This manual is divided into 6 main sections, as described below: Introduction The introduction contains information on the main specifications for the K7VAT (K7VAT+) motherboard, the package contents and cautionary notes. Hardware Installation The Hardware Installation section is the most important in the manual.
With one 16-bit ISA expansion slot, which can accepts plug-in boards that control the sound, and other peripherals. AGP Slot The K7VAT (K7VAT+) comes with an AGP Slot with Support for AGP cards for high performance. The AGP 133MHz 4X mode is supported as well, further increasing system performance.
Page 8
USB interface With support for up to 4 USB ports, two on the back panel and two on-board, the K7VAT (K7VAT+) provides ample USB expansion room. IDE interface The K7VAT (K7VAT+) comes with an onboard PCI Bus Master IDE controller with two connectors that support four ATA66/33 devices on two channels (ATA100 is also supported for K7VAT (K7VAT+) boards that come with the 686B southbridge).
BIOS or through the VIA Hardware Monitor Software. System BIOS The K7VAT (K7VAT+) comes with a 2MB BIOS that provides, boot block write protection, and HD/ SCSI/ CD/ Floppy boot selection. DMI is also supported through BIOS, which allows hardware to communicate within a standard protocol creating a higher level of compatibility.
1-3 Package Contents The K7VAT (K7VAT+) Motherboard 1 Manual 1 Driver Installation CD-ROM 1 IDE ATA 66/100 Flat-Cable 1 Floppy Disk Drive Flat-Cable Please verify that all items listed above are included in your motherboard package. If one of the items is missing, please contact the dealer where you bought your motherboard.

This connector is keyed and can only be installed one way. If you use a heatsink assembly that has two cooling fans, connect one to FAN 1 and the other to FAN z3. For more information on the FAN connectors, refer to the FAN connector section later in this section. K7VAT System Board...
100MHz with a multiplier setting of 8x. Frequency The K7VAT (K7VAT+) motherboard allows for setting of the frequency through the BIOS. To change the CPU frequency, go to the Voltage / Frequency Control page in the BIOS setup, the CPU Host / PCI Clock item will allow you select the CPU frequency. This is explained in more detail in the BIOS section.
Page 17
This potion tells the clock generator what frequency to send to the CPU, DRAM and the PCI bus. This allows the selection of the CPU’s External Frequency(or Bus Clock). The Bus Clock multiplied by the Frequency Multiple equals the CPU’s Intemal frequency (the advertifed cpu speed). K7VAT System Board...

Page 29
The BIOS first assigns the interrupts to the ISA PnP cards from the interrupt pool. The interrupts (if available) are assigned in the following order: 15, 11, 10, 12, 14, 3, 4, 5, 7, 9. As mentioned, if ACPI if enabled, IRQ 9 will not be available. K7VAT System Board...

Chapter 3 Software Installation It is recommended to do a clean installation of Windows when you first install your K7VAT (K7VAT+) motherboard. Immediately after installing Win98 or Win2000 you should install the latest VIA drivers for the motherboard. The original VIA drivers are included on the driver CD which accompanied this motherboard, but the latest drivers can be found at http://www.via.com.tw/drivers/index.htm...
Some users have the onboard IDE controllers disabled, because SCSI disks are used. Installation of the VIA 4in1 drivers under Windows98 then gives a "Registry error! Please reboot computer" error message while the setup file unpacks. Enabling the IDE controllers during the installation will solve this issue. K7VAT System Board...
BIOS is necessary to support new devices that were not on the market at the time the motherboard was released. For the physical location of the BIOS FLASH ROM IC on your K7VAT (K7VAT+) motherboard, refer to the picture below: BIOS The BIOS IC is inserted in an IC socket, which means that it can be removed and exchanged for another IC if necessary.
Go into the Frequency/Voltage Control page to adjust your CPU speed and voltage (please make sure the CPU voltage matches your CPU specs, in case of doubts leave it to ‘default’). Save your settings and you are done. K7VAT System Board...
