From 79d1d3311319f3390f540f547becaba9d957f84c Mon Sep 17 00:00:00 2001 From: "Jonathan A. Kollasch" Date: Fri, 3 Sep 2010 07:57:46 -0500 Subject: Improve ATA IDENTIFY word 64 contents. Fill in word 64 of IDENTIFY data to indicate support for PIO modes 3 and 4. This allows NetBSD guests to use UltraDMA modes instead of just PIO mode 0. Signed-off-by: Jonathan A.
