    Can't update my BIOS


    Hey everybody. Lately, I've been trying to fix my high DPC latency issues and I was about to update my BIOS to see if that would fix the problem. Unfortunately, I'm having some trouble getting the update to run. I'll provide the instructions I'm trying to follow below. I can get all the way to booting off the USB, but all my computer shows me is a blinking cursor and nothing happens. What is it I'm doing wrong? Any help is much appreciated.

    How is your usbstick formatted Fat 32 or NFTS?
    Use Fat 32 and check create a DOS bootable disk.
    And if possible use no usb3 port.

    Thanks for the tip. Didn't realize you had to make it bootable first. I have since downloaded "Rufus" and re-formatted it correctly. The damn instructions didn't say anything about that. Friggin' Acer.

    Anyway, I manged to get into the DOS folder off my USB and run "BIOS_DOS.bat" and things didn't pan out too well. The flash started to run and a few seconds later I was met with an error message. I'll provide said error below. Any idea what to do next guys?

    Error Message: "ERROR: ROM FILE ROMID is not compatible with existing BIOS ROMID"

    Current BIOS version: "P11-A2 2014-06-24"

    Damn it, nevermind. I just realized the BIOS update I'm trying to run is for Linux. Can't believe I missed that. Man, am I an idiot.

    Thanks anyway, everybody.

    If Acer made any changes to the bios, it should have still updated when you chose to boot with USB.

    If it was meant to be ran in Linux, you would have to mount the stick, while running a Linux Live DVD.

    This is not a BIOS issue anyway! I do not EVER recommend updating the BIOS unless the update specifically addresses a problem I am having. And those are very rare. Typically, BIOS updates just add support for new components (like new CPUs or RAM) that came out after the motherboard left the factory.

    ALWAYS, before updating a BIOS, read the change logs to see what the new BIOS update is for. And only update if it applies to you. The BIOS code does not suddenly go bad. It is EXTREMENLY RARE for a BIOS to become corrupt. The code is in "firmware" so it cannot become corrupt like a file on your disk. At worse, the CMOS information (which is user changes to the defaults set in the BIOS firmware) may become corrupt (as happens when the CMOS battery dies) but that only requires a reset of the CMOS information, not a flash of the BIOS firmware device.

    Your latency issues really are not that bad. This is a bad one. What symptoms are you trying to correct?

    Yeah, I agree. The BIOS was never the issue here.

    As a matter of fact, I believe my APU was the culprit. I recently installed a new GPU to replace my motherboard's built in APU and that seems to have solved my DPC issue. My latency measurements are MUCH lower now and I'm no longer hearing crackling, nor am I experiencing any freezing video.

    Anyway, thanks for the reply. It's much appreciated.

    No problem. At least you have a better card. The prices are still too high for my blood, for the studio quality 4k/uhd cards.
