PXI规范允许PXI机箱和系统模块。为协助系统集成商、制造商PXI机箱和系统模块必须记录其产品。最低文件要求包含在.ini文件，由ASCII文本组成。系统集成商，配置实用程序和设备驱动程序可以使用这些.ini文件。
机箱的功能文档包含在底盘。由机箱制造商提供的ini文件。信息在该文件中，与有关系统控制器的信息相结合，以：创建一个名为pxisys的系统初始化文件。ini（PXI系统初始化）。NI PXI-8105使用MAX生成pxisys.ini来自机箱的文件。ini文件。设备驱动程序和其他实用软件读取PXISY。ini文件到获取系统信息。有关初始化的详细信息，请参阅文件夹，
升级RAM您可以通过以下方式更改NI PXI-8105上安装的RAM数量：升级SO-DIMM。
要升级RAM，请从PXI机箱中卸下NI PXI-8105。到优化内存容量和系统性能，使用相同的大小
并且在两个模块插槽中的每一个中加速存储器模块。使用每个插槽中支持不同大小的模块，但系统性能
将比使用两个匹配的模块慢。然而，两者不匹配模块将比使用单个模块产生更好的性能。
National Instruments提供以下类型的SO DIMM，
用于：NI PXI-8105控制器。
•PC2-5300 512 MB，64 MB×64，CL 5，1.18英寸。最大值
•PC2-5300 1 GB，128 MB×64，5级，1.18英寸。max Note National Instruments已经测试并验证了我们销售的DDR2 SO DIMM
使用NI PXI-8105。我们建议您购买DDR2 SO-DIMM
来自国家文书的模块。其他现成DDR2 SO-DIMM模块
NI PXI-8105控制器包括两种恢复原始状态的方法
硬盘的出厂条件。基于硬盘驱动器的恢复存储
在硬盘驱动器的单独部分进行工厂备份，使您能够：需其他介质即可恢复控制器。NI PXI-8105
控制器还附带了操作系统恢复CD，允许您重新安装
通过外部CD-ROM将操作系统安装到硬盘上。

The PXI specification allows many combinations of PXI chassis and
system modules. To assist system integrators, the manufacturers of
PXI chassis and system modules must document the capabilities of their
products. The minimum documentation requirements are contained in
.ini files, which consist of ASCII text. System integrators, configuration
utilities, and device drivers can use these .ini files.
The capability documentation for the chassis is contained in a
chassis.ini file provided by the chassis manufacturer. The information
in this file is combined with information about the system controller to
create a single system initialization file called pxisys.ini (PXI System
Initialization). The NI PXI-8105 uses MAX to generate the pxisys.ini
file from the chassis.ini file.
Device drivers and other utility software read the pxisys.ini file to
obtain system information. For detailed information about initialization
files,
Upgrading RAM
You can change the amount of installed RAM on the NI PXI-8105 by
upgrading the SO-DIMM.
To upgrade the RAM, remove the NI PXI-8105 from the PXI chassis. To
optimize both memory capacity and system performance, use the same size
and speed memory module in each of the two module slots. The use of
different size modules in each slot is supported, but system performance
will be slower than using two matched modules. However, two mismatched
modules will result in better performance than using a single module.
National Instruments offers the following types of SO-DIMMs for use with
the NI PXI-8105 controller.
• PC2-5300 512 MB, 64 MB × 64, CL 5, 1.18 in. max
• PC2-5300 1 GB, 128 MB × 64, CL 5, 1.18 in. max Note National Instruments has tested and verified that the DDR2 SO-DIMMs we sell
work with the NI PXI-8105. We recommend you purchase your DDR2 SO-DIMM
modules from National Instruments. Other off-the-shelf DDR2 SO-DIMM modules
are not guaranteed to work properly NI PXI-8105 controllers include two methods of restoring the original
factory condition of your hard drive. Hard drive-based recovery stores a
factory backup on a separate portion of your hard drive allowing you to
restore your controller without additional media. The NI PXI-8105
controller also ships with an OS Recovery CD that allows you to reinstall
your operating system onto your hard drive through an external CD-ROM.
For more information on these tools refer to KnowledgeBase 2ZKC02OK
