The BIOS in this system is not fully ACPI compliant



The ACPI Bios in this system is not fully compliant to the specification. Please read the readme.txt for possible workarounds, or contact your system vendor for an updated bios.

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. 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." 
This behavior can occur if Windows has detected that the BIOS in the computer is not fully Advanced Configuration and Power Interface (ACPI) compliant. 

This is a very delicate problem and it will cause a little headache especially if you are a newbie in working with a pc. In the following I will present you two of the solutions to this problem .



1 - This method can be done in 2 ways.

Safest way to do it ? You will need a bootable Windows XP sp2/sp3 cd. You can find and download free Windows XP almost everywhere on the internet. (if you cant find it just leave a comment and i will provide you a free link). Burn the image on a CD, I recommend to use gBurner is the most simple to use CD/DVD burner on the net. After that: 
-- Reboot the computer to boot cd. If cd doesn`t boot automatically you will need to enter in BIOS Setup - Boot - Boot device Priority, and select cd/dvd unit, save settings and pc will restart. If cd still doesn`t boot when you restart pc press one of the keys  F8 / F11 / F12 to activate boot menu, select cd/dvd unit and hit enter. 

Windows will ask you to press any key to boot from cd, press Enter again and be ready because immediately a blue screen will appear and bellow a message "Press F6 if you need to install a third-party SCSI or RAID driver". When you see that message press F7 fast. Is very important to press when you see the message "Press F6 if you need to install a third-party SCSI or RAID driver" because if you press later, setup will not recognize F7 command anymore. 
Windows automatically disables the installation of the ACPI HAL and installs the Standard PC HAL. 

Second way to do this is to Manually install the Standard PC hardware abstraction layer (HAL). To prevent Windows XP from automatically determining the system HAL during the upgrade or the installation of Windows XP, you can manually force in a system HAL. To force in a system Hardware Abstraction Layer (HAL) during an upgrade or installation of Windows XP:  
During the Text-mode phase of the Setup program, when you receive the following message "Press F6 if you have to install a third-party SCSI or RAID driver." across the bottom of the screen, press F5. 
The screen displays only two computer types at a time. To scroll up or down to view the complete list, use the arrow keys.




  2 - This method require some attention. 

If you already tried method no1 and your pc still display that error or another error you will need to verify your pc components. Often error "The BIOS in this system is not fully ACPI compliant" can be cause by your Hard Disk or your RAM memory. What you can do about ? 
First, if you have 2 or more Ram memory replace by turn one of them and restart your pc. If error still appear replace your hard disk and try install on the new hard drive your favourite operating system. 


Generally, BIOS doesn`t need update because bios systems are build to work many years and the error might be caused by another malfunction of your pc. In this article i presented only 3 of them.

    2. Some individuals had receive the same error when on of their ram bars stopped to work or they tried to upgrade their ram. From what i see you are experiencing the second cause. That`s i said the second method require attention. If your computer doesn`t receive this error with the old ram and is doing this with the new ram means your ram bars are not compatible with other system hardware or they are broke. Try to install a fresh new copy of windows and follow the first step from this article to see if this malfunction is coming from your ram or is just a complicated software issue and can be solved very simple. Good luck and come back to let me know what you succed. :)

  37. Hello , if anyone still having this problem and nothing helped , here is my solution.

    In the bios, if you have dvd rom as the first boot device or the usb drive, set your hard drive as the first boot device and dvd as the second and so on, this solved it for me,really.
