Question about Compaq Presario Notebook
Que:-1 I want to use DMA Transfer mode instead of PIO Mode in my system. The problem is that my system is not taking Primary IDE Channel in which current trasfer mode is in Ultra DMA Mode 5. While system is taking Secondary IDE Channel in which current transfer mode is in PIO Mode. Few months ago it was working in Primary IDE channel and Transfer Mode was Ultra DMA Mode 5, But I Don't Know how and when it Switches to Secondary IDE Channel with PIO Mode.
Now Please tell me how can i bring my system back in Primary IDE channel with Ultra DMA Mode 5.
Company Name of my lapotop:- COMPAQ Product Name:- Presario C300 Product Number:- RE022PA#ACJ Serial Number:- CND6401MRF
Operating System:- Microsoft window xp Proeessional.
Service Pack - 2.0
BIOS Version : F.15
Device Type:- IDE ATA/ ATAPI Controllers.
This condition is caused by spyware,hard drive problems. First create a restore point, then run this script http://winhlp.com/tools/resetdma.vbs reboot and should do the trick. After XP tried to access the hard drive without success for any reason there is a register counter that downgrades the speed of the hard drive to PIO. Good Luck!

Go to Control Panel - click on System - Click on Hardware - Click on Device Manager - click on IDE ATA/ATAPI Controller.
Then right click on Primary IDE Chanel - then click on Properties - Then Advance Settings - For the Device 0 in Transfer Mode select DMA if available. Then Click OK.
You can also select DMA for Device 1 too

To enable DMA mode using the Device Manager
Open Device Manager.
Double-click IDE ATA/ATAPI Controllers to display the list of controllers and channels.
Right-click the icon for the channel to which the device is connected, select Properties, and then click the Advanced Settings tab.
In the Current Transfer Mode drop-down box, select DMA if Available if the current setting is "PIO Only."
If the drop-down box already shows "DMA if Available" but the current transfer mode is PIO, then the user must toggle the settings. That is:
Change the selection from "DMA if available" to PIO only, and click OK.•
Then repeat the steps above to change the selection to DMA if Available.
