EVGA E758 X58 SLI Bios 49

This article provides information regarding the EVGA E758 X58 SLI Bios 49 update. It outlines the key improvements introduced in this version and details the necessary steps to perform the BIOS update using various methods. Understanding the BIOS and the update process is crucial for maintaining optimal system performance and compatibility. The EVGA E758 X58 SLI Bios 49 is a critical component for users of this specific motherboard.

What’s New in EVGA E758 X58 SLI Bios 49:

This BIOS update addresses two specific issues:

• Virtualization Technology Shutdown: This update resolves an issue where the system would shut down unexpectedly when Virtualization Technology (VT-x) was enabled in the BIOS settings. Virtualization Technology allows a single physical machine to run multiple operating systems or virtual machines simultaneously. This fix is essential for users who rely on virtualization for development, testing, or running multiple environments.

• ICH Voltage Default: The update sets the default voltage for the Intel ICH (I/O Controller Hub) to 1.1V. The ICH manages communication between the CPU and various peripherals, such as storage devices, USB ports, and network interfaces. Setting a stable and appropriate default voltage for the ICH contributes to overall system stability and reliability.

Understanding the BIOS (Basic Input/Output System):

The BIOS is a firmware program embedded on a small chip on the motherboard. It is the first software to run when a computer is powered on. Its primary functions include:

• Power-On Self-Test (POST): The BIOS performs a series of diagnostic tests to ensure that essential hardware components, such as the CPU, memory, and graphics card, are functioning correctly.
• Bootloader: The BIOS identifies and loads the operating system from a storage device (e.g., hard drive, SSD).
• Hardware Configuration: The BIOS allows users to configure various hardware settings, such as boot order, CPU clock speeds, memory timings, and fan speeds.
• System Services: The BIOS provides basic input/output services for the operating system to interact with hardware devices.

Importance of BIOS Updates:

BIOS updates are released by motherboard manufacturers to address bugs, improve performance, enhance compatibility with new hardware, and add new features. Updating the BIOS is a critical task for maintaining a stable and up-to-date system. However, it’s essential to follow the instructions carefully to avoid potential issues. If your system is utilizing the EVGA E758 X58 SLI, the Bios 49 update is something to consider.

BIOS Update Methods for EVGA E758 X58 SLI Bios 49:

The following methods can be used to update the EVGA E758 X58 SLI BIOS to version 49:

1. CD Method (Requires a Blank CD and CD Rewritable Drive):

• Download the .iso file: Download the file from a reliable source. Direct download link: TechSpot

• Burn the .iso image: Use CD burning software (e.g., Nero, Alcohol 120%, MagicISO) to burn the downloaded .iso image onto a blank CD. Ensure that you burn the image as an image, not as a regular data file.

• Boot from CD: After burning, insert the CD and restart your computer. Enter the BIOS setup utility (usually by pressing DEL, F2, or F12 during startup) and load default settings. Save the changes and exit the BIOS. Then, set the CD drive as the primary boot device in the BIOS or press the appropriate key (usually ESC, F10, or F11) during startup to select the CD drive as the bootable device.

• Flash the BIOS: The system will boot from the CD and initiate the BIOS flashing process. Do not interrupt the process.

• Post-Flash Steps: After the flash is complete, remove the CD and power off the computer completely. Turn the computer back on and enter the BIOS setup utility. Load default settings, save the changes, and exit the BIOS.

2. USB Floppy Method (Requires a Floppy Disk and Floppy Disk Drive):

• Download the executable: Download the file from a reliable source. The filename should be similar to E762_49.exe.

• Prepare the Floppy Disk: Insert a blank floppy disk into the floppy drive and run the downloaded executable. This will extract the necessary BIOS files onto the floppy disk.

• Boot from USB Floppy: Restart your computer and enter the BIOS setup utility. Set the USB floppy drive as the primary boot device or press the appropriate key during startup to select the USB floppy drive as the bootable device.

• Flash the BIOS: The system will boot from the floppy disk and initiate the BIOS flashing process. Do not interrupt the process.

• Post-Flash Steps: After the flash is complete, remove the floppy disk and power off the computer completely. Turn the computer back on and enter the BIOS setup utility. Load default settings, save the changes, and exit the BIOS.

3. USB Flash Drive Installation:

• Download the .bin file: Download the file from a reliable source. The filename should be similar to E76249.bin.
• Prepare the USB Drive: This method usually requires a specific process for formatting the USB drive and making it bootable. It is highly recommended to consult the specific thread mentioned in the original instructions (thanks 30h6) for detailed steps. This is due to the fact that the EVGA E758 X58 SLI’s BIOS may require a particular format for it to read the USB drive.
• Flash the BIOS: Restart your computer and enter the BIOS setup utility. Set the USB drive as the primary boot device or press the appropriate key during startup to select the USB drive as the bootable device.
• Post-Flash Steps: After the flash is complete, remove the USB drive and power off the computer completely. Turn the computer back on and enter the BIOS setup utility. Load default settings, save the changes, and exit the BIOS.

Important Warnings:

• Do not interrupt the flashing process: Never restart or turn off your computer while the BIOS is being flashed. This can corrupt the BIOS and render your motherboard unusable.
• Do not flash with overclocked settings: Reset your system to default clock speeds before flashing the BIOS. Overclocking can introduce instability and increase the risk of a failed flash.
• Power down and Clear CMOS: After flashing the BIOS, it is always recommended to power down the computer completely and clear the CMOS (Complementary Metal-Oxide-Semiconductor) memory. This will reset the BIOS to its default settings and ensure proper operation. The CMOS can usually be cleared by using a jumper on the motherboard or by removing the CMOS battery for a few minutes.

Alternative Download Links:

Due to the age of this BIOS update, finding direct download links can be challenging. Here are some alternative resources where you might find the EVGA E758 X58 SLI Bios 49:

1. EVGA Official Forums: Check the EVGA forums for user uploads and archived BIOS files.
2. BIOS Repository Websites: Websites like BIOSAgentPlus or similar archives might host older BIOS versions.
3. Third-Party Driver Websites: Some driver download websites may host the BIOS file, although exercise caution when downloading from unofficial sources.
4. TechPowerUp VGA BIOS Collection: Although primarily for graphics cards, TechPowerUp sometimes archives motherboard BIOS files.
5. Win-RAID Forums: This forum focuses on storage drivers and BIOS modding, and users may have archived BIOS files.

Conclusion:

Updating the BIOS on your EVGA E758 X58 SLI motherboard to version 49 can resolve specific issues and improve system stability. However, it is crucial to follow the instructions carefully and take the necessary precautions to avoid any potential problems. The EVGA E758 X58 SLI Bios 49 provides important fixes for virtualization and ICH voltage. Remember to download the BIOS file from a trusted source and consult the motherboard manual for specific instructions.
