAM registers you requested (I could not find DEP or SATA Hot Plug):

Code:

HPET: [0024]
    Disable: (0000)
    Enable: (0001)

VT-x: [01E3]
    Disable: (0000)
    Enable: (0001)

AHCI: [002D]
    Disable: (0000)
    Enable: (0001)

Silent Boot: [037E] - for disabling boot screen logo
    Disable: (0000)
    Enable: (0001)
