Advantech PCA-6186 User Manual

Choose the “Standard CMOS Features” option from the “Initial Setup 
Screen” menu, and the screen below will be displayed. This menu allows 
users to configure system components such as date, time, hard disk drive, 
floppy drive, display, and memory. 

The CMOS RAM is powered by an onboard button cell battery.  
When BIOS CMOS Setup has been completed, CMOS RAM data is auto-
matically backed up to Flash ROM. If conditions in a harsh industrial 
enviroment cause a soft error, BIOS will recheck the data and automati-
cally restore the original data for booting.
