Ello. I wanted to know if there is a BIOS update for the Aspire M1100 because my BIOS dated 23/02/2008 which references are Motherboard SMBios version 2.5 Acer F690GVM Bios: Phoenix Technologies,...


The AHCI can be enabled from using the correct driver but you should have enabled it PRIOR to the OS install

Acer did not always do this but often relied on compatibility mode

The speed increase is often not that much.

The BIOS on that board can be updated but you may find that AHCI still does not work as you expect.

Can't find updated ACPI Bios for toshiba satellite m45 s331. If found how to install? Getting blue screen Bios in this system not fully ACPI compliant.


I already explained in the other post ..The action required is either install a 3rd party raid and ahci driver ..and if you do not have the possibility ..just c\go to bios and enable the hard disk bus to work as ide..(disable ahci mode) I'm not sure how it will appear ..but you have to look under the bus mode..where the hard disk is seen ..It will appear as ahci enabled..and need to be disabled or ..will have raid mode enabled..and need to set it as native ..or ide compatible

I have toshiba satellite L505-S5990 model.i have installed windows xp by changing the settings in Bios that is sata hard disk enabled as compatable mode from AHCI.if i change to AHCI i can't install...


If you would like to make use of the SATA controller's AHCI features, you should enable this BIOS feature. But please note that enabling this feature requires you to load the SATA controller driver during the Windows XP installation routine.
If you do not intend to use the AHCI features, it's recommended that you disable this BIOS feature. This allows you to use the native Windows XP driver. You won't need to load the SATA controller driver during the Windows XP installation routine.

If AHCI is not enabled by the motherboard and chipset, SATA controllers typically operate in "IDE emulation" mode which does not allow features of devices to be accessed if the ATA/IDE standard does not support them. Windows device drivers that are labeled as SATA are usually running in IDE emulation mode unless they explicitly state that they are AHCI. While the drivers included with Windows XP do not support AHCI, AHCI has been implemented by proprietary device drivers.[1] Windows Vista[2] and Linux with kernel version 2.6.19 onward[3] have native support for AHCI.

Windows XP boots endless if SATA is set to AHCI


this is'nt so easy here an example solution:

Enabling SATA mode to AHCI after XP Install (applicable to most laptops, or systems) If you want to enable SATA mode as AHCI after installing Windows XP, then read on. It's a bit of a long read because of step-by-step instructions, but worth it.

I did this on on Acer Aspire 5315-2153, it seems like the basic strategy should work on other laptops or systems.

For whatever reason, you may have installed Windows XP on your new laptops with SATA Native Mode disabled in the BIOS. Once XP is installed, enabling it in the BIOS will result in a BSOD upon loading Windows because XP doesn't have the correct drivers.

I read that enabling SATA native mode will give you a slight performance inrease and slightly increased battery life, so it seems worthwhile to me smile.gif

Here's how I did it on a Acer Aspire 5315-2153 running Windows XP (32 Bit version):

- Download the Intel Matrix Storage Manager software from Intel (I think it's iata_enu.exe)or AHCI_Intel_v7.5.0.1017_XP.zip from Acer web site.

- Extract files from AHCI_Intel_v7.5.0.1017_XP.zip to e.g. C:\AHCI_Intel_v7_5_0_1017_XP files need: (you may delete the rest)

iaahci.cat
iaahci.inf
iastor.cat
iastor.inf
iastor.sys
TXTSSETUP.OEM

- Now go to Device Manager, under IDE ATA/ATAPI controllers you should

see: Intel 82801HEM/HBM SATA AHCI Storage Controller

- Right-Click on that and select Update Driver
- Say no to connecting to Windows Update to search, hit Next
- Select Install fro a list or specific location (Advanced), hit Next
- Select "Don't search. I will choose the driver to install", hit Next
- Select Have Disk
- Browse to C:\AHCI_Intel_v7_5_0_1017_XP and highlight the iastor.inf file, hit Open
- Select OK
- Now you should have a list of controllers, for the Acer 5315-2153 choose Intel 82801HEM/HBM SATA AHCI Storage Controller, hit Next
- You'll get warned that installing the device driver is not recommended, click Yes to continue installing
- Click Finish
- Click Yes to restart your computer

When your computer boots up, you need to hit F2 to enter the BIOS. Change SATA mode to AHCI, save changes and exit.

After you log into Windows, your computer will find the "new" hardware. Wait until you get the popup message to restart your computer, say Yes to restart one last time.

You may download also from Intel the RAID/AHCI Software - Intel® Matrix Storage Manager (iata70_enu.exe 5640KB) and install it in your system, it may fix in case you got the wrong Intel 82801 AHCI controller.

I give credit to Jamie Rybarczyk at HP Business Support Center forum for doing most of typing.
