Please read the notes carefully before updating BIOS.
1.Do not update the BIOS if the system is running fine. Unsuccessful BIOS flash may cause the system fails to boot up. The manufacturer is not responsible for any BIOS flash failure.
2.Make sure your M/B PCB version number first, and then read the updated description & special note carefully to check if the new BIOS version patch pertain to your current problem.
(How to recognize the M/B PCB version)
3.Please DO NOT reboot system,unplug power supply and remove battery during BIOS update process.
4.It is recommended to use the updated flash utility included in each BIOS download package.
(How to use flash utility).

What is the maximum CPU and HDD capacity supported on L4VXA2 v1.0x? 

L4VXA2 v1.0x maximum CPU and HDD supported information as below,
HDD: 250G
CPU: Pentium 4 400Mhz FSB (256K/512K L2 cache) CPU – 2.2G.
           Pentium 4 533Mhz FSB (512K L2 cache) CPU – 3.06G 
           Celeron 400Mhz FSB (128K L2 cache) CPU – 2.8G

Does L4VXA2 support Hyper-Threading Pentium 4 CPU? 

Yes, the L4VXA2 V1.0A supports Intel's Hyper-Threading technology. If you install a CPU with Hyper-Threading such as P4 3.06G on this MB, there is "Hyper-Threading technology" item in BIOS to let you enable or disable this new feature.

How many channels does the onboard audio of L4VXA2 V1.0A support? 

The L4VXA2 V1.0A comes with VIA VT1612A Audio chip which supports 2 channels only.

Does L4VXA2 V1.0A support 80GB HDD & higher? 

Yes, the L4VXA2 V1.0A supports hard drive capacity up to 160GB.

Which version of L4VXA2 supports memory module/1GB/128 x 4? 

The L4VXA2 does not support 128 *4 of 1G memory but 1M, 2M, 4M, 8M, 16M, 32M, 64M, 128M, x 8/16/32 DRAMs.

How to set up sound driver for DOS & how to adjust the audio output for 3D surround (a rear and front speakers)? 

The L4VXA2 only supports 2.1 channel audio output. Please use 2.1 speakers for this M/B audio output. It doesn't support MS-DOS Audio driver (VIA VT1612A AC'97 Audio CODEC). Some games may come with in-box driver (Sound blaster or something else) that is compatible with this audio mode.
