 I tried memtest86+ 2.01 (for about 3 hours) and it didn't display any
errors. I use f9 x86 but I have 4GB of memory. fedora sees only 2,25gb
but I thought it should be about 3gb. where are the rest 0,75gb? Could
this be connected with this?

Actually winxp sp3 sees also 2,25 gb but I see 4096mb in the bios
settings. maybe bios/dsdt table problem or sothing else?
