Determining which version of BIOS you currently own on your motherboard usually involves restarting your PC a couple of times and paying really close attention. Yet an easier way is to find the BIOS version from inside the Windows Registry – without rebooting or going through the hectic processes involved otherwise.
Click on Start and then initiate the Run process from the start menu
In the text box in the Run, type regedit and click OK. This will open the “Registry Editor” program.
Be careful : Do not make any changes to any entry anywhere in Registry Editor to avoid causing serious system issues. These steps only direct you to view a registry entry, not to make changes.
3. Locate the HKEY_LOCAL_MACHINE folder under My Computer and click on the (+) sign next the folder name to expand the folder.
In the resulting folders, locate and click on the (+) sign next to HARDWARE to expand this folder.
4. In the resulting folders, locate and click on the (+) sign next to DESCRIPTION to expand this folder.
5. In the resulting folders, locate and click on the System folder.
6. In the results that appear in the window on the right, locate the SystemBiosVersionand SystemBiosDate entries.
7. The data in the SystemBiosVersion field contains the BIOS version for your motherboard. This field may also contain additional information such as the chipset manufacturer and BIOS manufacturer.
8. The data in the SystemBiosDate field contains the calendar date associated with the current BIOS version on your motherboard. The BIOS date can be useful in determining the current BIOS version from a motherboard manufacturer’s website if the version is not clear in the SystemBiosVersion field.
9. Close Registry Editor without making any other changes.
Once you have successfully completed the above given method you would have known your bios version without going through any mess of restarting and all.
