Hardware & Technical Need some reassuring advice...BIOS.

Hi all.

Her good self has commandeered the main PC to continue in her studies. This I have no problem with, I also has meant I could build another PC (tight budget)

I have the exact same motherboard model in both builds, one is running a Haswell CPU (works fine) the new one has a Haswell refresh CPU.

The Asus H81M-Plus needs a bios update to work with the new CPU.

I have a spare chip on its way, but i am a little impatient.

My plan is this evening to remove the socketed DIL8 (dual in line 8 pin IC) BIOS chip from the "new" build, swap it into the working build, should be ok as it s on an older BIOS, update the chip, drop it back into the new board and boot (hopefully)

Anyone see any potential problems doing this?
I understand about static, I work in the electronics industry.
The alternative is move the CPUs - not ideally what I want to do!

Thoughts?

Thanks in advance.

It should be fine to do this - no different from buying a new bios chip which I've done a few times in the past - just make sure you put the chip in exactly the same way obviously.

Really? I kinda have this long messy job planed out for that!

Fan off, clean thermal paste, replace paste, refit CPU, fit fan, boot, update, repeat so CPUs are in the right machine (new one is faster)

Ok that option is on the table then...

Yup, identifier notch/dot pin 1 etc.

Thanks, I'll see if I can dismantle both PCs for a bit tonight then!

Thinking about this,

I intend on removing the "good" bios chip from the working PC and keeping this as it is to one side, just in case the other chip is stuffed or i muck it up, that way I can leave the working machine as it is until the new chip arrives.

Tried a few things last night.

For simplicity I'll call the main working PC "Tower", and the new build "Cube".

Removed bios chip from tower and inserted Cube's bios chip and flashed to latest bios (bios 2109)

Installed into Cube.

Tested both PCs, Tower booted, Cube did sweet FA.

Flashed Bios in Tower, swapped CPU.

Cube booted, tower did not.

I am now beginning to think my brand spanking new G3250 CPU is DOA.

But I have also spotted on Asus' website a BIOS updater tool...looks like a windows application based bios flashing exe, so this is my final port of call before a CPU RMA goes in.
At least the motherboard works.

I have solved the issue. As mentioned Asus do a windows based BIOS update tool, this for some reason works. The BIOS I have had to use is an older version (Ver.2001) but this seems to have fixed it.
I am not sure if there are two issues at play here, doing a massive jump in BIOS versioning rel 501 to 2109... unlikely but I have worked in software where this kind of jump breaks things, pretty sure BIOS doesn't work like that. Or it was using the windows based tool actually properly updated the BIOS.

Anyway CMDRs, I'll be back out in the Void when all the drivers are found and working!

Thanks for the help up to this point!
