Dear forum members, although this may be a bit long, after a week or so of torturous research I believe I have reached a simple solution to a number of frustrating problems. My computer has an Abit AN8-V motherboard running an AMD Athlon 64 Processor 3000+ at 1.81 GHz with Windows XP Professional & Service Pack 3.

My problems started when I decided to update my hard drive to a 32 meg cache WD 10EADS 1TB drive. It wouldn’t boot most of the time and would sometimes produce the “blue screen of death” reporting “MACHINE_CHECK_EXCEPTION” with a code of “0x0000009c”. After a lot of arguing with the drive retailer, they agreed to replace the drive which resulted in much the same problems.

I then went and purchased a 32 meg cache 500GB Seagate Barracuda 7200.11 ST3500320A drive which resulted in a no boot situation much the same as the WD10EADS. If I opened ntbtlog.txt it would report the following on both drives:

Did not load driver ACPI Uniprocessor PC

Once it didn’t load driver ACPI Uniprocessor PC, it then wouldn’t load most of the other 100+ drivers and would halt the boot process. The only way I could get it to boot was to boot in safe mode, shut down the computer and then boot in normal windows mode, or sometimes using the last known good boot.

After a tremendous amount of searching and reading on forums, Microsoft and other web sites, I went back to AMD’s web site http://support.amd.com/us/Search/results.aspx?k=Athlon and downloaded a 5k file http://support.amd.com/us/Processor_TechDownloads/largePageMinimum2.zip. This file unzips to largePageMinimum.reg which adds the following line to the registry:
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Session Manager\Memory Management]
"LargePageMinimum"=dword:ffffffff

Since adding this line to the registry, the hard drive boots first time every time and hasn’t given a problem since. I don’t know if it will help in all cases of large hard drives not booting in Windows XP but it is only a 5 minute add to the registry, if it doesn’t work on your machine, it is easily enough deleted. I hope this helps some other poor lost sole.
