Downgrading Acer Aspire X1800 to Windows XP

Hello Experts,

I have an Acer Aspire X1800 that came with Windows 7 that I need to downgrade to Windows XP.  I already checked on and XP drivers are available.

To downgrade, I just plan to boot the PC with the XP CD and format.

Does anyone see a problem with this as 2 years ago, I had another acer (can't remember the model) and I blew the motherboard somehow.  At that point I  didnt check if Acer had XP Drivers for that model.

If the drivers are available it should be pretty easy.

So, just boot with the XP CD and format?

why do you downgrade?
APD TorontoSoftware DeveloperAuthor Commented:
OK, as acl-puzz verified with my plan, I booted with my XP CD, got my blue Windows Setup screen and the PC stops installing when the message "Setup is starting Windows".
When I try turning off the PC, I get:
A problem has been detected and Window has been shut down to prevent damage to your computer.
If this is the first time you've seen this stop error screen, restart your computer. If this screen appears again, follow these steps:
Check to make sure any new hardware or sofrware is properly installed. If this is new installation, ask your hardware or sofrware manufacturer for any windows updates you might need.
If problem continue, disable or remove any newly installed hardware or software. Disable BIOS memory options such as caching or shadowing. If you need to use Safe Mode to remove or disable components, restart your computer, press F8 to select Advanced startup options, and select Safe Mode.

Any help would be greatly appreciated.

Check the BIOS for SATA settings. Change them to Compatable (might be called something else) mode. Then try installing again.

OK, as acl-puzz suggested, I went to the related EE question, and the accepted answer was to add SP2 to a new XP CD AT
I went trough most steps, skipping the RAID ./ SATA driver steps as they were optional, and I do not know where to get them?  By the way, in CMOS, i changed the Onboard SATA mode from AHCI to Native IDE (if that answers edbedb's question?)
On the last step, being burning the SP2 Win Setup using Nero, I used Roxio instead.  However, as Roxio did not have all the option mentionned, such as selecting the emmulation type, i also skipped these options.  As a result, when I boot from my newly created bootable CD I get
CDBOOT: Cannot boot from CD - Code: 4
NTLDR is missing (this may be related from my second attempt below).
Finally, I downloaded Nero Multimedia Suite 10 - trial version (which includes Burn ROM), but at installation I crash at the C++ Distribution Installation.
For the above, I had been using a XP Home CD.
As for my second attempt, by reading this article I realized that I needed to upgrade my Win Installation CD to include SP2.  I do have another premade Win XP PRO SP2 CD, which booted correctly, passed the acpi.sys error, and allowed me derlete all my partitions and format.  When it started to copy files, I kept getting corrupt file: cinemst2.sys, cpgdap01.sys, cyycoins.chm, and ten more files before I aborted setup.
My XP PRO CD isn't bad, and I also remember from my older computer that I'm now trying to replace with the Acer, and the computer before that, I was running into the same file curroption problem, and my solution was to format and Install Home, then upgrade to Pro, but now from above, I can't get Home going.
Any suggestions?
adding service packs into operating system called slipstreaming process here is an easy way of doing this with nlite utility see the Visual guide below there
"i changed the Onboard SATA mode from AHCI to Native IDE (if that answers edbedb's question?)"
Yes that is what I wanted you to do. Now you can use any Windows installation CD without doing any slipstreaming.
" I can't get Home going."
What is happening when you try?

After I my onboard SATA mode, I tried my original XP Home CD (SP1), and I got the situation/error described above in 04/27/10 09:30 AM, ID: 32275134
What do you think?
And the SATA mode is set to IDE? Are you sure?
The computer was starting Windows before?
APD TorontoSoftware DeveloperAuthor Commented:
yes Windows 7
Does your other XP installation CD get pass that?

My Home SP1 CD crashes before formatting
My XPP PRO SP2 goes beyond formatting, but when copying the files, i get corrupt files message.
As mentioned, my XP Pro isnt corrupt, but before I was able to workarround this by installing Home first, then uppgrading.
Then it sounds like you either have a weak cd drive or damaged cds. Try making a copy of the installation cd and using it.

Question - when I copy the installation cd, do I need to specify it as bootable, can i just copy it to my HD then copy it to a new CD, using just the Win XP Burn Wizard?
I also have a 2GB flash drive, that I can try to copy the CD files and boot off, but same question, do I need to make it bootable first, and how?
Those are good questions but I don't know the answer off hand. I always use Nero or NTI to duplicate CDs and I never had much luck creating bootable flash drives.
i think you did not see another solutions tehre regarding ACPI error in the above Experts-exchange link i gave you there are couple good possiblities else then service pack

anyways did you try this link method of integrating sp2 into XP?It works!

DONE!  The slipstreaming helped, plus I had bad CDs
