[HACK] NT4 Intel SSE/SSE2 Driver for Any CPU

Post by roytam1 »

diff:
000000D8: CC 63
000000D9: F7 63
header checksum

000002CD: 03 01
000002CE: 7F 90
000002CF: 3E 90
(relax CPUID limit)

000002F5: 75 90
000002F6: 0B 90
(relax CPUID vendor string limit)

With these changes intlfxsr.sys works in every CPU including AMD and VIA C7 CPUs.

I'd use another question to answer your question: Why limiting the ways for playing your toy?
With SSE-capable CPU and SSE driver, NT4 can run programs that requires SSE instructions.

Very interesting, would this work on newer versions of NT? I have an old slot a Athlon with no sse/sse2 support so it would be cool to get it to run sse code.

If the CPU doesn't support SSE/SSE2 at all, this driver cannot make it available.

So it only allows NT4 to use SSE/SSE2 code?

Yes.
NT4 kernel rejects SSE/SSE2 instructions without this driver.

Good for the many Windows 2000 beta builds here on FTP.

Yeah, thanks for this.
Windows Defender for great justice! Bugs are an international trading company. I need to defeat the anti-debugging and obfuscation methods. It wasn't for Intel's absurd ability to load in ie6. Why even waste time with people in an envelope?
