@lispi314 It's not software, as you cannot reprogram a ROM chip, but it's no so hard as hardware that you cannot change it - it's firm.

It's not soft at all - the only way to change it is to replace it, with either a compatible ROM or PROM or EEPROM chip (in the last case you've changed what was firmware into software), although you don't need to go as far as replacing all the hardware or even doing any a hardware modification (i.e. desoldering something).


The Talos II BMC uses an EEPROM to store software - it's just inconvenient to flash it; https://wiki.raptorcs.com/wiki/Debricking_the_BMC
