Another mtrr - BIOS-e820 mismatch

[Catalin BOIE]

Hello!

Yesterday I read about a mtrr - BIOS-e820 mismatch.
So I check on a server and I think I find a mismatch:
2048MB - 1 = 7FFFFFFF, but at 0x7ff80000 there is 512 uncacheable memory.
Am I right?

Thanks!

It's a Intel MB, with 2 Pentium 4, with HT, 2GB RAM.
(Sorry I could not get more info.)

reg00: base=0x00000000 (   0MB), size=2048MB: write-back, count=1
reg01: base=0x7ff80000 (2047MB), size= 512KB: uncachable, count=1
