just tested with my NM27 IA32 package, some DLLs has CX8 so it can't run on 486: D3DCompiler_43.dll :: 100ac750: 0f c7 0a cmpxchg8b (%edx) mozjs.dll :: 1026832e: f0 0f c7 0e lock cmpxchg8b (%esi) 10268367: f0 0f c7 0e lock cmpxchg8b (%esi) msvcr120.dll :: 10075087: f0 0f c7 0f lock cmpxchg8b (%edi) vcomp120.dll :: 10007483: f0 0f c7 0e lock cmpxchg8b (%esi) 10007631: f0 0f c7 0e lock cmpxchg8b (%esi) 1000a60f: f0 0f c7 0f lock cmpxchg8b (%edi) 1000a674: f0 0f c7 0f lock cmpxchg8b (%edi) 1000a6e2: f0 0f c7 0f lock cmpxchg8b (%edi) 1000a75c: f0 0f c7 0f lock cmpxchg8b (%edi) 1000a7d6: f0 0f c7 0f lock cmpxchg8b (%edi) 1000a847: f0 0f c7 0f lock cmpxchg8b (%edi) 1000a8ac: f0 0f c7 0f lock cmpxchg8b (%edi) 1000a911: f0 0f c7 0f lock cmpxchg8b (%edi) 1000a97e: f0 0f c7 0f lock cmpxchg8b (%edi) 1000a9f2: f0 0f c7 0f lock cmpxchg8b (%edi) 1000aa66: f0 0f c7 0f lock cmpxchg8b (%edi) 1000ac31: f0 0f c7 0f lock cmpxchg8b (%edi) 1000aca7: f0 0f c7 0f lock cmpxchg8b (%edi) 1000ad1d: f0 0f c7 0f lock cmpxchg8b (%edi) 1000ad93: f0 0f c7 0f lock cmpxchg8b (%edi) xul.dll :: 10230f1e: f0 0f c7 0e lock cmpxchg8b (%esi) 10230f57: f0 0f c7 0e lock cmpxchg8b (%esi) 10230f87: f0 0f c7 0e lock cmpxchg8b (%esi)

the tool can be placed in anywhere without space. and you can change the for loop adding "/r" for recursive.

instead, I have a toolset to search certain x86 instruction(s) by using objdump and gawk: https://rthost.win/tmp/asm-cx8check.7z usage: - CD to target dir - RUN: `for %i in (*.exe;*.dll) do @path-to-batch-folder\asm-cx8check.bat "%~i"` (without " ` " mark) it will print a list, and print opcodes if found: comsvcs.dll :: 7575212f: f0 0f c7 0e lock cmpxchg8b (%esi) comuid.dll :: concrt140.dll :: 1001f566: f0 0f c7 0f lock cmpxchg8b (%edi) confmsp.dll :: console.dll :: mfc100u.dll :: 788a46a0: 0f c7 0c 00 cmpxchg8b (%eax,%eax,1)

if you have a larger disk image, you can use standard IO.SYS from Win98 or ME. LZ-DOS is actually just a apack-compressed MS-DOS 7.1 IO.SYS. and yeah, Win3.1 works when EMM386.EXE is loaded. but since there is no space left in the disk, I just can't use EMM386.EXE as it is too large for it. EDIT: tried other EMM managers within size in QEMU 0.15.1, but no positive result: - RM386.EXE: freezes - QEMM 5.11: kills XMS Manager and no XMS available after loading QEMM386.SYS, even with NOXMS specified - EMM386.SYS from Win3.0a: It can't find a place for EMS frame, and there is no NOEMS - EMM386.EXE 4.10-4.40: once loaded kills DPMI providers EDIT2: also tried to trim MS/IBM EMM386.EXE to remove loadhi.vxd at the end of file, and fix EXE header to make EXE Packers working, but packed EMM386.EXE just doesn't work. (trimmed only EMM386.EXE works, but still bigger than the free space on disk) EDIT3: tried using diet 1.45f to compress EMM386.EXE and it works.

I tried to create a 1.44MB version of my mini Win3.1 CHT version with MSDOS8 (i.e. decompressed, rlpar-w3x-patched, trimmed, apack-recompressed Q311561 EBD IO.SYS) If I replace MSDOS8 IO.SYS with LZ-DOS 7.1 and replace IO8EMMOK.SYS with XMGR.SYS (for providing XMS), it works. a test FD image is here: https://rthost.win/tmp/msd8-cwin31.7z

upstream has a thread about this: https://forum.palemoon.org/viewtopic.php?f=3&t=30950 BTW there is no need to PM me, just post it here.

I tried with Windows 3.1 Chinese Edition, and it backs to DOS prompt after showing slash screen, tried to patch win386.exe but still getting same result. loading IFSHLP.SYS makes it stalls in slash screen.

yeah thats how I hacked win2000 boot screen: https://www.betaarchive.com/forum/viewtopic.php?p=432529#p432529

2000 RTM's ntdll.dll has same thing, maybe there is another way in 2000 to not using them? EDIT: yes, it checks processor features in shared data first, it processor has no CX8 support, kernel will just skip this part.

Notice: upstream's #2490 will not be included in next build as it is too late to be merged. hopefully it will be in next-next build.

it may not work and cause #UD on new processors. https://jeffpar.github.io/kbarchive/kb/076/Q76727/

unfortunately you can't emulate a `lock cmpxchg8b` correctly. xen emulator tried to do this by using a global lock to ensure instruction emulator is the only one to modify memory/registers.

it can be more fun if patching NT setup binaries and ntoskrnl files on disc, and installing from it.

He's talking about body temperature!

using official zlib shouldn't hurt. (using google's zlib can be faster anyway)

BTW emulation may only work in UP kernel. for MP kernel, you'll need to acquire a spinlock in the beginning and release it in the end.

which version? the listing I post above is Win2000 RTM (5.0.2195.1), which may not suit XP's usage.

yeah it does. if you search `cpuid` in ntoskrnl.exe 5.0.2195.1, you can find one in `sub_553EB4`: INIT:0055415C mov eax, 1 INIT:00554161 cpuid INIT:00554163 test edx, 100h INIT:00554169 jz short loc_554177 INIT:0055416B or ds:dword_47DEEC, 80h INIT:00554175 jmp short loc_5541EA INIT:00554177 ; --------------------------------------------------------------------------- INIT:00554177 INIT:00554177 loc_554177: ; CODE XREF: sub_553EB4+29Ej INIT:00554177 ; sub_553EB4+2B5j INIT:00554177 lea eax, ExInterlockedCompareExchange64 INIT:0055417D lea ecx, sub_40078C INIT:00554183 mov byte ptr [eax], 0E9h INIT:00554186 lea edx, [eax+5] INIT:00554189 sub ecx, edx INIT:0055418B mov [eax+1], ecx INIT:0055418E lea eax, ExInterlockedPopEntrySList INIT:00554194 lea ecx, loc_4006F0 INIT:0055419A mov byte ptr [eax], 0E9h INIT:0055419D lea edx, [eax+5] INIT:005541A0 sub ecx, edx INIT:005541A2 mov [eax+1], ecx INIT:005541A5 lea eax, ExInterlockedPushEntrySList INIT:005541AB lea ecx, loc_400704 INIT:005541B1 mov byte ptr [eax], 0E9h INIT:005541B4 lea edx, [eax+5] INIT:005541B7 sub ecx, edx INIT:005541B9 mov [eax+1], ecx INIT:005541BC lea eax, ExInterlockedFlushSList INIT:005541C2 lea ecx, loc_400714 INIT:005541C8 mov byte ptr [eax], 0E9h INIT:005541CB lea edx, [eax+5] INIT:005541CE sub ecx, edx INIT:005541D0 mov [eax+1], ecx INIT:005541D3 lea eax, sub_402352 INIT:005541D9 lea ecx, ExInterlockedAddLargeInteger INIT:005541DF mov byte ptr [eax], 0E9h INIT:005541E2 lea edx, [eax+5] INIT:005541E5 sub ecx, edx INIT:005541E7 mov [eax+1], ecx and 2nd `lea` is the `cmpxchg8b`-less version of upper one.
