WinXPPAE v3.5 RAM patch for WinXP 32-bit not work with CSMWrap on Haswell PC

[Gelip]

Today I test RAM patch WinXPPAE v3.5 on Haswell and patch not work with CSMWrap 1.2.1

After enable CSM in bios and boot PC in normal legacy mode patch works OK: https://forums.mydigitallife.net/threads/winxppae-v3-5-winxp-sp2-issue.89363/#post-1881947

P.S. On another PC, for example, Intel Gen8 patch works even with CSMWrap - this means that there is only a problem on Haswell

I tested only WinXP SP2 but on SP3 probably also problem.

Yea, with CSMWrap 1.2.1-15 WinXPPAE v3.5 patch works :-)

I tested again CSMWrap 1.2.1, 1.2.1-15 and 1.2.2 and RAM Patch v3.5

1.2.1

• winload.exe: iGPU+SeaVGABIOS or PCIe graphics card+VBIOS card = work
• ntldr: iGPU+SeaVGABIOS or PCIe graphics card+VBIOS card = not work

1.2.1-15 or 1.2.2 - all works
