TheBIOS/UEFIrefers to the firmware embedded on a memory chip on the motherboard. It serves as a software interface between the OS and the hardware, and like most software, it can be updated.
Normally, you don’t need to concern yourself with the BIOS version. But there are certain scenarios (hardware compatibility issues, booting issues, etc.) where a BIOS update may be necessary.
In such cases, you’re able to check your current BIOS version and compare it with the ones released by your system manufacturer. If any of the available ones seem worthwhile,you can consider updating.
Enter BIOS Setup to Check BIOS Version
If you’re in a situation where you need to find your BIOS version, chances are, youcan’t boot to Windowsat the moment. That’s not a problem though as you can check the BIOS version directly from your firmware interface.
Repeatedly press the BIOS Setup key (F2orDelfor ASRock) shown on the screen when booting.
On UEFI systems, you’re able to also hold Shift and restart, or force-restart 3 times in a row to enter the recovery environment. There, you can selectTroubleshoot>Advanced Options>UEFI Firmware Settingsto enter BIOS Setup.
Once youenter BIOS Setup, you’ll land on the main page where the BIOS version will be listed.
Check BIOS Version from System Information
The System Information tool in Windows displays detailed info about your system componentsincluding the motherboardand BIOS. If your system is online, that’ll be the fastest way to find the BIOS version.
You can also view all of this info from the command line if you want. PressWin + Xand selectTerminal. Enter thesysteminfocommand there.
Check Sticker on BIOS Chip
The original BIOS version is also physically marked on the BIOS chip embedded in your motherboard. If you haven’t updated the BIOS since purchasing the board, then this can be another possible way to find the BIOS version.
Check for a chip with the PX.XX label on the motherboard (e.g., P1.50). If you can’t find it, you can check the motherboard manual for the exact location.
