it doesn't seem to have a built-in vga. my only graphics card is a radeon
r300.

nforce2 unknown memory device

[Rahul Karnik]

Gregor,

I also have an NForce 2 based board on which I have successfully used both
1GB of memory and an AGP video card (Radeon 9000). The unknown memory
controllers do not seem to affect anything. Are you sure you have loaded
the AGP modules (both agpgart and nvidia-agp)? As for all the memory not
being detected, some memory is being reserved for kernel use -- how are
you coming up with the numbers you sent?

Thanks,
Rahul

Some chipsets with built-in VGA reserve a certain amount of system
memory for graphics memory.

No idea.

nforce2 unknown memory device

[Gregor Burger]

hi

linux is not able to detect all the memory installed on my mainboard.
my kernel is 2.4.22 but i tried 2.4.23pre2, 2.6.0-test3-6[mm3].
i tried with 4gb and without. 

lspci schows:
00:00.0 Host bridge: nVidia Corporation: Unknown device 01e0 (rev c1)
00:00.1 RAM memory: nVidia Corporation: Unknown device 01eb (rev c1)

00:09.0 IDE interface: nVidia Corporation nForce2 IDE (rev a2)
00:1e.0 PCI bridge: nVidia Corporation nForce2 AGP (rev c1)

i tried to switch the memory sticks but nothing. when i install 1024 MB 
ram linux detects 1008; with 512 i get 502.

the xserver can't init agp with the error xf86_ENOMEM; but i think this
is a couse of the missing memory that is not detected.

is that a problem of my hardware (defect) or are the nforce2 chipsets
not yet fully supported?

thanks for your help.
