CMOS Storage Locations
The PCM-VDX-2-512’s BIOS configuration is stored in three (3) locations:
(1) CMOS RAM (nonvolatile if battery backed)
(2) FLASH PROM (nonvolatile storage for factory defaults)
(3) Internal Flash (for custom settings)
Saving the CMOS Configuration
The Real-Time Clock and the CMOS RAM settings can be maintained by an optional battery when the board is powered
off. When the external battery is used, simply disconnect the battery from
J8
for 20 seconds. When an optional on-board
battery is used, it can be enabled or disabled at
JP7
. A battery is always required to maintain time and date functions when
the board is powered off.
