For people having POST problems (long IDE detection) on Cold Boot with K8N Neo 2

Question

It's been 2 weeks that I'm looking for the root of this particular problem.
I've found today how to get rid of it. Try this if you haven't already :
In BIOS root screen, activate the hidden settings (Press SHIFT+F2 and ALT+F3 rapidly)
Then go to the Cell Menu and disable NV/ATI Speedup feature.
Save your settings, turn off your comp.
Restart and check with cold boots

I have a worse variation of this problem (but also the startup IDE freezing that fixes with Alt-Ctl-Del), that I discovered while trying to boot from an ME CD or from a WinME Floppy boot disc when and only when I tell it to load support for CD-Rom going into DOS.  It freezes when it gets just past detecting the IDE, requiring a cold boot reset.
If I boot off the WinME CD or a floppy boot disk, and don't choose CD-ROM support I can get to the A: drive with RAM C drive to be able to flash the BIOS (which I did up to 1.3, after which I reset the CMOS jumper).  The problem persists with the new MOBO 1.3 BIOS.
I made sure the IDE-2 ribbon was connected properly, and even tried changing the jumper from master to cable select on the Plextor DVD burner....still locks up when I boot to DOS with CD Rom support enabled.
My next step was to disconnect the IDE cable from the Plextor so the drive was not the issue, and it still freezes if I choose CD Support from Boot disk.
I next removed the CMOS battery (which btw, will require you to call MS to reactivate XP), checked the voltage with a battery tester, replaced it, cleared CMOS jumper again, use mostly default BIOS settings except disabled SATA, and the same damn problem.  
My friend, Triple6 in this same thread has the identical setup except different RAM, different nVidia 6800 Ultra Video card  and he does not have the same bootup  issue.  We checked the same BIOS settings.
I'm beginning to wonder if I have a bad MOBO that won't allow me to boot off a floppy with CD-ROM enabled.  Very Strange!
