Windows NT – Easily Enable Ultra DMA IDE drives
Support DMA IDE drives is much more difficult under NT4 than under his contemporaries in the branch Windows 9x. Indeed, those who know the system know that there is no device manager tree, as can be found in virtually all other Windows, including XP 2000 and its successors, and where in order to enable DMA improve the speed of his records is a breeze.
We will enable DMA by following a few simple steps.
1 – Check NT service pack
The UDMA is theoretically supported from SP2 or SP3. This means, according to Microsoft, that support only works well since the SP4. Conclusion: Install SP6a to have really no problem … If you are not current on that side, you will get an error message in step 3, at the launch of the utility.
2 – Download the Microsoft utility to change the registry
it is possible to enable DMA by changing hand the registry. This maneuver is always risky, however, I would advise against it, because when NT4 is not happy, is the relocation provided. Papa Microsoft has cooked up a nice little utility that comes with the CD of NT4 with SP4 or higher (Directory support, dmacheck).
This utility is in English, but it works for all languages
3 – Install and use the small utility
Double-click your little program. A window appears and disappears back before you had time to read it.This is normal, the program has unpacked and copied to the root of the hard drive where you installed your system. So go to the root of your drive (C: in most cases). A small program that you have never seen before awaits you: dmacheck.exe. Run it by double-clicking. Enable UDMA for IDE compatible or Channel (s) (Channel 0 is the primary IDE controller, Channel 1 secondary controller, if you do not understand what I say, I advise you first of all to consult the Article on FDI in kioskea to understand a little what happens).
Once done, click OK, then reboot. Or if the channels you have enabled DMA and disk drives attached to them are compatible, everything will go perfectly. (Note that the DMA is already an old technology, you really have your readers are from Babylon to not be compatible.)
