[Coco] NitrOS9 L2 CoCo 3 question: Display settings/modifications

[Bill Pierce]

Tormod, I find that odd, unless you're referring to loading system modules. If I try to load a program with a bad CRC, it will usually fail. Usually "Error 205 - Illegal Module Header", "Error 232 - Incorrect Module CRC" or "Error 236 - Bad Module Header".
I know OS9Boot files with bad CRCs will load and "attempt" to execute, but bad CRCs usually mean something is corrupt and the boot (or the bad module in some cases) will fail.
Ident & Id will check module headers (even in merged files like OS9Boot) and report bad CRCs.
