STOP: 0x0000004C (parameter, parameter, parameter, parameter) FATAL_UNHANDLED_HARD_ERROR
This is a Windows 2000 Executive character-mode STOP message. This indicates a fatal hard error (STATUS error) occurred before the hard error handler was available. There are several reasons why this error might occur: a Registry hive file could not be loaded because it is either corrupted or missing; Winlogon or Windows unexpectedly did not start; or a driver or system DLL is corrupted.
If this is the first time you have booted after installing new hardware, remove the hardware and boot again. Check the Microsoft Hardware Compatibility List to verify that the hardware and its drivers are compatible with Windows 2000. For information about the hardware, contact the supplier. If you are installing Windows 2000 for the first time, check the Windows 2000 system requirements, including the amount of RAM and disk space required to load the operating system. Also, check the Hardware Compatibility List to verify that the system can run Windows 2000. If Windows 2000 is loaded and no new hardware has been installed, reboot with recovery options set to create a dump file. If the message continues to appear, select the Last Known Good option when you reboot. If there is no Last Known Good configuration, try using the Emergency Repair Disk. If you do not have an Emergency Repair Disk, contact your technical support group.
