DOS ain't dead

Eric Auer has updated his CPULEVEL tool (which tells extended CPUID info: e.g. family/model/stepping, processor name, MMX or SSE features, etc.), which returns an errorlevel for processor detected.

Changes: SSE3 can now be detected (and fixed SSE report duplication as well as made easier to read overall).

Know your limits.h

COOL. I get however only one "level" while RayeR's CPUID finds 4 Anyway, 3 KiB only, open source, compiles with FASM ... a serious competitor on DOS CPUID'ding market

BTW my CPUID is aimed a bit higher, not only base CPUID info but also reads CPU MSRs to get some further info about multipliers, FSB clocks, cache and core temperature. Also it's written to be portable to win32 and linux (the advantage of GCC-DJGPP). Of course if you're space limited it's beeter to use small ASM programm.

I know IIRC it was hard work to get the Ring0 working not very long time ago ... I don't neglect the usefulness of your's.

Also it remains hack MSRs under linux. Currently it rely on your /proc/blabla which may not present in older kernels. But i'm linux lama. AFAIK I would need to write my own kernel module, which is not for beginners :) or is possible to shoot through protection? :)

Seems Eric silently updated to CPULEVEL2008

What's new:

??? (kicked out the old version, COM size few bytes bigger)

Compared to the Dec. 30th version, this one can separately detect every pre-CPUID family of cpu (instead of lumping together 8086/186 and 386/486). But yeah, he should've named it CPULEVEL 2008, IMO, instead of refreshing the old version. Oh well.

NASM, actually (although you only need to make two or three minor changes).

However, as you told me a while back, you were almost exclusively only interested in Intel cpus. Tsk tsk.

I know Eric used NASM ... but compiles with FASM as well after some very minor changes, saves a few bytes, and points to several bugs of Eric

...which you, of course, already reported to him.
