+ * Specific Register file and not PCI config space. Most BIOSes
+ * virtualize the PCI registers so the chip looks like a standard IDE
+ * controller. Unfortunately not all implementations get this right.
+ * In particular some have problems with unaligned accesses to the
+ * virtualized PCI registers. This driver always does full dword
+ * writes to work around the issue. Also, in case of a bad BIOS this
+ * driver can be loaded with the "msr=1" parameter which forces using
