Targa 2000 RTX Card<br />

To use a Targa 2000 RTX card with the system’s Sound Blaster 16 audio card, reserve IRQ 5 for<br />

ISA/EISA use in the system BIOS (under PCI/Plug and Play Setup). See System Setup for<br />

instructions on using BIOS Setup to do this.<br />

PC Card Adapter<br />

If you change the default IRQ assignments in the system BIOS or if you reprogram the BIOS, you<br />

must reserve IRQ 11 for use with the PC Card adapter. This ensures correct operation of the PC<br />

Card adapter. See the System Board Manual for information on using BIOS Setup.<br />

When installing the audio card driver software on a system with a PC Card adapter running<br />

<strong>Windows</strong> NT 4.0, you may see a “new hardware found” message that asks you which driver to<br />

install. Select Do not install a driver. The PC Card adapter will work and the “new hardware<br />

found” message will not display again.<br />

Operating System <strong>Support</strong> for USB Peripherals<br />

Your system includes Universal Serial Bus (USB) ports for USB peripherals. <strong>Windows</strong> <strong>98</strong> and<br />

<strong>Windows</strong> 95 Service Release 2.1 (or later) support USB peripherals. <strong>Windows</strong> NT 4.0 does not<br />

support USB peripherals. Microsoft will add USB support to a future <strong>Windows</strong> NT release.<br />

System BIOS<br />

See System Setup for detailed information on BIOS configuration. Do not use the BIOS<br />

information the System Board Manual. Information on the following BIOS Setup parameters in<br />

System Setup has been updated:<br />

♦ Under Standard CMOS Setup/Boot Sector Virus Protection, the Optimal default setting is<br />

Disabled.<br />

♦ Under Advanced CMOS Setup/Default Primary Video, the Optimal default setting is PCI; the<br />

other setting is AGP.<br />

♦ Under Advanced CMOS Setup/Processor Serial Number, the Optimal default setting is<br />

Disabled. This parameter is for systems with Pentium III processors.<br />

Pentium III Processors<br />

Intel’s Streaming SIMD Extension Driver was installed on the system before shipment. This<br />

driver increases performance for drivers and applications designed to take advantage of it. If you<br />

reinstall the operating system, you should also reinstall this driver. You can find it in the QFE_SSE<br />

system software product, which you can get from the <strong>Support</strong> pages on the World Wide Web<br />

(http://www.intergraph.com/ics/) or the <strong>Intergraph</strong> System CD-ROM. See the README.TXT file<br />

delivered with QFE_SSE for more information.
