It is probably not possible to replace your machine's firmware, and if you try you will almost certainly brick it.

Instead, please tell us why you would need or want to do that. Then, knowing what your problem is we will hopefully be able to help you find a solution.

Here's some information about Firmware and UEFI (Unified Extensible Firmware Interface).

https://ami.com/en/products/bios-uefi-firmware/
https://en.wikipedia.org/wiki/Unifie...ware_Interface

IF your looking for a Linux distribution to install on your netbook we will need the specifications of your machine, ie the make and model, single core? dual core? etc... to make a recommendation.

Did you want to replace or upgrade the BIOS?
Is your machine that old that you need to upgrade the BIOS?

IF so you must use the upgrade that the manufacturer created/built specifically for your exact make and model or your machine.

-::-The "wrong BIOS upgrade" will render your machine useless.-::-

reasons going off topic, but ... virtually all netbooks and tablets have sdxc readers. of those the vast majority does not allow booting from an sdxc card in the internal sdxc slot. netbooks and tablets are used on the road, in careless situations. a protrubing usb is quickly damaged, even when using those tiny thumb drives.

one way to get linux on chromebooks is seabios. so i figure if seabios or coreboot or another open source bios can be flashed to bios replacing the ami aptio and others, perhaps sd card booting from the internal sdxc reader can happen?

other reasons why boot sdxc? small/slow/cheap/unreliable internal storage, use the same system on different machines like netbook on the road and desktop at home, not taking the computer while traveling, multi booting with or without vm, etc. usb is great, sdxc that extra bit more convenient imo.

back to topic.

all chromebooks seem to be seabios flashable? so, how to get some open source bios replacing ami and the like on the rest so that sdxc booting is always possible?

An internet search with these arguments:
chromebook seabios
leads to these links:
https://www.maketecheasier.com/replace-chromebook-bios/
https://wiki.archlinux.org/index.php/Chrome_OS_devices

If you brick your machine, don't ask me for a refund

Also, I see on this page under SeaBIOS 1.9.0:
  • Initial support for booting from SD cards on real hardware
But I am not sure this works with all cards...

Good luck.
