have been changed. Be extremely careful during write operations such as copying, saving, or formatting.
Data or programs can be overwritten if you select an incorrect drive.
General error messages appear if a problem or conict is found by an application program, the operating
system, or both. For an explanation of these messages, refer to the information supplied with that software
package.
Before replacing a FRU, ensure that the latest level of BIOS is installed on the system. A down-level BIOS
might cause false errors and unnecessary replacement of the system board.
