Before i am beggining to explain my issue this issue has began 2-3 weeks ago and then it started to bother me every single day
I've build many pc, never encountered this annoy issue before. When I cold power the pc, it cycles debug code and then it resets and get stuck at B2 (Legacy Option ROM Initialization). At this point I must turn off the pc by pressing the power button, then turn on pc by pressing power button again and it will boot into windows. So basically every time I want to use my computer I need 4 resets, what is up with that?

Before I made this post I did look into B2 code error however those people had this problem couldn't boot at all, I can boot just annoying 4 resets to get into windows, so I'm not sure if this is by design or something is going wrong. I can sort of live with this issue as my pc is still usable and I'm posting it from it, but I never had this much trouble to turn on a pc before.


Things iv'e tried so far:
1.I tried with another gtx 980 same issue.
2.Moved the gpu to another pcie slot and same issue.
3.Updated to the latest bios version same issue.
4.Bought a new memory kit same issue.
5.Clear CMOS same issue.
6.Reseat CPU same issue.
7.tried to play with UEFI settings in the bios same issue.
8.tried different bios same issue.

the only thing left so far is the motherboard do you think my motherboard is causing the issue?should i RMA it?
thank you

Your SSD, how long have you had it and have you updated the firmware/software for it? There is an issue with that model that has only recently been addressed by Samsung.

hmmm i have it about a year or so?and samsung magician says that i am using the latest firmware DXM06B0Q

These are the latest packages: 840 EVO : EXT0CB6Q, 840 EVO mSATA : EXT42B6Q

Firmware for the latest was released on October 24th IIRC.

Try that and see if it helps.

I don't have the evo version i have the 840 pro version the url you linked shows the latest firmware of my ssd is DXM06B0Q which i already have installed.that firmware update came months ago....

O.K.

so any other suggestions?

Been pondering on it. ROM (Read Only Memory) related issues are usually BIOS-type chips. These can be updated as you know. Sometimes they can become corrupt as well. Think about any upgrades, updates, anything like that you may have done lately, or should have done but haven't gotten to. Is that 980 card new? Does the manufacturer have their own proprietary BIOS? Do they have any updates on their site? Just thinking at the keyboard here.......

The upgrades only was the gpu that's it..but like i said i also tried friends gpu and same problem...so i really don't know what to do i checked i am using the latest gpu bios version...this error driving me nuts

From what I've been reading there seems to be a number of folks with Legacy ROM Initialization problems. And no firm solutions. The latest ASUS BIOS is 4901 dated 18June14; if you have that one you have the latest.

Do you have the latest drivers for your USB ports?

You put a friend's 980 in to check, but did you put your older video card back in and if so, did it work?

Have you tried setting everything in your BIOS to 'default' and if so, were there any improvements?

This could be a defective MB, hard to say. Your BIOS may allow you to disable legacy firmware baked into the board; mine doesn't, but it's something to check.

i am using the latest 4901 bios.
Yes i am using the latest USB ports,i don't have anymore the old gpu because i sold it.like i said earlier i cleared bios means it did reset everything to defaults and same issue.
i am not sure if you can disable legacy firmware or what ever i tried to play with every single settings and same problem...

I've run out of ideas. Maybe someone else can chime in with a solution.

No solution but the exact same problem for me. I get the "b2" error code, the "vga led" lights up red and there's nothing happing on the screen. This is on a brand new computer that is store build.
I only get this error sometimes, about every fifth time I start up, but it seems like it's becoming more and more frequent.

The graphics card is indeed sagging down a bit although everything is still brand new. I hope this is not the case, but the error code "b2" might get more frequent as time and gravity takes it's toll. Sagging with age issue perhaps, where have I heard of that before...
