They have a 8MB flash part - which is divided into a 4MB "temporary" side and a 4MB "permanent" side. - - The temporary side is the flashside used for the normal operation and the - permanent side is used as a backup if the temporary should ever fail. - - Therefore it is important that the permanent flash side is not changed so - that if ever required the original firmware can be restored. - - SLOF usually warns or in most cases does not easily allow to overwrite the - permanent side. - - !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! - !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! - ! ! - !
