Hello! I tried installing the "WinXP-PAE-Patch" and while it appeared to work, it causes my machine to BSOD with "IRQL_NOT_LESS_OR_EQUAL" after opening a few programs. I have run Memtest86+ and it passed 2 passes with 0 errors, plus Windows 10 ran fine, albeit slowly, on this machine. The problem I have is, without the PAE patch, Windows XP is only able to use 2.5GB of the 4GB RAM. Whereas the PAE Patch let me use all 3.75GB (as I have allocated 256MB to the X1200 in the BIOS). Is there a way of uninstalling this patch? There is no documentation for this and I can't find the supposed backup. I did try another PAE patch before this, and that kept causing a black screen instead of a BSOD. Thanks!
I never had problems with PAE in XP, even on machines with Intel iGPUs that have problems in Vista-W10 x86 Anyway a good patcher usually duplicates the boot entry to boot with or w/o the PAE patch, just set the option you want as the default one.
Hi, you can just change back to the original one ntoskrnl.exe and/or ntkrnlpa.exe in windows\system32 Dietmar
No need to "change" anything, unless the patch was poorly implemented All you need is to set the right order (or remove the unwanted option) in boot.ini Just like the sample below Code: [Boot Loader] Timeout=5 default=multi(0)disk(0)rdisk(0)partition(1)\windows [Operating Systems] multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Windows XP Media Center Edition 2019 PAE" /fastdetect /pae /noexecute=optin /kernel=ntkrnlpa.exe /hal=halmacpi.dll multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Windows XP Media Center Edition 2019" /noexecute=optin /fastdetect
