ASUS P5N-E 0401 Bios problem

[alarum]

I just flashed to the 0401 bios. I can't enter the BIOS anymore?. The system posts and I enter the bios and the screen just stays black?.

I tryed to downgrade to 0202 and 0307 and it will not allow me.

I guess I am waiting for a new bios now to fix this..err.. The system seems to be working other wise..ie windows boots work fine.. I just can no longer enter the bios..

Any help would be appreciated..Cheers.

Alarum,

I posted my findings over there, but I'll sum it up for you.
0401 killed my rig too! Couldn't enter BIOS after countless CMOS clears, etc...

Advice:
Pop out all your RAM, put just ONE stick in the B-1 slot (yellow, furthest from processor)
(I was able to get into BIOS just from that alone, but I would recommend the following)
After one stick of RAM is in place, remove ALL unneccessary hardware from board, strip down to bare minimum. If you're really in a crunch, just remember, you don't need a HDD to get to BIOS, and if you get into BIOS you will eventually find something that works (my mantra... it keeps me going).

Then pop battery, clear CMOS


I had to make the following adjustments:
*Ram WILL NOT WORK in black slots now, only yellow
*Had to lax RAM timings to 5-5-5-12 2T (This board likes manual timings!)
SLI Ready RAM EPP setting to 0%
standard voltages/clocks
Also be sure to check the boot device priority in BIOS, mine changed after update and favored my IDE devices over the SATA ones.
Also had to remove and reinstall Audio hardware & drivers with new release version

Cheers

Finally I've found someone with the same problem!

I flashed to 0401 and have the same problems as you. I too was only able to get into the bios with ram in the yellow slots. I've cleared the CMOS multiple times, all to no avail. I've also tried reflashing the bios. I can boot into windows and linux, but they lockup soon after. Memtest spits out loads of errors, which I don't really understand. I don't know if my actually memory is screwed, or if it is more the motherboard. Since this happened right after a bios upgrade, I'm betting on the mobo. ASUS suggested I RMA it, but if there is a simpler fix, I would obviously much prefer that. Numble, are you just going to continue with your current setup and wait for a new bios revision?
