Installation du BIOS EEE PC 900HD

Solved

Hello, I have an Asus Eee PC 900HD running Windows XP. It was working fine until I encountered a message at startup; I ended up on the BIOS installation page. I don’t know how I got there, and I don’t know how to exit. I tried to download the BIOS for the PC and ended up downloading the BIOS for the Eee PC 900 (I don’t know if it’s the same). Anyway, I put the file on a USB stick, renamed it "900HD.ROM" as the PC requests when inserting a USB drive... but the PC does not detect the BIOS. I researched and found out that the BIOS file needs to be on a USB stick formatted in FAT16 (the stick must be less than 4 GB to format in FAT16). I don’t know how to format a USB stick in FAT16.

To summarize, could someone guide me on:
. how to exit the BIOS download mode
. if the Eee PC 900 is the same as the Eee PC 900HD, and if the BIOS I downloaded is the correct one (anyway, that’s the only one available for download)
. how to format a USB stick to FAT16
Thanks in advance...

    Hi,
    If the PC only allows you to flash at startup, that's not a good sign, as it means the BIOS is self-detecting as corrupted or unable to boot...

    The CR2032 battery may be dead; check it.

    Normally, BIOS after 2001 (after the release of XP) can use a FAT32 partition; FAT16 was necessary before. (assuming the PC was purchased with XP).

    I'm not sure the BIOS of the 900 matches the 900HD. There's a good chance it doesn't.
    And I remind you that flashing with the wrong BIOS can cause complete PC failure without any affordable repair option for anyone.
    So basically, don't flash the BIOS until you're sure of its compatibility. Sometimes BIOS will prevent you from flashing with the wrong file, but sometimes not, so be very careful.

      Hello and thank you for your response. Firstly, most of the BIOS for Asus Eee PCs have been removed from download, which is not very cool. On a site where someone shows how to flash the Eee PCs, they say that the Eee PC 900 does not detect the BIOS, which seems to be my case. When I insert a USB stick with the file 900HD.ROM, it tells me: Checking for usb device,
      Usb device found,
      Reading file "900HD.Rom"
      File 900HD.ROM not found on usb device.

      It cannot find the file...

      A silly thing, when you name the file 900HD.rom, the .rom refers to the extension, not the end of the file name?

      Windows hides file extensions by default, so if you haven't changed it, your file is actually named 900HD.rom.rom (if the base extension is .rom)

      But I remind you that if you flash with the wrong BIOS, you risk a complete brick.

    So the BIOS version file 0702 as indicated
    this one https://dlcdnets.asus.com/pub/ASUS/EeePC/EeePC900HD/900HD-ASUS-0702.zip
    And you do as the man in the video (format and rename the file)

      For the photo, it's without which would be interesting.
      Finally, update the BIOS, since it's going in this direction
      We'll see later if needed.

      I do the same thing, except for the formatting; I need to format in FAT then...

      In fact, I can't update the BIOS, I'm doing exactly the same thing but it doesn't work.
