Hello. I need help because I deleted my BIOS on Acer with Windows 10. I wanted to update my BIOS, I found a program, I opened it, then my screen stuck on its last image, and when I start it up it powers on and beeps for a long time, then it beeps again. The keyboard, no signs, screen no signs.

    Here is what I found, because indeed it isn’t obvious.

    BIOS Recovery for X5300 and 3300

    AMIBIOS8 supports a "flash recovery" mode, which can be used to update a BIOS from the boot block.
    This is used to update a BIOS image without needing to boot into an operating system. What follows is the
    process the user must follow to flash the BIOS ROM.
    1. Prepare a disk-on-key (DOK) and keep it handy.
    (1). Connect the USB storage device to a USB port on your computer.
    (2). Save AMIBoot.ROM to the USB storage device.
    (3). After saving the file, unplug the USB storage device.
    2. Connect the USB storage device containing the DOK to a USB port on the system.
    3. Press the power button to start the system, then press Ctrl + Home.
    The system initializes the BIOS recovery process. The failed BIOS code will be restored from the DOK.
    4. Once the process is complete, the system will reboot.

    For you, I think it’s from step "2" by using on the USB drive the BIOS update file (the correct one), because I suspect you would have used a BIOS file that is not the correct one...

    But in any case, it seems feasible..

    Could you share the brand and model of your motherboard..??

    For that, you need to open the PC and read what is indicated on the motherboard..

      DOK: Disk On Key, basically, as explained above, a disk format file on a USB flash drive.

      I did some reading; the DOK is indeed a USB key around 8GB or 4GB that is formatted in FAT32 ("SD Card Formatter" https://www.clubic.com/telecharger-fiche443607-sd-memory-card-formatter.html#modalbox) and containing nothing other than your P01-B3.ROM file..??

      I looked at this file, it seems meant to be run from Windows by a .BAT file, which surprises me.

      that BIOS_Acer_P01.B3_A_A file is 1174 KB

      The ZIP file contains three folders for this BIOS recharge via three paths...

      There is one for Windows, another for DOS and the other directly towards the BIOS ROM

      The one you have, P01.B3.ROM, is meant to act directly on the BIOS ROM, so it’s indeed the right one... except that it shouldn’t be run from Windows... I would even say you should disconnect your hard drive while you do this...

      The procedure is partly the same as my POST 14... like this:

      a). Connect the storage device to a USB port on the motherboard (rear)

      b). Press the power button to start the system, then press Ctrl + Home. (Home is the key with the arrow pointing up-left) it’s quick.

      The system initializes the BIOS recovery process. The faulty BIOS code will be restored from the USB. you have to be patient.

      4. Once the process is finished, the system will reboot.

      After this reboot, you should be able to access the BIOS and see its menus. That would be a good sign...

      I think your Windows-based manipulation may have infected your Windows system...

      Moreover, given the age of this PC and its hard drive, there may also be defects on the disk.

      All of this is unfavorable to proper operation and you would be the victim of several combined errors...

      So try to do that, see what happens... I admit that the possibilities will eventually run out...

      The "Home" key is next to the numeric keypad, the one with the arrow pointing up and tilted 45° to the left...

      So, in the second after power-on, you need to press and hold the "Ctrl" key, then tap the "Home" key 4 to 5 times...

      If that works, the PC restarts after 'burning' the BIOS memory... you should let it restart; wait a bit and observe... the screen will stay black, I suppose, if the disk is indeed unplugged... and it will display a brief message in English... that would be a victory over the BIOS

      Next, you should restart the PC and go into the BIOS menus... the key is F2 I think or "Del" in the second after power-on...

      You take a screenshot... and paste it here.

      So see you tomorrow.. don't have nightmares

      The system initializes the BIOS recovery process. The failed BIOS code will be restored from the DOK.

      4. Once the process is completed, the system will restart.

    Hello,

    Don’t cry just yet... Normally on PCs there is a BIOS double in the same memory, it is by default, but it allows you to recover your PC...

    But the minimum is to know exactly which Acer model it is..?? EXACTLY

    For this action, we don’t care about the Windows version.

    and it must be written in your manual.

      It's an Acer Aspire X3300 and how to do it?

    Hi

    Only high-end motherboards have a dual BIOS, and even then it’s more of a manufacturer specialty (Gigabyte) and that tendency has been fading in recent years (having two BIOSes is very expensive and complex to implement)

    If it’s a failed flash, there’s not much to do...

    when you start the PC, do you have access to the BIOS by pressing the keyboard key that allows you to enter it?

      Hello,

      Well yes, it’s enough that we have the old BIOS file on a USB drive and that the PC is set to boot from the USB, but that raises a lot of ifs...

        Well no! If the BIOS is corrupted, the PC cannot boot from the USB drive (or from any other medium) since that setting is precisely in the BIOS...

        Well no! If the BIOS is corrupted, the PC cannot boot

        Indeed,

        There are "BIOS recovery" procedures but they are generally on retail motherboards, and not all of them... and not 100% guaranteed.

        On a low-end Acer PC, without hope.

        However, since the motherboard beeps, all may not be dead; it is possible that the flash succeeded but altered so many default settings that the PC is no longer able to boot, which is why I’m asking whether it could or could not enter the BIOS.

    In my opinion, the BIOS recovery is dead; the only option is to return it to ACER's warranty service, which is quite expensive, and in any case more than another motherboard which, given the PC’s age, will be used.

      Hi Bazfile

      I also think it’s poorly started.

      When the BIOS is potentially recoverable, it’s already very complicated to do; it’s a bit of navigating by sight or improvisation, so explaining such a manipulation remotely to someone who doesn’t have the basics…

        Yes, difficult remotely; some motherboards have a BIOS flash button that allows updating the BIOS via a USB drive even if the BIOS does not boot anymore, which apparently is not the case for this older motherboard.

        So for me it’s a non-issue, it remains only the warranty service or the motherboard replacement.

    Here is the ACER X3300 Manual https://manualsdump.com/en/manuals/acer-x3300-x5300/160918/33 With a DA078L-AM3 BIOS recovery motherboard, Page 25 Note, on page 68, a drawing showing the "Clear CMOS" at JBIOS1 It must be moved 15 seconds to position 2-3 for RAZ and then returned to position 1-2 to continue normally.. - -Since the CCM modification, there is no longer a presentable layout.
