[ros-diffs] [fireball] 37409: - Target device to mount may not have VPB, the driver should get the VPB passed in parameters. - Set target device's VPB to this value. This should not really be done, however our driver heavily depends on target device having this VPB. I don't see any side effects. - With these changes, Windows 2003 is able to boot up to desktop and cleanly shutdown using this driver.

Log:
- Target device to mount may not have VPB, the driver should get the VPB passed in
parameters.
- Set target device's VPB to this value. This should not really be done, however our
driver heavily depends on target device having this VPB. I don't see any side effects.
- With these changes, Windows 2003 is able to boot up to desktop and cleanly shutdown
using this driver.
