POST Error Messages Numeric Codes and Text Messages (Continued) Code/Message Probable Cause Recommended Action 1999-Master Boot Record has Changed. The current MBR does not match the previously saved copy of the MBR. Use extreme caution. The MBR may have been updated due to normal disk maintenance activities (disk manager, fdisk, or format). Replacing the previously saved MBR in such situations can cause data loss. If you are certain the MBR change is unintentional and undesired (e.g. due to a virus), then run Computer Setup and restore the previously saved MBR copy. Otherwise, run Computer Setup and either disable MBR security or save the MBR of the current bootable disk. 2000-Master Boot Record Hard Drive has Changed. The current bootable hard drive is not the same as the one that was present when MBR Security was enabled. Run Computer Setup and either disable MBR security or save the MBR of the current bootable disk. Invalid Electronic Serial Number. Electronic serial number has become corrupted. 1. Run Computer Setup. If Setup already has data in the field or will not allow the serial number to be entered, download from www.hp.com and run SP5572.EXE (SNZERO.EXE). 2. Run Computer Setup and try to enter serial number under Security, System ID, then save changes. ECC Multiple Bit Error Detected in Memory Module.
