Computer hardware tips & tricks

Install supplemental device drivers

Windows normally comes with a set of default device drivers which are preinstalled on your PC or are made available as a requirement on your original operating system discs. However, it is impractical and impossible for an operating system to always possess all the drivers, especially considering device drivers are often in need of updates. Some of the drivers normally require supplemental device drivers which are acquired from the hardware device manufacturer. Usually, a new hardware device comes with a disc that contains its device drivers. But otherwise you have to download the drivers from the official website of the device manufacturer.

Some of these drivers which require supplemental device drivers are for hardware devices that are not plug-n-play compatible, 3rd party HAL or Hardware Abstraction Layers, mass storage controllers like RAID and SCSI and plug & play drivers which operating systems do not have. To get better results when you are working with 3rd party drivers you must ensure that these drivers are digitally signed by Microsoft or another reputable technology business entity. This digital sign is said to be a symbol which every device driver possesses after being tested and this sign cannot be changed or even overwritten by any other program, at least legally.

In order to recognize if the device drivers are digitally signed or not, you can run the “sigverif.exe” function. Click the Windows “Start” button and select “Run” where you will have to enter “sigverif” and press Ok. In case you have clicked on the “Advanced” button then you will get a chance to create a function of sigveif log. You can use this function to scan various unsigned device drivers on your operating system. However, to change the unsigned device drivers, in Windows XP you have to go to the Control Panel option and choose System. Then, click the tab named hardware and adjust it to warn, block or ignore.

You can even view signed device drivers in the Device Manager utility after you right click on the device and choose Properties to select the drivers tab and then choose the driver details. The files of device drivers can end with several file extensions which include DLL, INF, SYS, TXTSETUP.SIF and TXTSETUP.OEM files. However if you need to perform any unattended installation then the drivers must be accessible at the time of this process. The installation process can fail in case the setup cannot locate these drivers. But to avoid this problem you need to either copy the device drivers to the destination hard drive or to the distribution share.

You can even update or alter these device drivers after going in the device manager where you can get the complete list of installed hardware’s in your operating system. Over there you can view updates, details, rollbacks, disable and enable options of the device drivers. A dialog appears if the current device driver is not functioning properly. In order to update these drivers for peripherals such as printers which are not listed on the device manager you need to select Control Panel and choose printers or modems and right click to select properties and then click on the advanced tab after that you have to select new drivers. Follow these instructions properly and search for new device drivers successfully.
