MicroATX Form Factor; 24.4cm x 21.0cm 1. Due to different Linux support condition provided by chipset vendors, please download Linux driver from chipset vendors' website or 3rd party website. 2. Most hardware/software vendors no longer offer support for Win9X/ME. If drivers are available from the vendors, we will update them on the GIGABYTE website. (Note 1) Due to Windows 32-bit operating system limitation, when more than 4 GB of physical memory is installed, the actual memory size displayed will be less than 4 GB. (Note 2) To use the onboard D-Sub, DVI-D, HDMI, you must install an Intel CPU with integrated graphics. (Note 3) The DVI-D port does not support D-Sub connection by adapter. (Note 4) You can use only one of the onboard digital graphics ports (e.g. DisplayPort, HDMI, and DVI-D) for output when in the BIOS Setup program or when during the POST screens. (Note 5) For optimum performance, if only one PCI Express graphics card is to be installed, be sure to install it in the PCIEX16 slot.

Remark

(Note 6) The PCIEX16 slot operates at up to x4 mode when ATI CrossFireX is enabled. (Note 7) Whether the CPU/system fan speed control function is supported will depend on the CPU/system cooler you install. (Note 8) Available functions in EasyTune may differ by motherboard model. * The entire materials provided herein are for reference only.
