Dell :: BIOS Hack To Enable Intel VT And/or AHCI On Inspiron

Nov 20, 2009

when I got my 9400/E1705 I was always sad for not having the AHCI option available in the BIOS.

This was asked for so many times:

- "Notebooks BIOS should support AHCI"
[url]

- "Enable AHCI in Dell Notebook BIOS"
[url]

- "Please give us BIOS support for SATA AHCI mode on Inspirons!"
Please give us BIOS support for SATA AHCI mode on Inspirons!

- "Give us real bios control"
[url]

- "Bios release"
[url]

In the Sony forum, they have found a way to activate these options even if they're not present in the BIOS:

How to Enable Intel VT and AHCI on a Napa/Santa Rosa platform Phoenix BIOS Vaio laptop
...
The only item you'll need is a bootable DOS media. Click one of these links for instruction for creating a bootable floppy disk (with USB floppy drive) or usb stick.USB flash1 or USB flash2 or CDR (add modified table file to image before writing).
Instructions:

1.Download symcmos and copy it to your bootable DOS media. This utility is used to modify your Phoenix BIOS settings. Also, download a DOS text editor and copy it to the media if you feel comfortable editing a file in DOS.

2.Go to the BIOS by pressing F2 during start-up, or when the VAIO logo appears, and reset the settings to factory default. Save and reboot.

3.Go back to the BIOS and enable the boot from external devices option. Save and reboot.

4.Press ESC when the VAIO logo appears to bring up the boot selection menu and select the bootable DOS media. At the prompt, type "symcmos -v2 -lDefault.txt", without quotes, and note that there's no space in between the flag and filename. This will create a literal symbol table from the NVRAM named Default.txt which contains all the current BIOS settings. Reboot by pressing Ctrl+Alt+Del. If that doesn't work, hold the power button until the notebook turns off.

5.Use the DOS text editor (or boot to another OS and use a text editor there) to edit the generated Default.txt file. Change the following lines and save the modified file to something else (e.g. modified.txt):

For Napa SZs - R0112N0

AHCI: (015C) [0000] ---> (015C) [0001]

VT-x: (0354) [0000] ---> (0354) [0001]...

Sony :: Howto Enable VT On Vaio Z *tested*H2 Bios Hack

Oct 5, 2009

I`m very happy to have found a way to enable VT.

If you doenst know what VT is - YOU DONT NEED IT ^^

At first i was a little bit afraid, to take the risk to hack the Bios, but finally i take it.

Not only VT works now fine, also the advanced Bios Setup Screen, let me finetune everything i ever dream from. You could tweak many things, dont do there anything, if you doent know what you do.

Ok, back to Topic:

After some Internetresearch i found this link:

[url]

Please follow the instructions exactly. I have do also the same reverse for testing - you could go back, if you want.

But: with every Bios tweaking - you lose your warranty.

Here my Statement on this Blog. PLEASE, look there there if your Model is supportet - FIRST.....................

HP Envy Dv7 7304tx :: How To Enable AHCI Mode (which Is Not Possible In The BIOS) To Optimize The SSD

Nov 25, 2014

I have an HP ENVY dv7-7304tx now succesfully running a Samsung 840 Evo SSD as the primary disk. The second disk is the original spinning disk.
 
Samsung Magician software tells me I need to enable AHCI mode (which is not possible in the BIOS) to optimise the SSD.
 
Does this have the same or similar solution to that provided in the link here? : [URL]....
 
Would there be any negative consequences for the spinning disk?

HP Envy SleekBook 6-1153eo OS/Software :: Enable AHCI In Windows 8 / BIOS

Feb 14, 2013

My computer:
HP Envy Sleekbook 6 - 1153eo
Windows 8 Pro
 
AHCI is currently disabled on my computer and I wish to enable it to get the most performance out of it. It can easily be enabled via the windows registry but to get it working i need to be sure that AHCI is currently enabled in the BIOS aswell. When I enter the BIOS there just isnt any advanced options available, only time and date and other basics. How do i find out wether or not AHCI is enabled in the BIOS? How do i get access to the advanced options in the BIOS to turn on AHCI (if it isnt already enabled that is)?

Dell Inspiron 1720 :: Difference Between ATA And AHCI Settings For SATA Operation In BIOS

Aug 31, 2007

I just got my new 1720 Inspiron, and I had a problem when trying to create an image of the C and D drive using the Ultimate Boot CD (BART), it would never see my hard disk partitions.  I changed the BIOS setting for the On Board Devices from AHCI (default) to ATA for SATA operation.  I also had to change the Flash Cache Module to be disabled, it was enabled in the Factory Default.  The result of these changes was good, I was able to see my C and D drive when booting from my Ultimate Boot CD. What these changes do?  Should I leave my BIOS at the new setting, or will I lose performance from my hard disk?

HP Envy Dv7-7398ca :: Enable AHCI Mode On Notebook With SSD

Aug 12, 2011

Year old i7 Envy Dv7-7398ca notebook with Samsung 840 Pro x 256 SSD.  Windows 8.1. I updated to the  SSD soon after I purchsed the notebook.   
 
No issues except the Samsung Magician SSD software keeps flagging me that AHCI mode is disabled and needs to be enabled and I do not see it in BIOS. Nor do I see anything that relates to it in Device manager like IDE or whatever. 
 
It appears the SSD is not optimizing itself based on the fact it thinks AHCI is disabled.

Acer :: AMD Vs Intel X64 Support For SATA/AHCI

Aug 9, 2008

Acer Extensa notebooks usually come with SATA drives. However, my impression is that models with Intel Core 2 Duo CPU's have built-in SATA/AHCI support in Vista, while AMD Athlon 64 X2 models do not:

- Device Manager shows the drive and controller as IDE/ATA, not SATA, even when the drive is SATA;

- there is no option in BIOS (even latest version) for switching from ATA compatibility to SATA/AHCI

It looks like AMD does not support SATA/AHCI, while AMD does not.

HP/Compaq :: Enable Intel VT On Pavillion DV2842SE

Sep 15, 2009

I want to enable Intel VT on my HP Pavillion DV2842SE. I need to do this to run a 64 Bit Guest OS in VMware/Sun Virtual Box. Currently, the Phoenix BIOS (version F2E dated 12-2008) hides this feature. I have tried flashing to older BIOS versions just in case with no luck. My Proc is Intel Core 2 Duo T 5600, Mobo is Wistron 30CD, INtel GM 965 Chipset, 4 GB RAM, running Vista Home Premium 64 Bit. I had previously installed XP Prof 64 Bit on this laptop and got Intel VT turned on(so it is clearly supported), but cannot do it when I returned to factory installed Vista Home Premium 64 Bit (some software was not available for XP like Youcam and Multi-Touch scrolling for trackpad,etc and so I had to (sigh) return to Vista).

Lenovo ThinkPad W Series :: W540 - SATA Option (RAID Or AHCI) Gone After BIOS Update To 2.05

Feb 6, 2014

W540 20BG001CGE, had BIOS 1.05 and RAID 1 with two Samsung 840 EVO 1TB working fine under Windows 7 - x64. Did a (by lenovo update tool recommended) BIOS Update with the bios update manager to 2.05. Update ran fine. After Rebooting (and loading defaults, disabling Intel Rapid Start, Changing BIOS boot option to legacy first ... I recognized SATA Option (AHCI or RAID) in BIOS is gone. At boot Intel Matrix Storage Configuration doesnot appear anymore (where you can build RAID etc).
 
Boot then brings up message "missing operating system".
 
Downgrade to BIOS 1.05 impossible, due to ISO File on www.lenovo.com support is not system compatible, message "Lenovo Group Limited - Invalid system disk; Replace te disk, and then press any key")
(The link to the ISO File version 1.05 at the bottom of this page links a non bootable ISO image [URL]....)
Also the downgrade to BIOS version 1.08 found here [URL] .... does not work, CD also messages "Lenovo Group Limited - Invalid system disk - Replace ...").
 
Rewriting BIOS version 2.05 (GNET57WW) does not work (says "BIOS update not necessary").
 
Embedded Controller Version GMHT25WW (1.10) ME Firmware Version 9.0.22.1467. How to get back my RAID controller?

Dell Inspiron 11 :: Upgrade To SSD Will Not Work In AHCI Only In ATA?

Jan 7, 2015

I have a Dell laptop Inspiron 11 3000 2in1. I decided to swap my Dell Sata 54000 rpm HD to a SSD M500 240GB. I went in the BIOS and it does recognize the Fixed HDD - Crucial_CT240M500SSD1 240GB. I tried installing Windows 8.1 and it would not recognize the SSD HD. What I notice if I go in the BIOS and change SATA Operation to ATA it works fine. I would like to have it on AHCI because I guess that is the latest technology for reading a HD. Any reason why I can't install it with AHCI? It also did work fine before on AHCI with the factory HD that came with the laptop.

Dell :: Inspiron 1545 Sata Drive ATA / AHCI

May 25, 2009

got a inspiron 1545 recently with a SATA 320 gb HDD / 4gb ram with Windows Vista Home Basic. Like most of us I hate Vista. So I created a partition & installed XP.

Used a program "EasyBCD" to setup dual boot. I get the dual boot screen at startup. But only XP boots. After a little probing, came to know that there are only 2 options in the BIOS for SATA operations. AHCI & ATA. If I select ATA I can boot only to XP. If I select AHCI then I can boot only into Vista. Searched around but the solutions were a bit over my head. Really appreciate if anybody could come up with something in lay mans terms.
