Acer AXC-603 Install Windows 7

I had been searching for ages trying to fix BIOS is not ACI Compliant issue with a Acer AXC-603 computer we bought for work.

I eventually found an amazing post on eightforums.com and i thought i would share the instructions here as well

STEP 1 – Downgrade BIOS/UEFI
WARNING: DO THIS STEP AT YOUR OWN RISK. IF SOMETHING GOES WRONG HERE, YOU RISK PERMANENTLY DAMAGING YOUR COMPUTER. I MODIFIED THE BATCH FILES TO IGNORE CHECKING ROM ID. IT WORKED PERFECTLY FOR ME BUT THERE ARE NO GUARANTEES THAT IT WILL WORK FOR YOU. I AM IN NO WAY RESPONSIBLE IF THE FOLLOWING INSTRUCTIONS DAMAGE YOUR COMPUTER.
This step depends on what operating system you currently have on the machine. You will need the files provided HERE (Please download a local copy. I will try to keep this available as long as i can but cant make any promises for the distant future)

Step1-A – IF NO operating system
If you have a recovery disk you can also try using it or the recovery partition (Alt+F10 at boot). If that doesn’t work, the easiest way to do this is to download the evaluation copy of windows 8 from Microsoft and do a fresh installation.
After windows 8 is installed follow steps from Step1-B.

Step1-B – IF YOU ARE IN WINDOWS 8
Open the “Bios WIN” folder from the files provided HERE. Navigate to the “WIN” directory. Right click on Flash.bat and run as administrator (can also be run from an elevated command prompt from within windows)
You should see a command prompt popup and it will now downgrade your BIOS.
If you manage to get through this step, you’ve won 90% of the battle so cheer UP!

Step1-C – IF YOU ARE IN DOS / FREEDOS
I haven’t tried this personally but the following should theoretically work
Use another machine to download the provided files. Burn them on a CD/DVD that is accessible from dos.
Boot to dos and use the “cd” command to navigate to the “Bios Dos” directory
Execute Flash.bat
If you manage to get through this step, you’ve won 90% of the battle so cheer UP!

STEP 2 – BIOS/UEFI Settings
After flashing the bios press “Del” while booting to make sure the following settings are set
Set secure boot to disabled
Set CSM mode to always
Boot Priority – As per your preference.

Step 3 – Install WIN 7
Boot from windows 7 DVD or USB to install windows 7. I personally used a DVD to complete the process so I can verify that is working.
Hard disk Partitions – If you have left over partitions from previous installations, delete all of them and creating new partitions. You can try installing over the old partitions but I personally haven’t tested this.

Step 4 – Install Drivers
Install the drivers provided in the link

STEP 5 – ENJOY WINDOWS 7
