Hello. I am using an Acer Aspire TC-780A, it has an Intel Core
i5-7400 CPU, and is currently running BIOS RO2-B2 by AMI. The machine
has UEFI support, and according to `dmidecode`, the ROM is 6MB.

Not all flash regions are freely accessible by flashrom. This is most likely
due to an active ME. Please see https://flashrom.org/ME for details.
At least some flash regions are read protected. You have to use a flash
layout and include only accessible regions. For write operations, you'll
additionally need the --noverify-all switch. See manpage for more details.

=== Additional info ===
- Specs sheet: The best I could find is this unofficial one for the
780, not the 780A, but they're extremely similar machines as far as I
can tell. https://www.manua.ls/acer/aspire-tc-780/specifications
- Other relevant info: None really. If anyone would like me to try
something, feel free. This machine is running Arch Linux, so anything
that can run on Linux should work fine. I also have an EFI Shell
binary installed, **and the official BIOS flashing EFI script from
Acer**.
