Both the intent and the effect of reserve_bios_regions() is simple: reserve the range from the apparent BIOS start (suitably filtered) through 1MB and, if the EBDA start address is sensible, extend that reservation downward to cover the EBDA as well. The code is overcomplicated, though, and contains head-scratchers like: if (ebda_start < BIOS_START_MIN) ebda_start = BIOS_START_MAX; That snipped is trying to say "if ebda_start < BIOS_START_MIN, ignore it". Simplify it: reorder the code so that it makes sense. This should have no functional effect under any circumstances.
