This article provides information regarding the JetWay NC81-LF Bios A02 update. This BIOS update addresses a specific issue related to memory reporting within the operating system when using GPU-Z, a popular graphics card information utility. It also includes crucial instructions for safely and correctly flashing the BIOS to your JetWay NC81-LF motherboard. Incorrectly flashing the BIOS can lead to system instability or even render the motherboard unusable, so it is vital to follow these instructions carefully.
Understanding the Update: Addressing the 6MB Sideport Issue
The primary purpose of the JetWay NC81-LF Bios A02 update is to resolve a reporting error where GPU-Z incorrectly identifies the motherboard’s sideport memory as only 6MB. This issue does not necessarily indicate a functional problem with the motherboard or graphics card, but rather a miscommunication between the BIOS and the GPU-Z software. The updated BIOS aims to correct this reporting discrepancy, providing accurate information about the system’s memory configuration.
Important Instructions for Flashing the BIOS
Before proceeding with the BIOS update, it is imperative to understand and adhere to the following instructions. Failure to do so could result in serious system errors.
1. Post-Flash Configuration: Load Optimized Defaults or Clear CMOS
After successfully flashing the BIOS, it is essential to either load Optimized Defaults in the BIOS setup or clear the CMOS (Complementary Metal-Oxide-Semiconductor). This step ensures that the system recognizes and utilizes the new BIOS settings correctly. Loading Optimized Defaults typically resets all BIOS settings to a pre-defined, stable configuration. Clearing the CMOS achieves a similar result, effectively resetting the BIOS to its factory default state. Consult your motherboard manual for instructions on how to clear the CMOS, as the process varies depending on the motherboard model.
2. BIOS Upgrade Procedure: A Step-by-Step Guide
The recommended BIOS upgrade procedure involves a specific sequence of actions:
- Flash BIOS: This is the primary step where the new BIOS file is written to the motherboard’s BIOS chip. Ensure you have the correct BIOS file for your specific motherboard model (JetWay NC81-LF in this case).
- Enter into BIOS: After the flashing process is complete, restart your computer and enter the BIOS setup utility. This is usually done by pressing a specific key (e.g., Delete, F2, F12) during the boot process. The key to press is usually displayed on the screen during startup.
- Load Optimized Defaults: Within the BIOS setup utility, locate the option to "Load Optimized Defaults" or similar. Select this option to reset the BIOS settings.
- Save and Exit: Finally, save the changes and exit the BIOS setup utility. The system will restart, and the new BIOS will be active.
3. AWARD Flash Utility: Version 8.83 or Newer is Required
The JetWay NC81-LF Bios A02 update requires the use of the AWARD Flash Utility version 8.83 or a later version. Using an older version of the AWARD Flash Utility may lead to incomplete or corrupted BIOS flashing, potentially causing system instability. The AWARD Flash Utility is a software tool designed specifically for flashing AWARD BIOS chips, which are commonly used on older motherboards. Make sure you download the correct version of this utility before attempting to update the BIOS.
4. SPI BIOS and AWARD Flash Utility Compatibility
This instruction highlights a critical compatibility issue. Some motherboards utilize Serial Peripheral Interface (SPI) BIOS chips. Updating these motherboards with older versions of the AWARD Flash Utility can cause a system crash. While the JetWay NC81-LF may not necessarily use an SPI BIOS, it’s crucial to be aware of this potential issue when working with other motherboards.
5. AWDFLASH Parameters: Necessary for Successful Flashing
When using the AWDFLASH utility (version 8.83 or newer) to flash the JetWay NC81-LF Bios A02, specific parameters are required to ensure a successful update. These parameters are "/cd/cp/ch/wb/qi". These parameters instruct the AWDFLASH utility to clear the DMI (Desktop Management Interface) data, clear the PnP (Plug and Play) data, clear the CMOS checksum, write the boot block, and perform a quiet installation. Omitting these parameters may result in an incomplete or incorrect BIOS flash.
6. Specific Motherboard Series and Award Flash 8.27B
This instruction addresses a specific set of older motherboards: (P4XFA P4XFB P4XFBU P4XFCP P4XFCU P4XFM P4XFMP P4XFMU V6DP V6DU V6FP V6FU). These motherboard series require the use of the older Award Flash 8.27B tool. This instruction does not apply to the JetWay NC81-LF. It is important to note that mixing the wrong flashing tool with the wrong motherboard can lead to irreversible damage.

- Wims BIOS: (Wims BIOS is a BIOS repository, but file availability varies.)
- Motherboard Manufacturer Archives: (While JetWay might not have it readily available, check any archived pages.)
- TechPowerUp BIOS Database: (TechPowerUp sometimes archives BIOS files; search for NC81-LF.)
Conclusion: Updating the JetWay NC81-LF BIOS
The JetWay NC81-LF Bios A02 update specifically addresses a reporting issue with GPU-Z, ensuring accurate memory information is displayed. This article has outlined the necessary steps and precautions for flashing the BIOS safely and effectively. Remember to use the correct AWARD Flash Utility version (8.83 or newer), apply the required parameters, and load Optimized Defaults or clear the CMOS after the update. While the JetWay NC81-LF might be an older board, following these instructions carefully will increase the likelihood of a successful BIOS update and a stable system. Always back up your existing BIOS if possible, and proceed with caution when flashing any BIOS.
