Q    My Celeron II CPU is not recognized correctly by the Bios what should I do?

A    If your Bios is prior to Version 1006, you will need to manually configure dip switches.

Q    I cant find jumper settings in the manual or the Asus web site. What are jumper settings for my Celeron II CPU?

A    Celeron CPU use a CPU Bus Frequency of 66 MHz. So, take the frequency of your chip and divide by 66, the result is         the correct multiplier. For example for a Celeron 533MHz: 533/ 66 = 8X. If the multiplier is larger than 8X use 8X.  If          you are planning on overclocking you will definitely want to flash to the latest Bios. This will allow Bios recognition of your          chip, and control over CPU voltage settings

Q    I looked on the Asus site but all I can find is Bios Ver 1005. Where can I get the latest Bios?

A    Try Asus Germany: ftp://ftp.asuscom.de/pub/ASUSCOM/BIOS/Socket_370/INTEL_Chipset/i440BX/CUBX/

Q    I looked on the Asus site, and can't find the CMD PCI UDMA 66 Driver. Where can I get the latest driver?

A    Try here : ftp://ftp.asuscom.de/pub/ASUSCOM/TREIBER/CONTROLLER/IDE/CMD/

        or e-mail CMD support: pc-support@cmd.com 

Q    When I set my CPU voltage at anything over 1.65 the computer wont boot. What should I do?

A    Don't set your CPU voltage at anything over 1.65 : )                                                                                                         (BTW most Celeron II do NOT require more voltage than this to overclock. I am running my 560 @ 850 MHz with 1.6V)

Q    When I reset my voltage and frequency sometimes it does not take.

A    "The weird thing about the CUBX, which I discovered after endless scavenging through various hardware forums, is that it sets    the new Vcore voltage after it receives the ATA-66 drive data while loading into Windows. Therefore, to successfully increase your voltage and overclock, it requires two step process. First, while running your processor at its default unoverclocked state, increase the Vcore to your desired setting. Let your system boot into Windows. The next step is to restart from Windows, enter BIOS and select the overclocked speed that you want. You may want to check the BIOS hardware monitor to see the Vcore voltage." - Thanks to Sean for this tip. I have duplicated this issue, and found the above technique works without actually going all the way into windows. Safe mode command prompt is fine. - Dave

Q    I am having trouble booting or running with the ATA 66 Controller

A    1) Boot from the intel Controller and install the CMD drivers

        2) To boot from the ATA controller you need to set *THREE* things inthe BIOS:

1. Enable on-board ATA controller chip. (Advanced page) >Chip Configuration -  Scroll for the LAST ITEM
2. Choose ATA 66 at the option 'Boot SCSI/ATA66 First' (i believe this is on PCI configuration page)
3. Put ATA 66 controller at first place in the boot sequence (Boot page).
Now Boot Windows
device mgr > primary/ secondary CMD
Ultra DMA bus master IDE > properties
Select ultra dma mode 4 - Yes, it will warn you that they no longer take responsibilty for the integrity of your data. (make sure you are using the correct ATA66cable!)
