 I'm pretty sure this has come up before and there's a workaround that
 can be copied from the other bootblocks. But that's just a dim memory
 from wading through gnats and I don't really know anything about it...

 Easiest solution is to probe and see whether or not A20 is enabled.
 If it is, don't mess with it.
 Otherwise we need to consider new BIOS calls, which are problematic.

 This cannot be the correct fix.
 The delay() calls will be there because they are needed - at least for
 some systems.

 It looks as though delay() isn't calibrated (or is using some unsupported
 BIOS call), so some alternate implemention is needed.
