It can be in read-only memory, and in that case you can't upgrade it, if that's all that's available. More often what you'll have is some memory that's read-only and some that's read-write. The read-write memory contains the actual operational code for the camera and you can upgrade it. The read-only part contains the basic bootstrap loader and utility functions (like update the read-write memory) so they can't get messed up in an upgrade and you can always change the upgradeable firmware in the read-write part if something goes wrong. -- Thanks, DougF (KG4LMZ) -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net
