3.2.2 Memory
The system mainboard uses Dual Inline Memory Modules (DIMM). Two pair's banks are available; each bank supports one CPU with Hyper Transport T echnology. The memory DIMMs accommodates Registered ECC (400/533/667) SDRAM DIMM and Double Data Rate Memory (DDR2) memory modules in 128MB, 256MB, 512MB, 1GB, and 2GB, 4GB combinations. Total memory size for one CPU is up to 32GB.
CAUTION
The system mainboard has strict memory type and timing requirements. Before you purchase DDR (Double Data Rate) memory for using in the system mainboard, you should contact your local reseller for a recommend list of system memory that has been validated on this system. It only supports registered memory, not supports unbuffered type memory.
CAUTION
To take advantage of the 128-bit interface, you must install DIMMs in pairs of two. DIMM0 and DIMM1 are paired; DIMM2 and DIMM3 are paired; DIMM4 and DIMM5 are paired; and slots DIMM6 and DIMM7 are paired. If you are only installing two DIMMs into a Memory Bank, it is recommended that you install them in slots DIMM6 and DIMM7 to get the full b a ndwidth.
NOTE
For optimal dual-channel DDR operation, installing DIMMs in pa ir is highly recommended. For two DIMMs per CPU, install them far from the CPU. For four or more DIMMs per CPU, install them same method to the CPU.

4. BIOS and Jumper Setting
4.1 BIOS
This chapter discusses the AMI BIOS Setup program built into the ROM BIOS. The Setup program allows users modifying the basic system configurations according to their requirements. This special information is then stored in battery-backed RAM so that it retains the Setup information when the power is turned off. The AMI BIOS installed in your computer system's ROM (Read Only Memory) is a custom version of an industry standard BIOS. The BIOS provides critical low-level support for standard devices such as disk drives and serial ports. The AMI BIOS has been customized by adding important, but non-standard, features such as password protection as well as special support for detailed fine-tuning of the chipset controlling the entire system. The rest of this chapter is intended to guide you through the process of configuring your system using Setup.
4.1.1 Starting BIOS Setup
The AMI BIOS is immediately activated when you power on the computer every time. The BIOS reads the system information contained in the CMOS and begins the process of checking out the system and configuring it. After finishing configuring the whole system, then BIOS will continue to seek an operating system on one of the disks, launch then turn control over to the operating system. While the AMI BIOS is in control, the Setup program can be activated in the way: By pressing the <DEL> key when the following message appears briefly at the bottom of the screen during the POST (Power On Self-Test).
27
4.1.2 Updating BIOS Setup
Creating a bootable floppy disk
A. DOS environment Insert a 1.44 MB floppy disk into the drive. At the DOS prompt, type: format A : /S then press <Enter>.
B. Microsoft® Windows® environment(Microsoft® Windows® 95/98 only) Insert a 1.44 MB floppy disk into the floppy disk drive. From your Windows desktop, click on Start, then select My Computer. Select the 3 1/2 Floppy Drive icon. Click File from the menu, and then select Format. A Format 3 1/2 Floppy
Disk window appears.
If you are using Windows
TM
, select "Create an MS-DOS startup disk" from the format
options field, then click Start.
Move the latest BIOS file to the bootable floppy disk. Using
"NVFLSHSC.EXE"
to update the BIOS
Update the BIOS using the NVFLSHSC.EXE utility in DOS environment. At the DOS prompt, type the command line: NVFLSHSC <filename> where "filename" means the latest (or original) BIOS file that you copied to the bootable floppy disk. The screen displays the status of the update process.
NOTICE
The BIOS information on the screen is for reference only. What you see on your screen may not be exactly the same as shown.
CAUTION
DO NOT shutdown or reset the system while updatin g the BIOS! Doing
so may cause system boot failure! When the BIOS update process is complete, the utility returns to the DOS prompt. The AMI BIOS is immediately activated when you power on the computer every time.
The BIOS reads the system information contained in the CMOS and begins the process of checking out the system and configuring it. After finishing configuring the whole system, then BIOS will continue to seek an operating system on one of the disks, launch then turn control over to the operating system.
