Re: HP 30b bricked when repurposing Message #3 Posted by Lode on 20 Aug 2011, 10:50 a.m., in response to message #2 by gene wright
For the flashing process, does the calculator require something valid in the ROM before flashing to let it work, or could the ROM chip contain complete random garbage, all zeros, a half-interrupted combination of old and new data, and would the flashing still work?
Is the processor of the calculator itself involved in the flashing, or is it only the cable and the ROM chip doing stuff?
If flashing the BIOS of a computer fails, you're screwed, since to be able to flash it you need to have a PC that's able to boot up as far as needed for flashing it. How does flashing a calculator compare to this?
Thanks.
