1 Hi,

3 (Sorry if this is off-topic but I really don't know where to turn to...)

5 Anyone with experience/knowledge about MTRR/PAT and who can tell me
6 where to find information about these things so that I might see if
7 there's a problem or not? I've tried google but in this case they're not
8 my friend... :-(

10 The MTRR of one of my machines look like this:
11 reg00: base=0x00000000 ( 0MB), size=2048MB: write-back, count=1
12 reg01: base=0x80000000 (2048MB), size=1024MB: write-back, count=1
13 reg02: base=0xbff00000 (3071MB), size= 1MB: uncachable, count=1
14 reg03: base=0x100000000 (4096MB), size=1024MB: write-back, count=1

16 The gfx card is a (pcie) Radeon HD3850 and the base address for the
17 framebuffer is 0xd0000000 (64-bit, prefetchable) [size=256M]. It also
18 has (what I believe is) registers at 0xf1000000 (64-bit,
19 non-prefetchable) [size=64K].

21 One of my other machines get's warnings about
22
23 All the relevant info that comes up when I use google relates to AGP but
24 I use PCIE, so is it still relevant? Also, are there other devices
25 besides the graphics card that would benefit from having a correct MTRR
26 setting?

28 TIA,
