How to enable DMA

hey i was trying to enable Direct memory access
i thought u just needed to go to right click on my computer>properites>device manager>disk 
drives>then the hard drive  but i go to settings and there no thing there only a 
few options but no DMA. On a web site it said go to IDE ATA/ATAPI controllers in 
device manager but there is no IDE ATA/ATAPI controllers in device manager.
on the age of mythology readme it says this dma thing will make my computer faster 
i tried to do this a long time ago but didit bother becasue computer was going fast 
but age of mythology is quite slow lol

oh ya and under system devices in device manager theres a yellow ! next to plug and 
play bois extension and i go into it and it says : the NTKERN.VXD device loader(s) 
for this device could not load the device driver (Code 2) and says update the drivers 
but i click update and it cant find any drivers for it. i remeber it being there 
a long time before this so its not a new device i think it dont tell me what plug 
and play bois extention it is so i wouldent know where to get the drivers for it 
from

Hi Dan.

Well on my Win98SE I have a DMA checkbox on the hard drive but I never check it.

I do check the DMA checkbox on my PlexWriter CD Rom because Nero says to do that.

Why do you need to checkmark your hard drive?

Some chipsets like VIA need special drivers so the motherboard or system builder 
supplies the drivers and the configuration utility to set them up.  Unless your system 
is damaged, which it sounds like it could be, you need to go to the chipset manufacturer 
or motherboard/system builder's website for updates or the drivers for your system. 
 For VIA it is called 4 in 1 driver package updates.  When these are installed, the 
normal Windows settings options will usually disappear as you must now use their 
config utility to set the DMA and do other tasks for maintenance.  Unless your system 
builder or motherboard manufacturer has the required files or has included them with 
your system, and the associated utility for enabling the DMA settings, you could 
be out of luck if WIndows won't specifically handle your hardware correctly. You 
may find them on hosting sites also, at the risk of downloading an infection also 
sometimes. 

Also possible that Windows may have to be repair installed or clean installed as 
you would waste more time trying to fix it than just reinstalling if it isn't something 
simple.  If your drive isn't running in DMA, then there will be almost constant disk 
activity and Windows will be super slow, so slow you will be waiting more than doing 
anything.  Example, even on a 2 gig processor machine, it might take 3-6 minutes 
to boot up and even when done, even a small task will seem to take hours with constant 
disk activity and the processor load will be at 100% more than usual.

You probably already have DMA enabled on your hard disk, should be by default.

If you need different drivers for the chipset on the motherboard, it has to come 
from the motherboard manufacturer, the chipset maker, or the manufacturer of the 
computer if it is a big OEM type machine.  Without being able to see if you are running 
in DMA already, you won't know if you really have DMA enabled.  If you are already 
running in DMA, you obviously won't be able to speed anything up as far as the HDD. 
 There are no generic utilities that I know of that handle all types of different 
manufacturers of motherboards/chipsets. 

Who is the manufacturer of the machine or what brand and model motherboard do you 
have in your machine?  How much memory and what is the CPU speed? Need to know that 
info to be able to help at all or give you an idea as to what you should expect from 
your machine.

Thats an interesting point Keith and a good link thanks. 

As I've said mine as never been enabled all the years I've been using Win98SE. I 
shall have to give it a try to see if anything noticeable happens.

You may have a corrupted install if you have other errors too.  Have you tried to 
reinstall the system?

The Intel application/drivers for the chipset are here,

http://www.intel.com/support/chipsets/iaa/

but it shouldn't be needed for Win 9X.  Can't promise that it will work on your board. 
 It was mainly for Intel branded boards but should work for your chipset.  Just make 
sure to read everything that is important to make sure..  Intel's drivers may not 
be exactly right for your board.  Otherwise, you have to download drivers from Gigabyte, 
if they have them.  You would need the actual model number of the board though, which 
isn't in the info that you posted (only the chipset number is there).  Many times 
those utilities won't/can't determine the actual model of the board.  You would have 
to try and find it printed on the board somewhere, or have the actual owners manual 
that lists the model number.

If it were mine, I would take a spare HDD and do a clean test install of Windows, 
to see if the HDD DMA/PIO check box appeared under the drive listing.  If it does, 
then you have your answer.  The old install of Windows is damaged and may not be 
repairable, other than a repair install, or a clean install if that fails.

Can't help more than that without actually being able to get my hands on it to test 
it myself..  Good Luck!!

Everything should stay the same as it is, unless there is damage that Windows can 
not fix.  When you do a repiar install of Windows, it is actually installing a clean 
install of Windows, the same as if you wiped your drive and installed clean, except 
that Windows will try and import all of your settings data, drivers, and programs 
from the old install into the new one.  The issue is that sometimes those "defects" 
in the old system can be imported into the new install if WIndows doesn't have the 
"knowledge" on what NOT to import as far as damaged parts of the old system.

This is why Windows needs a certian/minimum amount of free space on the HDD to accomplish 
a repair install.  It simply doesn't "overwrite" the old install at all.  If Windows 
thinks it is successful, then it will delete the old install, and you can still be 
left with a damaged system.  About 25% of the time I will find this to be the case.

This is why I would recommend having a spare HDD to clean install Windows on to see 
if the DMA check box shows up and your other errors are fixed.  If it seems to be 
fixed, then you know that you have a damaged system.  I would then use the spare 
drive to image/clone you original drive to and then run the repair install on that, 
and keep your original drive safe if you don't want to risk losing your data and 
programs.  If the spare drive successfully repairs, your home free.  If it doesn't, 
then you know that you won't be able to repair the Windows install, and will have 
to end up using a clean install, reinstall your programs and transfer your data over 
to your new installation manually.  Don't let Windows do it with any "wizards".

Sorry for being long winded but over the years, I have my methods since I have had 
to (and still do, but not as much anymore) do this professionally from a data recovery 
standpoint. 

Bottom line is that one needs to have some spare hardware and make backup plans if 
you don't want to risk losing everything on a computer system, and expect to try 
and be successful in repairing it.  Just my experience..

I would strongly suspect you have hardware problems.  If that is the case, software 
or settings won't solve it.  Memory would be the first suspect.

Run this:  http://oca.microsoft.com/en/windiag.asp

Software diagnostics won't always be able to detect  errors but it would be a start. 
 Hardware testers are the only sure way of diagnosing hardware issues but you would 
have to be a service facility to afford that equipment.

The memory could be OK but the motherboard could be failing if errors are detected. 
 Not all that unusual as hardware ages...  You could also have hard drive issues 
so no way of really helping from a forum.  This very much sounds like a "hands on 
issue" to really test and determine you problems.  (either failing memory or HDD 
can cause data corruption and loss that can make Windows sick to non-functional)

Try the Intel App Accelerator from the link I posted earlier and see what happens. 
 Intel did have some issues that could be helped by installing their drivers.

One possibility, try re-registering the system DLL files.

Go to START > RUN and in the RUN box type the following -

  regsvr32 urlmon.dll

Then press the ENTER key. You should see a brief message that the dll has been successfully registered.

Do the same with the following, one at a time, pressing ENTER after each:

regsvr32 Shdocvw.dll
regsvr32 Actxprxy.dll
regsvr32 Oleaut32.dll
regsvr32 Mshtml.dll
regsvr32 Browseui.dll
regsvr32 Shell32.dll

Then download and install this Microsoft patch, which will install DLL files that are compatible with Win9x:

  MCREPAIR.EXE

Answer YES when prompted to replace a Newer file with an Older version.


Alternatively, open your bootup log in Notepad (it's a text file), and examine it to find any devices which failed to load properly on startup (i.e. search it for the word FAIL). That log file is in C: root, and is called BOOTLOG.TXT

It might be a hidden file, in which case open an MS-DOS box and type the following command first (so that Notepad will be able to open it):

C:\WINDOWS\COMMAND\ATTRIB.EXE C:\BOOTLOG.TXT -H
