Chapter 2 Installation and BIOS Setup
© National Instruments Corporation 2-11 NI 8352/8353 User Manual
Latency Timer
Use this setting to set the clock rate for Bus Master. A high-priority,
high-throughout device may benefit from a greater clock rate. The options
are Default, 0020h, 0040h, 0060h, 0080h, 00A0h, 00C0h, and 00E0h. For
Unix, Novell, and other operating systems, select the other option. If a
drive fails after installing new software, you may want to change this
setting and try again. A different OS requires a different Bus Master
clock rate.
Large Disk Access Mode
This setting determines how large hard drives are accessed. The options are
DOS (default) or Other (for Unix, Novell NetWare, and other operating
systems).
Advanced Chipset Control
Access this submenu to change the following settings.
Caution Be careful when changing the advanced settings. Incorrect values may cause
system malfunction. Also, a very high DRAM frequency or incorrect DRAM timing may
cause system instability. When this occurs, revert to the default setting.
Clock Spectrum Feature
If enabled, the BIOS monitors the level of electromagnetic interference
caused by the components and attempts to decrease the interference
whenever needed. The options are Enabled and Disabled (default).
ECC Conditions
This setting specifies the ECC error conditions treated as ECC Error Events
by the system. The options are None, Single Bit, Multiple Bit (default),
and Both.
Note This item is available only when memory supports it.
ECC Error Handler
Use this setting to select the type of interrupt activated as a result of an
ECC error. The options are None, NMI (Non-Maskable Interrupt),
SMI (System Management Interrupt) (default), and SCI (System
Control Interrupt).
Note This item is available only when memory supports it.
