The Abit iL-90MV BIOS 1.3 represents a significant update for users of motherboards based on the iL-90MV chipset. Released on September 22, 2006, this BIOS version incorporates several key improvements, bug fixes, and added functionalities designed to enhance system performance, stability, and compatibility with newer operating systems and technologies. This article provides a detailed overview of the changes implemented in Abit iL-90MV BIOS 1.3, outlining the benefits it offers to users seeking to optimize their systems.
Key Updates and Enhancements in Abit iL-90MV BIOS 1.3
This BIOS update focuses on addressing critical issues and introducing new features to improve the overall user experience. The key updates are as follows:
-
Addition of "Limit CPUID MaxVal" and "Virtualization Technology" Options: This update introduces two crucial settings within the BIOS interface: "Limit CPUID MaxVal" and "Virtualization Technology." These options provide users with greater control over processor behavior and enable support for virtualization technologies.
-
Limit CPUID MaxVal: CPUID (Central Processing Unit Identification) is an instruction that allows software to identify the processor’s vendor, family, model, and features. The "Limit CPUID MaxVal" option allows users to restrict the maximum CPUID value reported by the processor. This can be useful in scenarios where older operating systems or applications may not be fully compatible with newer processors and their extended feature sets. By limiting the CPUID value, users can potentially mitigate compatibility issues and ensure smooth operation of older software.
-
Virtualization Technology: This option enables or disables hardware-assisted virtualization, such as Intel Virtualization Technology (VT-x) or AMD Virtualization (AMD-V). Virtualization technology allows a single physical machine to run multiple operating systems or virtual machines simultaneously. Enabling this option can significantly improve the performance and efficiency of virtualization applications, making it an essential feature for users who rely on virtual machines for development, testing, or other purposes.

-
Fix for Performance Degradation with Disabled EIST: This update addresses a critical issue where disabling Enhanced Intel SpeedStep Technology (EIST) could lead to a noticeable drop in system performance. EIST is a power-saving technology that dynamically adjusts the processor’s clock speed and voltage based on workload. While disabling EIST can sometimes be desirable for overclocking or other performance-tuning purposes, it should not result in a significant performance decrease. This fix ensures that disabling EIST does not negatively impact system performance, providing users with the flexibility to configure their systems according to their specific needs.
-
Compatibility Fix for Microsoft Vista Installation: The Abit iL-90MV BIOS 1.3 resolves an issue that prevented users from installing Microsoft Vista on systems with the iL-90MV chipset. This compatibility fix ensures that users can successfully install and run the Vista operating system, addressing a major roadblock for those who wished to upgrade to or use Vista on their iL-90MV-based systems. This was a crucial update at the time, as Vista was the then-current operating system from Microsoft.
-
Support for DRAM and MCH Voltage Adjustment: This update introduces support for adjusting DRAM (Dynamic Random-Access Memory) voltage and MCH (Memory Controller Hub) voltage within the BIOS interface. These voltage adjustment options provide users with greater control over memory and chipset settings, allowing them to fine-tune their systems for optimal performance and stability.
-
DRAM Voltage Adjustment: Adjusting DRAM voltage can improve memory stability, particularly when overclocking or using high-performance memory modules. Increasing the DRAM voltage can help to compensate for voltage droop and ensure that the memory modules receive sufficient power to operate reliably at higher frequencies.
-
MCH Voltage Adjustment: The MCH, also known as the Northbridge, is a critical component that connects the CPU to the memory and other high-speed peripherals. Adjusting the MCH voltage can improve overall system stability, especially when overclocking the CPU or memory. Increasing the MCH voltage can help to stabilize the connection between the CPU and memory, reducing the risk of errors or crashes.
