Please follow the tables to install DDR memory module. Otherwise, system may not boot up or running properly. AMD recommend use paired DDR memories (same size and speed) for running at 128bit memory bandwidth. !§SS!‥ represents Single Side DDR memory module. !§DS!‥ represents Double Side DDR memory module. !§NA!‥ represents Not Available. !§*!‥ (Star sign) represents leave the DIMM socket empty.

If the motherboard can support Sempron CPU, but the CPU name in POST screen does not show correctly. The problem is because the BIOS version too old. Please update the latest BIOS on our website for supporting the Sempron CPU name. https://www.biostar.com.tw/support/bios/index.php3 For the K7 motherboard, the CPU clock jumper need to set to 333 MHz. Then the CPU will run at correct speed and system will show the correct CPU name in POST screen. Please refer user manual for the correct CPU jumper setting. https://www.biostar.com.tw/support/manual/socket.php3?socket=a

For the K8 socket 754 models support Sempron CPU K8NHA Grand, K8NHA-M, K8NHA-M Grand, K8NHA Pro, K8VHA Pro, K8VGA-M For the K7 socket A models support Sempron CPU M7NCD, M7NCD Pro, M7NCD Ultra, M7NCD Ultra 8.X, M7NCG, M7NCG 400, M7NCG 400 7.X, M7VIZ, M7VIZ 7.X, M7VIZ 8.X, M7VIZ 400, M7VIT Grand, M7VIT 800, M7VIT Bravo, M7VIT Pro

To install NVIDIA RAID technology on a new Windows XP operating system, a floppy disk with the NVIDIA IDE drivers must be created to enable installation of NVIDIA RAID
To create the NVIDIA IDE drivers floppy disk, the end user must
1. Copy these files from the NVIDIA nForce?driver directory (IDE/WinXP or
Win2K) onto a formatted floppy disk
Txtsetup.oem
Nvraid.sys
NvAtaBus.sys
NVRAID driver download

2. Go into the BIOS setup menu and enable RAID
a. In the BIOS menu, specify which disks should be dedicated to RAID
b. Exit the BIOS menu and reboot
3. At the RAID ROM screen, press F10 to enter RAID setup
a. Create a RAID array and add disks to it
b. Select "Yes" when asked to clear disk data
c. Reboot system
4. Select F6 when prompted
5. Install the NVIDIA RAID drivers created on the floppy disk
Select both the RAID and IDE drivers from the floppy to enable RAID functionality
6. Continue with the driver installation process

Please update the latest BIOS which support AMD Sempron CPU for the motherboard. https://www.biostar.com.tw/support/bios/bios.php3?model=M7NCD%20Ultra%20(8.x)

iDEQ200V need to manually set the CPU clock jumper.
By factory default, CPU clock jumper is set to FSB 266 MHz.
If use FSB 333 MHz CPU on the iDEQ200V, all yellow jumper caps on JCLK1 need to remove. FSB 333 MHz CPU will run stable when the FSB setting is correct.

Please refer the picture for JCLK1!|s location.

When motherboard has VIA SATA controller, it needs to turn on SATA RAID ROM for using as first boot device. Otherwise, Windows cannot recognize the SATA HDD properly and have problem to boot-up. Please refer the picture for enable RAID ROM in BIOS.

If BIOS update is not successful or failed, system cannot boot properly and Boot Blocker function will be activated. Users can recover the BIOS back when following error message appear on the screen. If motherboard has on-board VGA, the screen might go black. Then it needs to use AGP or PCI VGA card on the motherboard to see the screen output. BIOS ROM checksum error Detecting floppy drive A media!K INSERT SYSTEM DISK AND PRESS ENTER To recover the BIOS, follow the procedure for backup. 1.Make a bootable DOS floppy disk then copy AWDFLASH.exe utility and correct BIOS file. 2.Insert the disk into floppy drive and press Enter key. 3.System will boot-up to DOS prompt. 4.Type Awdflash xxxxxxx.bf /sn/py/r in DOS prompt. 5.System will update the BIOS automatically and restart. 6.After restart, BIOS has been recovered and system will work properly. Note: xxxxxxx.bf will be the BIOS file name. It can also support the BIOS format other then BF/BS extention. For example to use P4TSE's BIOS for recovering. Type Awdflash TSE0319.BF /sn/py/r in DOS prompt. For example to use U8668D's BIOS for recovering. Type Awdflash U8668R23.DDR /sn/py/r in DOS prompt.

The default IDE detect time on iDEQ200S might be too short for some of the IDE hard drive or CDROM. The IDE detect time can set longer to help detect the IDE devices. To set the IDE detect time longer, please follow these steps. 1. Press Delete key go to CMOS during system boot-up. 2. Go to Advanced BIOS Features. 3. Set the Delay for HDD to 5 seconds. 4. Save and Exit the CMOS setting.

If your system does not have screen output after over-clock. This might be caused by the CPU!|s Front-Side -Bus (FSB) over the chipset!|s limitation. You can restore the BIOS default setting by clear the CMOS setting. Once the CMOS goes back to default setting, the System will able to boot-up properly. Following show the procedure how to Clear the CMOS Setting: 1. Turn off the system and remove AC power cord from the power supply. 2. Set JCMOS1 to Pin 2-3. 3. Wait for 10 seconds. 4. Set JCMOS1 back to Pin 1-2. 5. Connect AC power cord back to power supply and power on the system.
