Can not install Windows7 ! firmware (bios) is not ACPI compatible

Guess your computer is not compatible with Windows 7. Reinstall windows XP run compatibility test from Microsoft

im sorry there is no one answer to this problem a couple of possible solutions are to 1. Reboot the computer to restart Setup.
2. When Setup starts again, press F7 when you see the "Press F6 if you need to install a third-party SCSI or RAID driver" screen.
Windows automatically disables the installation of the ACPI HAL and installs the Standard PC HAL. You should also contact the manufacturer of your computer to obtain a BIOS that is fully ACPI compliant.

you could have a bad stick or sticks of ram


or you need to flash/update you bios


or you need to clear the cmos [removal of battery or a jumper switch depending on your mobo]

once again im sorry to not have a clear one size fits all solution to this problem i hope this helps you and please vote for me

please change the cbos battrey and set the bios optimize default
F10>yes.


hope it will help tou
dont forgate to vote me

It's possible that the BIOS setup has been accidentally set to non ACPI mode. Check in the setup to ensure ACPI is enabled.

Other possible causes that have been - memory expansion, overclocking and incompatible driver software. Check out what you have recently installed or updated on your computer.

my client office one system working windows , when booting time displaying blue screen error" acpi.sys " . and then continusly system restart., but, i was maked the first and second repair, still now i didn't got solution for this problem. please help me. and also i want need ur help for blue screeen error.

Please contact your system vendor for an updated bios. If you are unable to obtain an updated bios or the latest bios supplied by your vendor is not ACPI compliant, you can turn off ACPI mode during text mode setup. To do this, simply press the F7 key when you are prompted to install storage drivers. The system will not notify you that the F7 key was pressed - it will silently disable ACPI and allow you to continue your installation."

RESOLUTION
Manually install the Standard PC hardware abstraction layer (HAL):
1. Reboot the computer to restart Setup.
2. When Setup starts again, press F7 when you see the "Press F6 if you need to install a third-party SCSI or RAID driver" screen.
Windows automatically disables the installation of the ACPI HAL and installs the Standard PC HAL. You should also contact the manufacturer of your computer to obtain a BIOS that is fully ACPI compliant

I have seen on many forums that ACPI makes a lot of troubles to a lot of users under Windows. I will try to explain several things about ACPI and I hope that you will be able to solve your problems after you read this article. I cover only most encountered issues, but always there is a choice even if it's called ACPI disable.:)
The computer ACPI support is detected in the setup stage, but there are less frequent cases when ACPI is not detected and the Standard PC HAL is installed. If you want to force the installation of the ACPI HAL:
1. At the blue screen of the Windows XP setup when it prompts you to press F6 for additional mass storage devices press F5 and you will have a list of options.
2. Choose the proper HAL for your machine remembering that there are also different HALs for multiprocessor machines.
3. Complete the setup, go to Setup / Control Panel / System / Hardware / Device Manager / Computer. If you have listed the Advanced configuration and Power Management (ACPI) the process was completed successfully.
Warning: You can do the same thing if you don't want to install ACPI and your BIOS doesn't support ACPI disable setting. Just choose the Standard Computer HAL from the list of options.
Another method to disable ACPI is:

• wait for the text-phase of XP setup to complete
• before XP Setup Wizard to load, boot into DOS and change ACPIEnable = 0 from ACPIEnable = 1 in file c:\txtsetup.sif

The reason why ACPI is not installed on a computer with known ACPI compatibility may be a Microsoft known subtle incompatibility which can lead to hardware instability. In the installation step Windows XP checks the BIOS compatibility with ACPI and the BIOS presence on a known bad list. If the BIOS is there ACPI is not installed. Of course than errors can occur so you can force the ACPI installation (not recommended).

Try disabling it in the BIOS first, this can not be done on a computer with the operating system already installed as it will cause the machine to stop. MUST be done when you initially install the OPERATING SYSTEM.

try to make bios settings default and make a proper installation

The bios in this system is not fully ACPI compliant. Please contact your system vendor for an updated bios. If you are unable to obtain an updated bios or the latest bios supplied by your vendor is not ACPI compliant, you can turn off ACPI mode during text mode setup.
