It's also not obvious (at least not to a dumb user like me) that "ignore HPA limit" is equivalent to "preserving the Host Protected Area" as the commit commit says. After reading the wiki page on HPA it looks like the actual meaning is to "make the HPA visible to the OS"? > + Format: { "0" | "1" } > + 0 -- keep BIOS limits > + 1 -- ignore limits, using full disk (default) Hmm. This looks weird. Is "BIOS limits" a synonym for "HPA limit"? Same goes for the MODULE_PARM_DESC. Cheers, FJP
