yes, this was meant as an example
also mind, that the last printf with "\rOK...." is meant to overwrite the hint message, so nobody should ever notice that message. i`m just unsure if this is a good approach. i have found two occurences in linux kernel, where drivers do something similar.

yes, but how to detect if we got stuck forever inside that bios probe ?
i assume that`s hard to do, so that`s why i`m printing that hint "into the future", to be overwritten on successful return.

sure! will add that if there is some positive feedback and someone finds this patch useful.
