FYI: To those getting no video at all during POST on K8N Neo2 Plat

Question

I've been racking my brain all day/night fighting my new K8N Neo2 Platinum system. I first put together a minimal system with just memory, CPU/cooler, and AGP card and powered it up to make sure it would work. Sure enough I saw the Platinum POST screen and I went into the BIOS.
I figure all is good so I turn off the system and install the rest of the components.Like so many others I powered back up to the disheartening screen of nothingness. The D-Bracket showed all 4 LEDs green so I was baffled as to the problem. I tried various forms of restart with the same result. With a sigh I began reverting my system back to the original bare bones set up. Same result...black screen. I tried various CMOS resets after reading everything I could find. New result: black screen but POST would always get stuck with D-Bracket indicating "Initializing Floppy Drive Controller".
After trying various memory configurations, various CMOS resets, various AGP graphics cards, and many other things for several hours to no avail I finally got out an ancient PCI graphics card and was finally able to get video and enter the BIOS. I selected Load Fail-Safe Defaults and made sure to select AGP for the Primary Graphic's Adapter setting. I swapped the PCI card out and the AGP card back in. Still no video on the AGP card. I put the PCI card and AGP card in together and rebooted again. PCI card has video, AGP card does not.
I still don't have my problems solved but I at least wanted to let people who are getting no video on their AGP graphics card know that they may be able to get video on a PCI graphics card. As a side effect, for whatever reason, it appears that I get fully through the POST again and the D-Bracket lights up all the LEDs.
Hope this helps someone out there who is frustrated like I am and maybe someone can figure out what's wrong with the AGP graphics.
The BIOS version is currently W7025NMS V1.3 092404 15:57:09...I'm going to work on updating that next and see if that fixed anything.
Here's my system if it would work:
MSI K8N Neo2 Platinum
AMD Athlon 64 3500+ 90nm
Gigabyte 3D Cooler-ULTRA GT
OCZ 520W PowerStream
OCZ 512MB DDR400 PC3200 EL Platinum Rev. 2 (4 sticks)
BFG nVideo GeForce 6800 Ultra
I made the following substitutions to test:
OCZ DDR400 PC3200 EL Platinum Rev. 2 (1 stick in various slots, 2 sticks in various slots in single and dual channel mode)
Corsair 512MB Value Select DDR400 PC3200 (1 stick in DIMM 1 slot)
Radeon 9700 Pro (old AGP card -- didn't work any better than BFG card)
Some old PCI card -- not even sure what it is (allowed me to see what was going on!)

Nope. Cable is definately not on upside down! =)
I get the same behavior on both floppy drives I've tried. The light only comes on when it tries to access it and it reacts as though I've put in a bad floppy. Thing is the floppy works on several computers and works on one of the floppy drives I used with this system, only while it was connected to another machine.
I was able to update the bios to v1.4 without using a floppy by making a bootable CD and flashing from there. Still no go. I think at this point I'm ready to concede that I do in fact have a motherboard that has gone south. I've tried every combination of option I can think of in the BIOS but the AGP and Floppy Controller both appear to be fubar.
Still, the one good thing that came out of all this is that I found out how to make bootable CDs. I'm sure to use that little trick over and over and that may make it so I don't really need these pesky floppy drives anymore at all! I'll make a post on this so we'll soon all be floppy free! =)
