Yeah S- Can the whole thing and 90% of all users of Linux?

Give up on IDE, it is too broken.
You should get away with paralelising USB and SCSI scan.
Perhaps you can speed boot up with initrd+modules, pos

Yes, it is called probing.
You issue a command to the channel and hope that something res

Linux already boots fairly quickly, but there seems to be one
straightforward way to speed it up a little more: pipelining.
The idea is to split the initialization of drivers into two routines.
This is only useful for drivers that reset hardware and then wait a
while before continuing. My though
