Chapter 2 Installation and Configuration© National Instruments Corporation 2-15 NI PXIe-8105 User Manualproducts. PXI Express devices must provide a driver and .ini file foridentification. These files are provided as part of the PXI Platform Servicessoftware included with your controller. The minimum documentationrequirements for PXI-1 are contained in .ini files, which consist of ASCIItext. System integrators, configuration utilities, and device drivers can usethese .ini files.The capability documentation for a PXI-1 chassis is contained in achassis.ini file provided by the chassis manufacturer. The informationin this file is combined with information about the system controller tocreate a single PXI-1 system initialization file called pxisys.ini(PXI System Initialization). The NI PXIe-8105 uses MAX to generate thepxisys.ini file from the chassis.ini file.Device drivers and other utility software read the pxiesys.ini andpxisys.ini file to obtain system information. For detailed informationabout initialization files, refer to the PXI specification at www.pxisa.org.Upgrading RAMYou can change the amount of installed RAM on the NI PXIe-8105 byupgrading the SO-DIMMs.To upgrade the RAM, remove the NI PXIe-8105 from the PXI Expresschassis. To optimize both memory capacity and system performance, usethe 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 systemperformance will be slower than using two matched modules. However,two mismatched modules will result in better performance than using asingle module.National Instruments offers the following types of SO-DIMMs for use withthe NI PXIe-8105 controller.• PC2-5300 512 MB, 64 MB × 64, CL 5, 1.18 in. max(NI part number 779302-512)• PC2-5300 1 GB, 128 MB × 64, CL 5, 1.18 in. max(NI part number 779302-1024)Note National Instruments has tested and verified that the DDR2 SO-DIMMs we sellwork with the NI PXIe-8105. We recommend you purchase your DDR2 SO-DIMMmodules from National Instruments. Other off-the-shelf DDR2 SO-DIMM modulesare not guaranteed to work properly.
