PXI規(guī)范允許PXI機箱和系統(tǒng)模塊。為協(xié)助系統(tǒng)集成商、制造商PXI機箱和系統(tǒng)模塊必須記錄其產品。最低文件要求包含在.ini文件，由ASCII文本組成。系統(tǒng)集成商，配置實用程序和設備驅動程序可以使用這些.ini文件。
機箱的功能文檔包含在底盤。由機箱制造商提供的ini文件。信息在該文件中，與有關系統(tǒng)控制器的信息相結合，以：創(chuàng)建一個名為pxisys的系統(tǒng)初始化文件。ini（PXI系統(tǒng)初始化）。NI PXI-8105使用MAX生成pxisys.ini來自機箱的文件。ini文件。設備驅動程序和其他實用軟件讀取PXISY。ini文件到獲取系統(tǒng)信息。有關初始化的詳細信息，請參閱文件夾，
升級RAM您可以通過以下方式更改NI PXI-8105上安裝的RAM數量：升級SO-DIMM。
要升級RAM，請從PXI機箱中卸下NI PXI-8105。到優(yōu)化內存容量和系統(tǒng)性能，使用相同的大小
并且在兩個模塊插槽中的每一個中加速存儲器模塊。使用每個插槽中支持不同大小的模塊，但系統(tǒng)性能
將比使用兩個匹配的模塊慢。然而，兩者不匹配模塊將比使用單個模塊產生更好的性能。

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
at ni.com/support.
Note Your system hot key is <F4>. To access the hard drive-based recovery tool, press and
hold <F4> when video first appears during the boot process.
