SeaBIOS and ATA spinup

[Kevin O'Connor]

Hi,

Latest SeaBIOS git should now handle the case where SeaBIOS can't find
drives because it runs before the drives are ready.

The code tries to wait for not-BSY.  However, if the ide bus appears
to be "floating", then it will stop waiting.

Myles - I know you were working around this on your board.  Can you
test if the code in git works for you?

Thanks,
-Kevin

I haven't had that problem for a while.  I thought you'd already fixed it :)

Thanks,

It turns out that the option ROM for my VGA card was taking long
enough that it allowed the drives to spin up.  Once I changed cards it
exposed the problem again.  Latest SeaBIOS does fix it.

Too many variables to keep track of :(

Thanks,
