Direct memory access controller driver problem ?

Thanks for your reply, but it appears you didn't quite read all my post ... I
DO have a standalone video card installed, the graphics are NOT run 'on
board'. My graphics card is configured for 64Mb RAM - SELF CONTAINED - PLUS
the 512 Mb system RAM installed. My question was mainly revolving around why
my system tells me two distinctly different things - that being, on the one
hand, it says there is NO driver installed for the DMA controller, yet it
ALSO says that there IS a "current" driver, as described in my post. I am
concerned that there appears to be a mere 8Mb of RAM 'running' the machine,
as there is this "lost" 8Mb that I cannot account for ?! According to the
system properties window, I only have 504Mb installed RAM - but there are 2 x
256 Mb chips = 512Mb - so where is the other 8Mb going ?? I am reasonably
convinced that the machine, for some reason I cannot fathom, is using THAT
8Mb to run the graphics, yet everything I can see points to the graphics card
being active, and set at 64Mb ? It just is NOT running that way ... This
machine originally had 32Mb ON BOARD Intel graphics, but that IS disabled -
both via BIOS and via device manager - yet there's no way the quality I have
now comes from a dedicated 64Mb graphics card - even though it assures me it
IS fully functional and the other Intel chip IS disabled.
With regard to the DMA controller, I honestly do not know anything about it,
so I am therefore presuming that it must be a reasonably critical device and
thus needs to work correctly, but how CAN it be working - at all - if it has
no driver ? Even though it says it DOES elsewhere ! Surely no matter WHAT
graphics card(s) I have, if it/they cannot access the available memory, then
surely they cannot operate correctly - and I am presuming that this is the
FUNCTION of the DMA controller - to let the right thing have the right memory
as and when it wants it ?! Am I wrong in that assumption ? Obviously, I'm no
expert, but surely if the DMA controller is not permitting whichever graphics
card is current to HAVE access to the memory it requires, then there are
going to be these nasty problems, no ? I am utterly confused now ...
Even I realise that what I've just said makes little sense - because if the
graphics card has its OWN RAM, then why would it need access to the SYSTEM
RAM ?!! So what IS going on here then ? Thanks again for your help, but
unfortunately I'm not sure what to do with your suggestions, they don't seem
appropriate to what problem I seem to have Sorry.

Hello,

I am getting exactly the same problem re the direct memory access, it says
no driver is installed, but on the other hand says it is working normally!!

I discovered this when running a DVD creation program, which says that the
DMA controller is turned off. When updating the driver, it could not find a
better one than that already installed.

Not sure if the failure of the windows updating software to download updates
has any relation to this.

Any help would be much appreciated....

I am getting exactly the same problem re the direct memory access, it says
no driver is installed, but on the other hand says it is working normally!!

I discovered this when running a DVD creation program, which says that the
DMA controller is turned off. When updating the driver, it could not find a
better one than that already installed.

Not sure if the failure of the windows updating software to download updates
has any relation to this.

Any help would be much appreciated....
