I have previously backed up the bios and am attempting to erase it, and am left in an "unknown" state. My desire is to successfully execute the erase. I am constrained from physically disassembling the mx204 router to confirm the board and chip.
Multiple flash chip definitions match the detected chip(s): "MX25L12805D", "MX25L12833F", "MX25L12835F/MX25L12873F", "MX25L12845E/MX25L12865E", "MX25L12850F" I tried doing wp-status on all of them, and all responded "Cannot read SECURITY: unsupported by chip" except for "MX25L12850F" which responded: Protection range: start=0x00000000 length=0x00000000 (none) Protection mode: disabled node:/var/tmp/fw/x86_64-linux-gnu/sbin# ./flashrom -p internal:laptop=this_is_not_a_laptop -c "MX25L12850F" --ifd -i bios --erase -noverify-all --force -V flashrom 1.4.0-devel on Linux 5.2.60-rt15-LTS19 (x86_64) flashrom is free software, get the source code at https://flashrom.org flashrom was built with GCC 12.2.0, little endian Command line (11 args): ./flashrom -p internal:laptop=this_is_not_a_laptop -c MX25L12850F --ifd -i bios --erase -noverify-all --force -V Initializing internal programmer /sys/class/mtd/mtd0 does not exist No coreboot table found.

We could not detect this for sure because your vendor has not set up the SMBIOS tables correctly. Some internal buses have been disabled for safety reasons. You can enforce using all buses by adding -p internal:laptop=this_is_not_a_laptop to the command line, but please read the following warning if you are not sure. Laptops, notebooks and netbooks are difficult to support and we recommend to use the vendor flashing utility. The embedded controller (EC) in these machines often interacts badly with flashing. See the manpage and https://flashrom.org/Laptops for details. If flash is shared with the EC, erase is guaranteed to brick your laptop and write may brick your laptop. Read and probe may irritate your EC and cause fan failure, backlight failure and sudden poweroff. You have been warned. ======================================================================== The following protocols are supported: FWH, SPI.
