BIOS and UEFI Updates

Correct Answer: Using BIOS manufacturer's dedicated utility

The best method for updating the BIOS is to use the dedicated utility provided by the BIOS manufacturer. This ensures compatibility and reduces the risk of errors during the update process. Using Windows System Update or Device Manager to update BIOS is not recommended, as these methods are not designed for BIOS updates and may cause issues. Flashing the BIOS at startup using a USB drive is a valid method, but it is more complex and should only be used if the manufacturer's utility is not available or functioning properly.

Correct Answer: .CAP

When updating a motherboard's UEFI firmware, the correct file type to choose is .CAP. UEFI firmware update files are typically provided in the .CAP (Capsule) format. The other file types listed are not commonly used for UEFI firmware updates: .ISO is used for optical disc images, .ROM is an older firmware format used with legacy BIOS, and .BIN is a generic binary file format that is not specific to UEFI firmware updates.

Correct Answer: Ensuring a stable power supply

The most important prerequisite for a successful BIOS/UEFI update is ensuring a stable power supply. This update is a critical process that can potentially render a computer system unusable if it fails. A stable power supply ensures that the update process is not interrupted, which could happen if there is a power outage or if the power fluctuates. If the BIOS/UEFI update is interrupted, it can corrupt the firmware which may lead to a complicated recovery process or in worst cases, require a motherboard replacement. Running multiple updates simultaneously is not recommended since it can lead to conflicts and potential problems during the update process. BIOS/UEFI updates should be done individually and with careful attention. Performing the update over a wireless network is risky due to the potential instability of wireless connections. An interruption in network connectivity could result in an incomplete or corrupted update. It is safer to perform these updates using a wired connection or from a local source such as a USB flash drive. Disconnecting all USB devices except for the updater media is generally a good practice to avoid any potential conflicts but it is not a prerequisite. The critical point is to ensure that the specific device being used for the update process is connected and recognized by the system.
