Operating System Installation
The standard PC architecture used on the EPM-19 makes the installation and use of most of the
standard x86 processor-based operating systems relatively simple. The operating systems listed
on the
VersaLogic OS Compatibility Chart
use the standard installation procedures provided by
the maker of the OS. Special optimized hardware drivers for a particular operating system, or a
link to the drivers, are available at the
EPM-19 Product Support Web Page
Integrator’s Note:
The EPM-19 board supports only the 32-bit versions of Windows 7 and Windows Embedded
Standard 7 (WES7).
Note:
An operating system installed on a different type of computer is not guaranteed to work on the
EPM-19. This is referred to as a “foreign” installation. A hard disk that was used to boot a
different computer cannot necessarily be moved to the EPM-19 and expected to boot. Even
when porting an OS image from one revision of the EPM-19 to another, performance might fail
or be impaired. For the best results, perform a fresh installation of the operating system on
each system. This restriction does not apply if you are producing multiple identical systems.

ETTING
The ACPI version will need to be configured in the BIOS Setup utility as follows:
For Windows 7, set the ACPI version to V3.0. (Windows 7 requires version 2.0 or later.)
For Windows XP, set the ACPI version to V1.0 (Windows XP may function with version 2.0
but has not been fully tested.)
Integrator’s Note:
The EPM-19 board has been tested extensively with Windows 7 and seems to operate reliably
with the ACPI version set to V3.0. Other operating systems may have unique requirements for
setting the supported ACPI version. ACPI can be disabled in the BIOS Setup utility if it is not
required by the OS.

ONSIDERATIONS
When Windows XP is loaded on an mSATA card, it may be necessary to change the IDE
Operate Mode setting in the BIOS Setup utility from Legacy Mode to Native Mode for the
operating system to boot properly.

ONSIDERATIONS
If the microSD card is installed prior to board power-up, the board will expect to boot from the
microSD card because it appears as the Primary IDE device. If that is not the desired
configuration (that is, you want to boot from SATA or mSATA and use the microSD card as
storage device), you can fix this by modifying the GRUB root= boot argument from sdaX to
sdbX while the SD card is inserted. If Knoppix is installed to the SATA using Flash Install
utility instead of HD install, it won't use GRUB. Knoppix uses isolinux and is able to detect the
drive upon which Knoppix is installed.
