This article provides information regarding a specific BIOS update, version 4PEA3711, for the EPoX EP-4PEA and EP-4PEA+ motherboards. It outlines the fixes and improvements included in this BIOS release, along with relevant technical details and download information. Understanding BIOS updates is crucial for maintaining system stability, compatibility, and performance. This article serves as a historical record of a specific update from 2003.
Overview
The EPoX EP-4PEA and EP-4PEA+ motherboards were popular choices for users building or upgrading their PCs in the early 2000s. These motherboards supported Intel Pentium 4 processors and offered a range of features for their time. A BIOS (Basic Input/Output System) is firmware embedded on a motherboard that initializes hardware components during the boot process and provides runtime services for the operating system and programs. Updating the BIOS can address compatibility issues, improve performance, and resolve bugs.
What’s New in BIOS Version 4PEA3711
This particular BIOS update, version 4PEA3711, released on July 25, 2003, included several key improvements and fixes:
- Improved IDE DMA Transfer: This update aimed to enhance the speed of IDE (Integrated Drive Electronics) data transfers, particularly within the DOS environment. This improvement was specifically targeted at enhancing the performance of disk imaging software like Ghost. DMA (Direct Memory Access) allows devices to directly access system memory without involving the CPU, leading to faster data transfer rates.
- Updated CPU Microcode: CPU microcode is a set of instructions embedded within the CPU itself. Updating the microcode allows the motherboard to correctly identify and support new CPUs. This was a common practice as new processor revisions were released, ensuring proper functionality and preventing potential compatibility issues. This ensures the EPoX EP-4PEA and EP-4PEA+ motherboards can properly utilize newer CPUs.
- Solved Incompatibility with Korean Win98SE and VGA Card [MX440]: This fix addressed a specific compatibility issue encountered when using the Korean version of Windows 98 Second Edition (SE) with the NVIDIA GeForce MX440 graphics card. This highlights the importance of BIOS updates in resolving localized compatibility problems.
- Solved Data Loss Issue with HPT372N Controller: The HighPoint HPT372N was a popular IDE RAID controller chip often integrated on motherboards to provide enhanced storage capabilities. This update addressed a data loss issue that could occur when copying large data files while using the HPT372N controller. Data integrity is paramount, and this fix was crucial for users relying on the RAID functionality.
