The Asus Motherboard M2NPV-VM utilises the mcp55 chip set...

It can utilise the nv_sata driver and hence run in native sata mode rather
than in pata emulation mode.

The following allowed migration to the nv_sata driver.

Install nv_72 with disks not mirrored.

edit the script

changing it to the following
 diff nv nv1

< DRIVER_ALIASES='"pci10de,37f" "pci10de,55" "pci10de,54"'

> DRIVER_ALIASES='"pci10de,266" "pci10de,267" "pci10de,37f" "pci10de,55" "pci10de,54"'

make sure your boot-path has no apostrophes (') to define the settings in /boot/solaris/bootenv.rc

run the script
make sure the /etc/driver_aliases contains the nv_sata entries
and reboot
