Targa 2000 RTX Card
To use a Targa 2000 RTX card with the system’s Sound Blaster 16 audio card, reserve IRQ 5 for
ISA/EISA use in the system BIOS (under PCI/Plug and Play Setup). See System Setup for
instructions on using BIOS Setup to do this.
PC Card Adapter
If you change the default IRQ assignments in the system BIOS or if you reprogram the BIOS, you
must reserve IRQ 11 for use with the PC Card adapter. This ensures correct operation of the PC
Card adapter. See the System Board Manual for information on using BIOS Setup.
When installing the audio card driver software on a system with a PC Card adapter running
Windows NT 4.0, you may see a “new hardware found” message that asks you which driver to
install. Select Do not install a driver. The PC Card adapter will work and the “new hardware
found” message will not display again.
Operating System Support for USB Peripherals
Your system includes Universal Serial Bus (USB) ports for USB peripherals. Windows 98 and
Windows 95 Service Release 2.1 (or later) support USB peripherals. Windows NT 4.0 does not
support USB peripherals. Microsoft will add USB support to a future Windows NT release.
System BIOS
See System Setup for detailed information on BIOS configuration. Do not use the BIOS
information the System Board Manual. Information on the following BIOS Setup parameters in
System Setup has been updated:
♦
Under Standard CMOS Setup/Boot Sector Virus Protection, the Optimal default setting is
Disabled.
♦
Under Advanced CMOS Setup/Default Primary Video, the Optimal default setting is PCI; the
other setting is AGP.
♦
Under Advanced CMOS Setup/Processor Serial Number, the Optimal default setting is
Disabled. This parameter is for systems with Pentium III processors.
Pentium III Processors
Intel’s Streaming SIMD Extension Driver was installed on the system before shipment. This
driver increases performance for drivers and applications designed to take advantage of it. If you
reinstall the operating system, you should also reinstall this driver. You can find it in the
