ME to XP - BIOS not fully ACPI compliant

I have an HP with ME, version 4.9.3000, BIOS version EPP version 9.00, 511 MB Physical mem., 2 GB virtual. Halfway through XP install screen freezes saying- BIOS not fully ACPI compliant. Go to for updated BIOS or turn off ACPI mode during text mode setup - press F7 when prompted to install storage drivers. Hardware-update did me no good and the prompt to install storage drivers never came. HELP!

This issue is now well known. If you can't get a XP compliant BIOS then you need to run the old OS until you replace the motherboard.

Microsoft has NO PLANS to "workaround" this issue. And owners that manage to do so are usually crashing on a daily basis.

In closing, if you had provided the model number of the machine, I would have looked, but since you didn't, I'll tell you to look for it at

Well, this is not good news. In May, I suddenly needed to reinstall my ME OS. Since doing so things have been downhill ever since. My machine is a Dell Dimension 4100 and I have been doing the step by baby steps to convert to the XP Home Edition.
The important reason for needing to change is that my bookkeeping software will no longer accept my data files even with getting all the updates and going through the weeks of trying everything anyone could suggest. Finally the software co. said that ME will no support their later versions which I had purchased and TRIED to install. My data files are good from the backups I had done. I have checked with several other bookkeeping software companies and they say the same thing. Because the floppy drive will not work properly, I downloaded the BIOS that did not require an a drive. it says that my memory managers are aborting the process. Does any of this ring a bell?? I am curious to know how someone else with this problem is coping??
I hope it was ok to post here to get some moral support
and let you know you are definitely not the only one with this problem.
This is why my son-in-law went to a different venue for his computers and OS's

Without the error message or a story...

All I can do is note I read your post and wish you the best of luck in repairing your machine.

Also, how did this story turn from a HP machine to a Dell? Or is this a new post you tagged onto someone else's post?
