IA260 WinCE User’s Manual Introduction
Firmware Build Versions
There are two ways to determine the version of your IA260-CE computer’s firmware. You will
need to know the firmware version to identify which features your IA260-CE supports.

y Log on to the web-based management system (described in a later chapter) to view the system
information.
Memory and File Systems
The SDRAM has 128 MB of memory space, of which 112 MB is allocated for the main memory
in which the operating system and user applications run. The kernel image occupies the rest of the
space.
The IA260-CE’s internal file system controls access to the ROM, and also provides file storage in
the object store, which is in the RAM. The ROM file system provides persistent storage for
applications and the data used by the applications, even when the main power supply is lost. It
integrates the read-only files that are stored in Flash ROM with the read/write files of both an
application and a user. In the IA260-CE computer, a child directory named “NORFlash” under the
root indicates the ROM storage of the flash memory is 12 MB.
The root directory is a 12 MB RAM file system. It can be used for storing temporary files for your
applications. However, do not place persistent files or applications in the root directory, because
they will be wiped out when the system is shut down. Instead, place them in the “NORFlash”
directory.
The file systems for storage devices connected through the USB port and CompactFlash are placed
in the root of the internal file system. If you intend to use these devices to port data between your
PC and the IA260-CE computer, format them using the FAT file system on your PC.
Hive-based Registry (not RAM-based)
The registry for the IA260-CE is a hive-based registry instead of a RAM-based registry. The
hive-based registry stores registry data in files, or hives, which can be kept on any file system.
This removes the need for performing backup and restore on power off.
Inserting a CompactFlash Card
The IA260-CE is equipped with a CompactFlash slot of type II that supports cards of both types I
and II. A mass storage card is considered to be a standard attachment to the computer. Thus, when
an empty mass storage card is inserted into the slot, the computer automatically formats it to the
FAT system. This process takes a few minutes to complete. When a mass storage card is inserted,
the IA260-CE creates a directory named “HardDisk” under the root directory and the newly
created directory serves as a link to the storage. The IA260-CE does not support PNP (plug and
play) and hot swap for CompactFlash storage devices. Users must switch off the power and then
insert the CompactFlash storage device in the slot. When the power is switched on again, the
IA260-CE will detect the CompactFlash storage device. Be sure to shut off the power before
removing the CompactFlash storage device.
Some CompactFlash storage disks are not compatible with the IA260-CE. You can try using other
CompactFlash storage devices, or use “System Manager” to disable ultra DMA.
