*******THE VERDICT : Chaintech Zenith VNF4 = BFG Nforce4 Ultra

[TimeKeeper]

Cut the story short.

I flashed my BFG NF4 with Chaintech's version 4 BIOS and it works!
Both bios has same model number and BIOS string.
(reason I chose version 4 because it was dated April when BFG has yet to release its first board. Also, people claimed version 4 to be the best OC version for Chaintech)

Comparison:
1. both Version 4 or 719Bios does NOT push my CPU any higer. (289X9@1.525v)
2. both Version 4 and 719BIOS share exact BIOS menu, selection, and setting.
3. Version 4 has BIOS bug, where UNUSED IDE channel can't be turn off.
(when you choose "NONE", next time you boot up, it will scan that channel again)
4. 719BIOS bug on BIOS Saving issue, if you OC too much, it will reset EVERYTHING itself.
5. performance are similar. But I don't think Version 4 support AMD X2 cpu.

Here is quick memory test on both board. (HT:3X, HT Bandwidth: 16dual, initial DDR on 133Mhz@ 3-3-3-8, CPU: 289FSB, DDR running: 385Mhz)

old news. I flashed my VNF4 Ultra to the BFG v5.0 bios months ago. I think it was determined that these are the same boards sometime in January. There are zillions of threads on this on AT, HardOCP, PCPER, etc.

BFG products = rebadged Chaintech with prettier HSF
