IMITATION
Most Windows operating systems can be purchased in 32-bit or 64-bit versions, depending on the
processor of the target system on which it will be executing. Due to the way that this board maps
memory, 32-bit OS versions will not be able to identify or use more then 2 GB of RAM. The 64-
bit Windows versions, and Linux kernels using a HIGHMEM64 configuration, will correctly
identify and use memory sizes larger then 2 GB.

The VersaLogic VL-MF7 Series modules provide 1 or 2 GB of RAM plus 8 GB of flash storage.
These modules function only in socket J13. The solid state drive (SSD) can function as a
bootable SATA drive or secondary storage device without claiming either of the SATA channels
at connectors J1 or J7.

A jumper may be installed into V1[2-3] to erase the contents of the CMOS RAM and the Real-
Time Clock. When clearing CMOS RAM:
1.
Power off the VL-EBX-37.
2.
Remove the jumper from V1[1-2], install it on V1[2-3] and leave it for four seconds.
3.
Move the jumper back to V1[1-2].
