- The firmware is burned into ROM on the device and can't be updated by the user. So if an update is required the user needs to either live with whatever faults the original firmware had, or return the device and get a new one. And of course, for a returned device, the vendor might be able to desolder the ROM chip and replace it with a new one with the newer firmware and resell it. Or maybe it's really flash, but only the vendor has the tools to flash the firmware. This all is apparently fine by the FSF.
- The firmware is stored on flash on the device and can be updated by the user. This is apparently BAD according to the FSF, Boo Hiss!
- The firmware is stored on disk, and is loaded to the device by the device driver as part of initializing the device. Also very BAD and makes hair grow out of your palms.
