Enabling DMA mode on IDE channels will consume less processor cycles almost reduce consumption of processor cycles from 50% to 5%.  Windows 2K/2000 and Windows XP fail to enable DMA on IDE devices automatically. Though enabling DMA will not boost writing speed on to the disk, it will consume less processor cycles which can be used for another purpose.

By default PIO (Programmed Input-Output) transfer mode is set on IDE drivers in windows XP and 2000. PIO transfer mode consume more processor cycles because the central processor transfers data word by word or byte by byte.

When DMA transfer mode is enabled, small processor called DMA controller takes the burden of transferring data between IDE devices. Once the central processor starts the data transfer and transfers the control to DMA controller, the DMA controller looks after the data transfer and after completing the total transfer the control is transferred from DMA controller to central processor thus the central processor gets less involved in the transfer and so CPU cycles are saved which can be used by another programme.

Why a computer may use programmed Input-Output rather then DMA during data transfers?

Even after enabling DMA transfer mode frequently CD/DVD port falls to PIO mode due to scratched or unreadable CD-DVD.

During some situations PIO mode is enabled by default and these are as follows:

Due to repeated DMA errors – Windows XP will disable DMA mode and slips to PIO mode after encountering certain errors during data transfer operations. Possibly if more than 6 DMA transfer time-out occurs, windows enables PIO mode disabling DMA mode.

In the above case we can’t enable DMA for that device. Only solutions for this to be uninstall the device and reinstall it.

Methods to re-enable DMA

Through control panel:

1.      Device manager (Right click My computer and go to properties and click on device manager)

2.      Expand IDE ATA/ATAPI controller then Select Primary IDE channels then go to properties in that select Advanced Settings. Enable Transfer mode for Device 0 and also Transfer mode for Device 1 if not enabled already.

3.      Do the same for Secondary IDE channel?

Through Registry:

Editing the registry is the alternative way to enable DMA mode for IDE drivers.

1.      Start > Run

2.      Type Regedit.

3.      Now browse to the following key. HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Control \ Class \ {4D36E96A-E325-11CE-BFC1-08002BE10318}

4.      You will find the following subkeys:                0000 (for the IDE controller)
0001 (for the Primary IDE channel)
0002 (for the Secondary IDE channel)

5.      Open the sub-key and determine the channel on which troublesome drive is located.

6.      If the drive Is master then delete MasterIdDataChecksum value.

7.      If drive is master then delete SlaveIdDataChecksum named value.

8.      Reboot your windows XP/2K.

To Show thumbnails of pictures in Windows XP you have to enable thumbnail View. Once you enable Thumbnail view windows create a Thumbnail Database file (thumbs.db) in same folder and cache the thumbnails of images into this file. This way windows will show you preview of images faster next time you browse through same set of pictures.

If you like the Thumbnail view of images but not satisfied with quality or size of the thumbnails you can change default setting of these by using following registry hack.  (Always backup your registry before making any changes).

However Before changing these settings be sure that your computer have enough RAM and processing resources to handle these. As Thumbnail views can use a lot of system resources making your computer slow. If you increase the quality and size of thumbnail view, Browsing through files will require more time as building thumbnail is quite a slow process. Also if you have very large folders with thousands of images in it. Then it will be very time consuming and also your thumbnail cache can grow big.

Anyway Here the registry setting which needs to be setup in order to change the size and quality of thumbnails. (this works on XP and Vista Already have 3-4 different thumbnail views in built).

Open the registry and navigate to :

HKEY_CURRENT_USER\Software\Microsoft \Windows\CurrentVersion\Explorer

Create a new DWORD value called ThumbnailSize, and set the value between 32 and 256, and/or create another DWORD value called ThumbnailQuality, and set the value between 50 and 100.

First DWORD value defines size, higher the value, bigger the size of thumbnail. Also second keyword defines quality higher the value better would be quality, but of course it can not be better than your actual image :-) …

The key details are given below once again –

Key Details :

USER Key: [HKEY_CURRENT_USER\ Software\ Microsoft \ Windows\ CurrentVersion\ Explorer]
Value Name: ThumbnailSize
Data Type: REG_DWORD (DWORD Value)
Data Value: 32 – 256

USER Key: [HKEY_CURRENT_USER\ Software\ Microsoft \ Windows\ CurrentVersion\ Explorer]
Value Name: ThumbnailQuality
Data Type: REG_DWORD (DWORD Value)
Data Value: 50 – 100

Files present on other system opens very slowly and even it takes a long while to show name of available computers on network. Then you should try this registry hack.

This registry hack will not speed up your network access but it can also speed up your Internet Access speed. While using DialUp connection I have seen a boost of about 25% in internet speed where on higher speed connection it goes about 10-20%.

Increasing Network Browsing Speed

When you accessing your other computer on network, You get slow speed because of a special feature on Windows which is showing scheduled task on other computer. By default when you browsing Networked Computer, you cr computer will query and show the task which are scheduled on other computer. This process consumes some time and thus slowing down the process of showing computer and computer shares over the network. If your system is a bit slow you might feel like your system is hanged while it keep querying for these information.

Windows XP: Speeding Disk Access

The solution to this problem is very simple and straight forward, despite problem itself is a bit complex. As Scheduled task information is not useful for anyone unless you are configuring them remotely, you can safely disable this feature to speed up access to remote computers. This will increase the response time As your computer will not wait for information related to Scheduled tasks on remote computer. This can be done by editing registry and deleting related Registry key. To complete the process please follow the steps mentioned below -

  1. First you have to Open Registry Editor, for that click on the Start button and select Run.
  2. Then type regedit in the text box and click the OK button.
  3. Browse to ‘HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\ExplorerKey\NameSpace’
  4. This key will show all of the features that are enabled when you browse to a remote computer.
  5. In the NameSpace key folder there are two entries. One is “{2227A280-3AEA-1069-A2DE-08002B30309D}”  – this is for showing printer on remote computers. Another one is “{D6277990-4C6A-11CF-8D87-00AA0060F5BF},” this fetches information regarding scheduled tasks from remote computer.
  6. Delete second key, Close registry editor and restart your system, and you are done.

Quote:
If you don’t want to see shared printers on remote computer you can delete the other key mentioned in above steps as well  “{2227A280-3AEA-1069-A2DE-08002B30309D}”. This will further increase your browsing speed.
