flashrom told me to send you this log alongside the output of lspci, so
here you go ;)
$ sudo flashrom -p internal -r curie-backup.rom

Found chipset "AMD FP4".
Enabling flash write... FCH device found but SMBus revision 0x59 does
not match known values. Please report this to flashrom(a)flashrom.org and
include this log and the output of lspci -nnvx, thanks!.
Could not determine chipset generation.PROBLEMS, continuing anyway
You may be running flashrom on an unknown laptop. 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
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
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.
No EEPROM/flash device found.
Note: flashrom can never write if the flash chip isn't found
