MSI K8N Neo2 Platinum bios 1.52 beta won't boot

[ScottFern]

I just flashed to the 1.52 beta bios and now my machine won't even boot past the bios screen. I removed the soundcard and reset the cmos jumper and still the computer turns on posts for about 4 seconds and then turns itself off.

What do I do now to get the older bios back in there and working again!?!? Anyone who can help let me know this is an EMERGENCY now!!!

Unplug power. Take out CMOS battery, leave PC alone for an hour.

I'd be surprised if it did not boot, especially if you got to the end when it said "flash successful."
