           AMD Morgan 200Mhz FSB CPU - 1.3G 
           AMD Athlon 200Mhz FSB CPU - 1.4G AMD Athlon 266Mhz FSB CPU - 1.4G 
           AMD Palomino 266Mhz FSB CPU - 1.2G 
           AMD Athlon XP (0.18u) 266Mhz FSB CPU - 2000+ AMD Athlon XP (0.13u) 266Mhz FSB CPU - 2200+

Aktualisieren Sie das BIOS auf JAMA V3.2D zur Fehlerbeseitigung. Auf Empfehlung von AMD wurde ein wenig BIOS-Code (CLK_CTL) hinzugefügt.

V3.3B-BIOS konnte das instabile Verhalten des 266FSB beseitigen.

You are not allowed to apply K7VZA V3.0 BIOS on K7VZA V1.0 MB because these 2 PCBs come with different HW designs.

We suggest you flash BIOS by DOS utility under pure DOS mode, the procedures is as below,
1. Copy BIOS file and flash utility to a disk.
2. Boot from Floppy with the bootable disk, then insert above disk.
3. Execute awd832b XXX.bin /sn/py/r under A:>
4. Load default setting.

Please help to check your PCB version, and follow lists to select the CPU for this M/B.
1. PCB 1.0: Duron 800MHz(FSB:100 MHz) & Althon 1.2GHz(FSB 100), and support BIOS is 1.2f version.
2. PCB 1.0A: Duron 800MHz(FSB:100 MHz) & Althon 1.2GHz(FSB 100), and support BIOS is 1.2f version.
3. PCB 3.0: Athlon 1.4G(133), Palomino 1.3G(133), Athlon XP 2000+(133, 0.18u) & Athlon XP 2600+(133, 0.13u),
    and support BIOS is 3.7 version.

The K7VTA V3.0 can suuport CPU to AMD Athlon XP 2600+(0.13u) and HDD can support to 250GB.
Below are Flash BIOS procedures
1.Please update BIOS under pure DOS mode
2. Boot from a bootable disk.
3. Insert a disk with awd832b.exe and vza37.bin ROM file.
4. Execute "awd832b vza37.bin /sn/py/r" command under A:>
5. Load the default setting.

Yes, the V3.7 BIOS of K7VZA can support AMD Athlon CPU to 2600+ (0.13u/FSB 266MHz).

不支持, K7VZA V1.0 仅仅能支持最大136GB的硬盘.

The K7VZA doesn't support AMD Sempron CPUs. It supports AMD Athlon XP CPUs up to 2600+.

Please refer to attached file for the USB pin definition of K7VZA V3.0.

Please download the audio driver from our ECS website as below. Please refer to Product page - Download tag

Please update the K7VZA V3.7 BIOS to support AMD Athlon XP 2400+ & 2600+ CPU (0.13u).
Flash BIOS procedures are as follows
1. Extract the utility to a disk and copy BIOS .bin file to this disk.
2. Boot from floppy with bootable disk.
3. Insert the disk with utility and BIOS
4. Execute the awd832b XXX.bin /sn/py/r
5. Load the default setting.

Yes, please update K7VZA V3.0 BIOS V3.7 to support the Athlon XP 2600+(133/0.13) CPU.

The K7VZA V3.0 supports AMD Palomino to 1.2GHz(133MHz) and AthlonXP to 2600+(0.13u/133MHz).

The K7VZA only supports Duron to 950MHz/FSB 100MHz CPU. So it does not support a Duron 1800+/FSB 133MHz CPU.

Since the 4X AGP slot design of hardware that is difference from 8X AGP slot, so we don't guarantee all of the 8x garphic card can suit with your M/B.
