 1 long - 2 short     No video card found
                      (Apply only to baseboards with no onboard 
                       video controller.)

 1 long - 3 short     No Monitor connected present
                      (Apply only to baseboards with no onboard 
                       video controller.)

 1 long - x short     Video related failure
                      (Other video beep codes may exist and are tied to 
                      specific video BIOS implementations. Contact the 
                      vendor for details.)

    2                  Parity Error      
                       (Parity error in the base memory (the first 64 KB 
                       block) of memory.)

                       Timer 1 is not functioning.)

    5                  Processor Error         
                       (The CPU generated an error.)

    6                  8042 - Gate A20 Failure
                       (Cannot switch to protected mode.)
    
    7                  Processor Exception     
                       (The CPU on the CPU Card generated an Interrupt
                        Error on exception interrupt.)

    8                  Display Memory Read/Write Error
                       (The system video adapter is either missing or its 
                       memory is faulty. This is not a fatal error.)

    9                  ROM Checksum Error      
                       (The ROM checksum value does not match the value 
                        encoded in WinBIOS.)

   10                  CMOS Shutdown Register Read/Write Error
                       (The shutdown register for CMOS RAM has failed.)
                                                      
   11                  Cache Memory Bad / Do Not Enable Cache
                       (The cache memory test failed. Cache memory is 
                       disabled. Do not press <Ctrl> <Alt> <Shift> <+> 
                       to enable cache memory.)

WinBIOS Screen Error Messages


 - 8042 GATE-A20 ERROR     
   Gate A20 on the keyboard controller (8042) is not working.

 - ADDRESS LINE SHORT!     
   Error in the address decoding circuitry.

 - DRIVE C: FAILURE        
   No response from hard disk drive C:.

 - CACHE MEMORY BAD,DO NOT ENABLE CACHE!
   Cache memory is defective.

 - CH-2 TIMER ERROR        
   An AT system has two timers. There is an error in timer2.

 - CMOS BATTERY STATE LOW  
   CMOS RAM is powered by a battery. The battery power is low. 
   Replace the battery.

 - CMOS CHECKSUM FAILURE   
   CMOS RAM checksum is different than the previous value. 
   Run WINBIOS Setup.
   
 - CMOS SYSTEM OPTIONS NOT SET
   The values stored in CMOS RAM have ben destroyed. 
   Run WINBIOS Setup.
   
 - CMOS DISPLAY TYPE MISMATCH
   The video type in CMOS RAM does not match the type detected. 
   Run WINBIOS Setup.

 - CMOS MEMORY SIZE MISMATCH
   The amount of memory found by WINBIOS is different than the 
   amount in CMOS RAM. Run WINBIOS Setup.

   No response from hard disk drive D:.
                        
 - DISKETTE BOOT FAILURE 
   The boot diskette in drive A: cannot be used to  boot the system. 
   Use another boot diskette and follow the screen instructions.

 - DISPLAY  SWITCH NOT PROPER 
   Some systems require a video switch be set to either color or
