Dell BIOS System Messages:
MessagePossible CauseCorrective Action
nnnn Cache RAM Passednnnn KB of system cache RAM has been successfully tested
nnnn Extended RAM Passednnnn KB of extended RAM has been tested
nnnn Shadow RAM Passednnnn KB of shadow RAM has been successfully tested
nnnn System RAM Passednnnn KB of system RAM has been successfully tested
CD-ROM drive IdentifiedThe systems automatic drive type detection feature has identified the CD-ROM drive
Diskette drive A error; Diskette drive B ErrorDrive A or B is present but has failed the BIOS POSTEnsure that the drive is installed correctly in the chassis and detected correctly in the system setup
Entering SetupThe system is starting the system setup program
Extended RAM Failed at offset: nnnnExtended memory is not working correctly or is not configured correctly at offset: nnnnIF you receive this message after making changes in the system setup program, enter the program and restore the original value(s)
Failing bits: nnnnnnnn is a map of the bits at RAM address that failed the memory test. Each 1 in the map indicates a failed bitIf you receive this message after making changes in the system setup program, enter the program and restore the original value(s)
Fixed Disk n Failure; Fixed Disk Controller FailureThe hard drive specified by n is not working or not configured correctlyEnsure that the drive is installed correctly in the chassis and defined coracle in the system setup program
Fixed Disk n IdentifiedThe system's automatic drive type detection feature has identified the hard disk drive(s)
Incorrect Drive x type - Run SetupDiskette drive x is not correctly identified in the system setup programEnsure that the drive is defined correctly in the system setup program
Invalid NVRAM media typeThe system is having a problem accessing NVRAM (CMOS)Set the configuration jumper to Maintenance mode and restart the system to return all settings to their defaults
Invalid system configuration dataThe system configuration information is the system setup program is incorrect, or the battery charge may be lowEnter the system setup program and verify the system configuration, then restart the system
Keyboard controller errorThe keyboard controller failed it's testIf you receive this message after making changes in the system setup program, enter the program and restore the original value(s)
Keyboard errorThe keyboard is not working correctlyThe keyboard or system board may need to be replaced
Keyboard error nnThe BIOS has detected a stuck key represented by scan code nnMake sure nothing is resting on the keyboard. If a key appears to be stuck, carefully pry it up. if the problem persists, you may need to replace the keyboard
Mouse initializedThe system's mouse has been found and initialized
Operating system not foundThe operating system cannot be located on drive A or drive CEnter the system setup program and confirm that drive A or drive C is properly identified
Parity check 1 nnnnA parity error has been detected on the system bus. The BIOS attempts to locate the address and display it nnnn. If it cannot locate the address, it displays ???? insteadIf you receive this message after making changes in the setup program, enter the program and restore the original values(s)
Parity check 2 nnnnA parity error has been detected on the I/O bus. The BIOS attempts to locate the address and display it nnnn. If it cannot locate the address, it displays ???? insteadIf you receive this message after making changes in the setup program, enter the program and restore the original values(s)
Press <F1> to resume, <F2> to SetupThis message is displayed after a recoverable error messagePress <F1> to start the boot routine or <F2> to enter the system setup program and change any settings
Press <Del> to enter SETUPOptional message displayed during POSTId desired, press <Del> to enter the system setup program
Previous boot incomplete - Default configuration usedAfter a unsuccessful boot, POST loads default valuesThere may be incorrect values or incorrect settings in the system setup program. Run the system setup program and attempt to restore the incorrect settings. If the message reappears, set the configuration jumper to Maintenance mode and restart the system to return all settings to their defaults
Real time clock errorThe RTC has failed the BIOS testIf you receive this message after making changes in the setup program, enter the program and restore the original values(s)
Resource allocation conflict on motherboardThe system cannot configure all system board devices without a resource conflictRun the system setup program and try to resolve any obvious resource conflicts. If the message reappears, set the configuration jumper to Maintenance mode and restart the system to return all settings to their defaults
Shadow RAM failed at offset: nnnnShadow RAM has failed at offset nnnn in the 64KB block in which the error was detectedIf you receive this message after making changes in the setup program, enter the program and restore the original values(s)
System battery is dead - Replace and run SETUPThe CMOS clock battery indicator shows the battery is deadReplace the battery and run the system setup program to reconfigure the system
System BIOS shadowedThe system BIOS has been copied to shadow RAM
System cache error - cache disabledRAM cache failed the BIOS test. The BIOS has disabled the cacheIf you receive this message after making changes in the system setup program, enter the program and restore the original settings
System CMOS checksum bad - run SETUPSystem CMOS has been corrupted or modified incorrectly, perhaps by an application program that changes data stored in CMOSRun the system setup program and reconfigure the system by either reverting to the default values or by making your own selections
System RAM failed at offset: nnnnSystem RAM failed at offset nnnn in the 64KB block in which the error was detectedIf you receive this message after making changes in the setup program, enter the program and restore the original values(s)
System timer errorThe timer test failedIf you receive this message after making changes in the setup program, enter the program and restore the original values(s)
UMB Upper limit segment address: nnnnDisplays the address nnnn of the upper limit of the UMB, indicating released segments of the BIOS which may be reclaimed by a virtual memory manager
Video BIOS shadowedThe video BIOS has been successfully copied to shadow RAM
