System CMOS checksum

System CMOS has been corrupted or modified incorrectly,

 

bad - Default

perhaps by an application program that changes data stored

 

configuration use

in CMOS. The BIOS installed Default Setup Values. If you do

 

 

not want these values, enter Setup and enter your own

contact your dealer.

0280

Previous boot incomplete -

Previous POST did not complete successfully. POST loads

 

Default configuration used

default values and offers to run Setup. If the failure was

 

 

caused by incorrect values and they are not corrected, the

 

 

next boot will likely fail. On systems with control of wait

 

 

states, improper Setup settings can also terminate POST and

 

 

cause this error on the next boot. Run Setup and verify that

 

 

the wait-state configuration is correct. This error is cleared

 

 

the next time the system is booted.

System cache error - Cache

RAM cache failed and BIOS disabled the cache. On older

 

disabled

boards, check the cache jumpers. You may have to replace the

 

 

cache. See your dealer. A disabled cache slows system

 

 

performance considerably.
