How do your clear CMOS?

Clearing CMOS

Clearing CMOS will reset your Bios to the default.  The CMOS RAM on your mainboard is powered by the battery to the left of PCI slots 5 & 6.  I know of two ways to clear CMOS.  One is quick and one takes a bit longer.  CMOS is controlled by JBAT1.

JBAT1

JBAT1 has two settings:

Pins 1-2: Keep Data
Pins 2-3: Clear Data

Quick reset:

1. Turn off your PC.
2. Unplug the power cord; remove case cover.
3. Touch the power supply (to clear body static)
4. Remove jumper from JBAT1 (Pins 1-2)
5. Place jumper on JBAT1 Pins 2-3.
6. Wait 30 seconds
7. Place jumper back on JBAT1 Pins 1-2.
8. Replace case cover and power cord.
9. Boot and reset Bios settings as appropriate.  

Longer reset

1. Turn off your PC.
2. Unplug the power cord; remove case cover.
3. Touch the power supply (to clear body static)
4. Remove CMOS battery from mainboard.
5. Cycle power supply (on/off)
6. Remove jumper from JBAT1 (Pins 1-2)
7. Place jumper on JBAT1 Pins 2-3.
8. Wait at least 10 minutes.
9. Place jumper back on JBAT1 Pins 1-2.
10. Replace CMOS battery on mainboard.
11. Replace case cover and power cord.
12. Boot and reset Bios settings as appropriate. 

Step 5 above may be a key to resetting your Bios if you've had problems doing so.  Even when your system is off it still has some residual power floating around the board.  Cycling the power button will rid your system of that power.

How do you flash your Bios?
My KT4V-L originally came with Bios v1.2.  I've since flashed them four times now to v1.6, v1.7, 1.8, then 1.9.

Go here for the latest Bios file:  MSI KT4V driver support

The hard drive my OS is on is configured to NTFS (not FAT32)....so I flash my bios via my CD-rom.  You MUST have a CD-RW.  Here's how I flashed to v1.8:

1.  Download file from site above.
2.  Unzip file into folder of choice.
3.  Copy the Bios file (a6712vms.180) and the flash program file (amifl827.exe) onto a CD-R.
4.  Restart your PC using a Windows Boot Disk which provides CD drive support.

If you need a boot disk, go here:  Bootdisk.com

5.  Once in DOS mode locate the two files on your CD-rom and at the DOS prompt type:

E:/amifl827.exe a6712vms.180

6.  Hit enter.
7.  Follow programs prompts; exit when complete.
8.  Reboot and watch the top of your screen to see if the flash took.
9.  Enter Bios and reset settings as necessary. 

Does it work?  Yes.  Did I have any problems?  No.

If you don't have a CD-RW and would like a CD-R with these two files on it you can email here.  

Flash your Bios at your own risk!

How do I fix IDE CRC errors?
The KT4V has some known IDE CRC errors.  MSI has addressed this problem with Bios update v1.7.  The Bios updates can be found here.  

Along the same lines, Microsoft addresses DMA Mode for ATA/ATAPI Devices in Windows XP here.

I guess I've been lucky.  I've never experienced CRC errors on my PC....and I do alot of CD-R burning too.

How do I install the VIA USB2.0 Patch (Under WinXP+SP1)?
1.  Download the file from here.
2.  Unzip the file in your folder of choice.
3.  Go to "Device Manager" and under "Devices By Type" look for "Universal Serial Bus Controllers".
4.  Highlight "Standard Enhance PCI to USB Host Controller" and select "Properties".
5.  Select the "Driver" tab.
6.  Select "Update Driver".
7.  Select "Install from a List or Specific Location".....point it to the files you unzipped.
8.  Hit the "Next" and "Finished" keys until complete.
9.  Reboot your PC.
10.  If the update took correctly Device Manager will have changed from "Standard Enhance PCI to USB Host Controller" to "VIA USB2.0 Enhance Host Controller".

Why doesn't my CPU run at full speed?
The default CPU FSB Clock speed is 100.  Therefore you must enter Bios and increase it to the appropriate speed which is 133 for most of you....166 for the rest.  Just take your CPU's FSB speed....divide it in two and that is what you use.
AMD Processor FSB Set
XP 1700 1.47 GHz 266 133
XP 1800 1.53 GHz 266 133
XP 1900 1.60 GHz 266 133
XP 2000 1.66 GHz 266 133
XP 2100 1.73 GHz 266 133
XP 2200 1.80 GHz 266 133
XP 2400 2.00 GHz 266 133
XP 2600 2.13 GHz 266 133
XP 2700 2.17 GHz 333 166
XP 2800 2.25 GHz 333 166

How do I overclock my KT4VL?
I am NOT into overclocking....I've stated this on my main page.  Yet, many folks are asking me how to overclock their CPU.  Maybe some time in the future I'll try it.

Here are some overclocking resources found on the net:

I just assembled my KT4VL and I cannot get it to run properly.  What did I do wrong?
Updated: 12 Jul 2008

Oh yeah.  The joy of building your own PC and then the disappointment of seeing that it doesn't work properly.

First and foremost you MUST do a clean install of your Operating System.  You CANNOT just plug
in your old harddrive (HDD) from another system/mainboard and expect it to boot and work properly....

As far as Operating Systems (OS) go....for the casual PC user WIN XP is best, then WIN ME, then WIN 98SE.  You folks who use another OS sure don't need my help :)

Make a list of your PC devices (this will come in handy for troubleshooting).

OS:
Case:
Fan1:
Fan2:
Fan3:
Fan4:
Fan5:
Fan6:
CPU: 
DDR1:
DDR2:
DDR3:
FDD1:
IDE-1Master:
IDE-1Slave:
IDE-2 Master:
IDE-2 Slave:
AGP:
PCI-1:
PCI-2:
PCI-3:
PCI-4:
PCI-5:
PCI-6:
CNR:

I flashed my Bios with the wrong ROM.  What can I do?
If your floppy drive still seeks on power up and then stops after a short period of time, you may have a chance to recover by using your floppy drive.

Go here for the latest Bios file:  MSI KT4V driver support

For a MS-6712 KT4V follow this example:

Copy the BIOS update file (a6712vms.180) onto a diskette.

Rename the "a6712vms.180" file to "AMIBOOT.ROM" reboot then press and hold Ctrl-Home to force update.

The AMI boot-block BIOS will look for the AMIBOOT.ROM file.  The floppy doesn't need to be bootable.  You will see the PC read the floppy, after about 4 minutes you will hear 4 beeps, this means the transfer is done.  Now remove the diskette from the PC and restart the PC normally.

If this method fails you will need to replace your Bios chip.  Go here:

Is my Power Supply Unit (PSU) adequate?
Ensuring your Power Supply Unit (PSU) provides enough power to your system is paramount to a smooth running system.  If your PSU is inadequate you will experience degraded system performance.....or perhaps your PC or a single component will not run at all....

Minimum requirements are:

+3.3V 24A or above
+5V 30A or above
+12V 16A or above

 Check the label on your power supply.  It looks like this:

ATX 350W Power Supply Label

Based upon my minimum requirements posted above, you can see that my +3.3V is average, +5V is above specs, and +12V is a bit below specs....it all comes down to how many Amps you have left over.

If you want to positively know if your power supply is adequate you have to add up the numbers of all devices your PSU is plugged into.....and hope they do not exceed your power supply limits....  For example....a typical Lite-On 32x CD-rom drive requires 5V-1.0A. and 12V-1.2A.  Using my  power supply above it would leave me with:  5V-34A and 12V-10.8A. 

The KT4V-L Mainboard itself draws quite a bit of power from the PSU.  The fan connectors, CPU socket, AGP, PCI and DDR slots, etc.  I have yet to figure out how many Amps each draws....

How can I make my KT4V board run cooler?
The following five items will affect system cooling:
  • Lower your room temperature.  If your room is hotter than 80f it WILL affect your PC.
  • Add fans for greater air flow.  Suck it in and blow it out.
  • Tidy up your cables.  The air inside your case will not move if it is blocked by cables.
  • Bios V1.8.  Enable "CPU Halt Command Detection".  This just cycles the CPU on and off thereby reducing CPU heat by less usage.  
  • Bios V1.9.  MSI tweaked the CPU temp detection.  This bios upgrade should lower your temps at least 4c.
