Indeed! Well, here's my report, shall we begin with the bad news...?

- Your MTRRLFBE doesn't work on my AMD K7 CPU / SiS chipset system :-(
It reports about found VESA 3.0, outputs the LFB address, then tells it failed to set the MTRRs. The diagnostic is not precise enough in the absence of source code or adequate app documentation :
Are you deliberately not setting the MTRRs because, maybe, your program doesn't "know" they are present and Intel-compatible ? Or did "something" unexpected happen while trying to set the regs ? Just trying to guess...
I've been running Mtrrlfbe under HDPMI32 in case it matters.

- Your port of the MuPDF is working great out of the box ! That's the *good* (TM) news Very high image quality - and I didn't have any "tweaking" to do.

Cheers...
