After you install a Windows Vista Service Pack on a computer that is running Windows Vista, you must restart the computer in order for the changes in hardware to take effect. However, SP2 introduces two new problems: 1. The HMC may remain in the System Configuration section of the Power Management window when the computer is restarted , causing error messages when you try to boot the computer. 2. If SP2 is the only update they have installed, SP2 may prevent dynamic memory operations on a partition as long as the SP2 devices driver is loaded. If the device driver is unloaded prior to the operation and then loaded again afterwards, adapter initialization may fail, leading to a BSOD (Blue Screen of Death). A Partition Shutdown / Activate sequence on the HMC may be needed to recover from this situation.
After you install Windows Vista on a computer, the device driver under the driver category "Display devices" may fail to install, and Windows Vista will notify you about this. However, if you transfer the driver to another computer, it will install correctly, and you will be able to use the display device. The driver is required for the HMC to function correctly.
After you install Windows Vista on a computer, laptop, or tablet, the location of the DRAM memory needs to be changed. Otherwise, when the Windows Vista Service Pack is enabled, it will fail to load driver components. Additionally, after the service pack was enabled, the DRAM memory did not route correctly and the laptop was no longer usable. In some cases, the DRAM memory needs to be switched to a different location in order to correct the routing problem, and to eliminate the spinner that is displayed when the computer is loading. This problem affects all Windows Vista operating system updates (including SP1). d2c66b5586
