Software Differences
The Intel E3800 Series cpuModules have several software-related differences, which are summarized
below. Complete information about these CME34BT features can be found in Chapter 4,
.
aDIO
While the 16-pin aDIO connector is pin-for-pin compatible with previous generations of RTD cpuModules
(such as the Intel Core 2 Duo series), the hardware is slightly different, and requires that writes ands reads
to/from the aDIO ports happen no more than once per millisecond. Migrating legacy software to the E3800
Series that utilizes RTD’s Advanced Digital I/O may require that you add this delay prior to all reads and
writes.
UEFI Shell
Previous generations of RTD cpuModules contained a Failsafe Boot ROM image, which permitted the
cpuModule to boot to a DOS prompt even when no disk drives were connected to the system. The RTD
E3800 Series cpuModules provide a similar prompt, called the Unified Extensible Firmware Interface
(UEFI) Shell, which provides an enviroment to execute simple commands when no bootable devices are
connected to the system.
