www.BlackViper.com: CUV4X-D Problems and FAQ Page 2

As you should already know, this mother board has the capability of "dual CPU's" or Symmetric Multi Processing (SMP). Furthermore, no OS uses these capabilities other than Windows NT/2000 and Linux SMP kernals (to avoid the hate mail, I am sure there is more than this...but it is beyond this article) Thus, you will see NO difference in performance while running Win95/98/Me with this board and 2 CPU's installed! I have not installed a flavor of Linux on this board to be able to test compatibility with such systems, but I have used it with WinMe and Win2k!

Configuration One:

Stability, I found was fine. Never once did I have to reboot due to glitches or plain old fruitiness associated with Windows in general. What I did find was the Sound Blaster Live! card gave me massive problems (discussed later on in the "SBLIVE!" part of this article). What I did tend to feel was that the hard drive access was slower than "normal." After cruising through VIA's web site, I found that that was a "known" issue and Win2k SP2 would fix the UDMA/ATA100 problems. Another known issue was the "IDE Large file copying corruption" bug. I transfer large amounts of information around on my home network and never encountered this particular problem...

Configuration Two:

This also worked just fine for me. I did not experience any unusual lock ups, nor problems that I previously was tortured with using SMP and SBLIVE! After letting the boards settle for a few weeks and allow the manufactures to "discover" compatibility problems, I decided to give it another shot in the last few days...

Configuration Three:

This configuration, I have so far found, has no major problems...except what will be discussed in later sections. The "UDMA/ATA100" accessing problems seem to have been fixed, either with the BIOS update, the SP2 update, or the v4.32 4in1 update...which one it is, I have no real clue...but it works...why over analyze? :)
Using the SBLive WDM default Win2k drivers did not cause the SBLive problem to resurface...but once again, more information in the next section.

UPDATE: July 28, 2001 @ 9:54 PM PST

After installing WinXP RC1 on Configuration Three, I checked up on the previous SBLive! problems and it seems that there is no cause for alarm...The SBLive works just fine and, so far, I have not found any problems with it! Stay tuned...
I did seem to have troubles with my USB IntelliMouse Optical. It was tracking VERY erratically upon first install/boot up and I could not find any settings that would change that fact (as in the BIOS setting of "Legacy USB support," etc). but after returning it to the PS/2 port, everything works fine...

UPDATE: August 7, 2001 @ 5:44 PM PST

After installing WinXP RC2 on Configuration Three, I checked up on the previous USB IntelliMouse Optical. I just plugged it in to the USB port as I had done before and it works wonderfully. Looks as if Microsoft DOES fix stuff... :)

UPDATE: August 16, 2001 @ 3:39 AM PST

After searching high and low for a solution to the crashing of Windows XP on Configuration Three, I found out that if you keep "Video BIOS Shadowed" to ENABLED, it will STOP all of the crashes with "nt4disp.dll." It was crashing at least twice per day at the desktop. I also knew it was not a nVidia problem cause it crept into another one of my computers using the "810" as the graphics basis.
