Andrew and Michel,
Is our patch valid only for VP3 and not for VP1/VP2?
Second, I have discovered the hardware that ide interfaces go only
as fast as the slowest device. There may be a timing error due to
device or conflicts or something of this nature.
What do you say?
This may be a case of individual device tuning of the chipset.
