Bios Update

Hi,

I Built my first PC over a year ago and everything has been fine.

I was looking in the BIOS the other day and noticed my version was really old

The old one my system was 0915 and the latest one that Asus had on their website is 1503.

So I decided to try and do the flash and update it…. I know many people say it is risky but I felt comfortable doing it…..

Everything went fine and the BIOS is now updated to 1503. :)

HOWEVER, I've encountered another problem…..

When I open up my Samsung Magician you can see in the System information that the SATA interface is not detected and the AHCI mode is deactivated….

So I went back into the BIOS and it was set to IDE…..I changed it back to AHCI mode and exited the BIOS….

But now when I open up the Samsung magician it’s the same as before…Nothing has changed…..

How do I get it back so that the SATA interface is detected and the SSD is in AHCI mode ? ?

what has happened ? I tried reinstalling magician.

Reinstalling Magician Didn't work..... "

After reinstalling magician, I went back into the bios.....I changed it back to IDE mode then saved and exited..

Then I went back into the BIOS again and changed it back to AHCI mode and saved and exited.

Samsung magician still says, " SATA interface is not detected and the AHCI mode is deactivated "

I'm also curious in the above 2nd picture where it shows its in AHCI mode, why cant I see the SSD drive..... ?

You can see the Asus DRW.....but everything else says not present ?

Very confused now.......
 
What motherboard do you have? When its in Ahci mode can you access the drive in windows?
 
I don't know how to solve your issue, but I will mention that most times you do a bios update, it sets everything back to default afterwards unless you're given an option to not to set everything to defaults.
 
As above, flashing BIOS will clear your settings (reverting back to IDE).

I'd double check with something like CrystalDiskMark or CrystalDiskInfo that can tell you which driver is active on the drive. If you have something like msahci or similar then it's using AHCI and the error is with Samsung Magician.
 
I would say you are fine. I had an Asus motherboard years ago running AHCI and the bios wouldn't show the hdd either, but it would show the dvd drive. As long as it works, its good.

Hi,

Yes, the computer is running fine, but how do I know that I'm getting the full potential of my SSD....

If I believe what it says in the magician software, Im not getting the full potential....

Prior to the bios update all the details in the Samsung magician software was fine
 
How to enable AHCI in Windows 7 after Instalation:

There is one way to fix this, although you need to have knowledge of registry editing. The detailed steps from Microsoft are as follows:

1.Exit all Windows-based programs.
2.Click Start, type regedit in the Start Search box, and then press ENTER.
3.If you receive the User Account Control dialog box, click Continue.
4.Locate and then click the following registry subkey:
HKEY_LOCAL_MACHINESystemCurrentControlSetServicesMsahci
5.In the right pane, right-click Start in the Name column, and then click Modify.
6.In the Value data box, type 0, and then click OK.
7.On the File menu, click Exit to close Registry Editor.

After this you’ll have to restart your computer, go to BIOS and enable AHCI. When you log in to Windows again, you’ll notice the installation of drivers for AHCI. Another restart will be required to finish the driver installation.

These steps are provided at your own risk and not suggested unless you know and understand the risks. You will want to make sure the controller driver and MB BIOS support this option before you enable it

Also, download ASssd and verify you have correct alignment. Look at the left and it should say 1024 ok or some number ok. If not you are not aligned. http://lifehacker.com/5837769/make-...ned-for-optimal-solid-state-drive-performance

Microsoft Fix it 50470 seems to be for errors and you don't have any errors, but here's the link anyway.

It does the very same thing you gave him instructions for with out worrying about (These steps are provided at your own risk and not suggested unless you know and understand the risks.)


This issue occurs if the disk driver in Windows 7 or Windows Vista is disabled. This driver must be enabled before you change the SATA/RAID mode of the boot drive.

Thanks,
Those instructions seem pretty straight forward. However, after step 7 you say to go back into the BIOS an enable AHCI mode.....

It is currently in AHCI mode

If that step is already done then skip it.
 
Windows 8 uses a different reg key for ahci.

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\storahci

Hi Again,

I was going to try and follow those steps to fix this problem, but then I read:

" You will want to make sure the controller driver and MB BIOS support this option before you enable it "

How do I find out those 2 things ?
 
Your board supports it so don't worry. He copied and pasted that from a website. They did that for older model motherboards that may have windows 7 installed but don't support ahci mode.
 
Still no closer to fixing this ....

I followed the below steps:

1.Exit all Windows-based programs.
2.Click Start, type regedit in the Start Search box, and then press ENTER.
3.If you receive the User Account Control dialog box, click Continue.
4.Locate and then click the following registry subkey:
HKEY_LOCAL_MACHINESystemCurrentControlSetServicesM sahci
5.In the right pane, right-click Start in the Name column, and then click Modify.
6.In the Value data box, type 0, and then click OK.
7.On the File menu, click Exit to close Registry Editor.

When I got to number 6, it ALREADY has a Zero in the value data box..... Next to the data box there is an option to select either decimal or hexadecimal....its currently selected as hexadecimal....is that what it should be ?
 
Doesn't mater if it's set to decimal or hex. A 0 in either number system is still 0.
