The BIOS menu , you can set that anywhy you want.
OP never once, told.
1: how many drives (HDD;/SSD ) present
2: if running factory mobo raid , as you sure can.
3: or if 1 drive and wanting AHCI or not. or IDE. its your choice.
4: if any of the 6 other PCI slots have RAID card present. or other cards beside the HP top slot video card.

lacking whats in your box and your intents, the answers are impossible.. to vague questions.
a: what do you have now.?
b; where do you want to go... (Bill Gates like)
hark !

    First the good news, unless you had multiple drives in a RAID configuration, that message is normal. How long are you leaving it?

    My advice is to turn it off at the mains for a bit, then turn on and leave it for 30min all by itself, it is possible that windows needs to to sort itself out. If after that time it is still dead, insert the windows CD and re-start the machine.

    Boot from the CD, F12 at power up should get you the boot options and then let windows do a repair. If you have the option, opt for a restore point a couple of days back. If all else fails and it still does not work, opt for a windows re-install

    nobody said the dead word.. 4 years ago.
    but in fact boot issues are common,here.
    if BIOS is reset, it will not boot to hdd.
    no HDD stated, no windows version stated.
    and matters. in all cases.
    In fact AHCI does work very well. here.
    the AHCI bit is here, CLEAR as day

    see it.

    f10, bios, is the hot key at power on.

    or the whole page of facts on this ONE PC

How to change the ide mode into ahci on the bios?

If the BIOS supports it, the option is usually available in the advanced options area. Each BIOS is slightly different. Be advised, however that switching the mode from IDE to AHCI will result in Windows not booting if already installed. The two modes are not compatible. Using AHCI will result in needing to reload the OS. Also ensure that you backup all data on the disk as well to prevent data loss.

Need manual for C51GU01

In the bios there's an option to configure SATA as "IDE", "AHCI", or "RAID".
If you don't have data to loose, try this. Install the drive, set the BIOS option to "IDE", boot to windows, install manufacturer's IDE/SATA controller drivers, restart, set the BIOS option to "AHCI".

AHCI stands for Advanced Host Controller Interface. There are rumors that setting AHCI without manufacturer's drivers will give you a BSOD. I'm not sure if you can recover it by switching back to "IDE", but it should be worth a shot.
Best of luck

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.

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.

I have a laptop a205-s6812 and i want to install xp but it wont continue it say about hdd cannot detect and i know you know what i mean? and cant you help me to solve this

I can't be sure, but probably the reason is that you have a SATA disk drive and the BIOS AHCI settings are not those that XP expects.
This is a tricky workaround: enter the BIOS and flip the AHCI settings, boot in XP and see whether the disk is now recognized. Once you install XP, you need to install the appropriate disk drivers for AHCI support. BEWARE - at that point, after the next reboot, the situation will be MIRRORED: you won't be able to see the hard disk with the new drives until you flip the AHCI back! (My guess is that the current setting is for Vista and says something like "Top AHCI performance" or the like. You need something like "Good ol' slow and steady mode, non-AHCI, thanks". Once you have successfully updated XP, go back to the faster setting.

I have done this successfully on my Dell XPS 1330.

Let me know how it goes, and have a nice day!

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 from Acer web site.

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

- 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.
