You need to be aware, that the checksum verification of both loader and kernel is disabled when the patch is active. PatchPae works like a charm, no issues so far, using current Intel HD drivers. Still it has at least 2 years of future, until Microsoft ceases to support Windows 7. My laptop is 8 years old HP 6730b, very solid, supports 圆4 and PAE ( Physical Address Extension), but will not run Windows 10 without ugly graphic driver issues. I built it with Visual Studio 2017 Community Edition along with the great Process Hacker. I took inspiration and revision check from Elbandi. text:004295FF mov eax, => patch to xor eax, eax nop nop The offsets may change, but it is probably easier to maintain, as the error code C0000428h should stay constant.text:004295F7 loc_4295F7: CODE XREF: ImgpValidateImageHash(x,x,x,x,x)+EFj The original patch was for ImgpLoadPEImage, but I decided it would be more robust to patch the end of ImgpValidateImageHash. Apparently it has changed in revision 23569.
I looked into wj32's code and disassembled my winload.exe. However, the patch of my current Windows 7 SP1 winload.exe version. Recently I came across an interesting article by Raymond.CC "Make Windows 7, 8 and Vista 32-bit (x86) Support More Than 4GB Memory" and PatchPae2 by Wen Jia Liu aka wj32, which should enable PAE up to 128 GB for all current 32-bit Windows versions. I have this old Win7 32-bit laptop with 4 GB of RAM, but it was only able to use about 2.9 GB, the rest was "reserved for hardware".
