ofsupporting two ATAdevices (Master and Slave). Use this setting to
disable one or more of these integrated channels. Youshould modify
this setting only if specifiedin other sectio ns of this manual. The
defaultis Both.
•Write Protect Boot Sector—When set to Yes, this setting prevents
modificationof a hard di sk boot sector via INT 13h services, which
may help preventcertain computer viruses from infecting the
controller.This setting does not prevent boot sector modification by
32-bitoperating system drivers that access the hard disk directly. The
defaultis No .
•Quick Boot Mode—When you enable this option, certain lengthy
BIOS tests that rarely fail are skipped to shorten controller boot time.
The defaultis Enabled.
•Summary Screen—This setting controls the display of the summary
screen shownafter BIOS completes its initialization, but before
booting takesplace. You can disable this screen in the interest of
shortening controller boot time. The default is Disabled.
Integrated Peripherals Submenu
Use this submenu to apply nondefault configurations to the front panel
peripherals of an NI 8171 series controller. Normally, you do not need to
modify these settings, as the factory default settings provide the most
compatible and optimal configuration possible.
•SerialPort A & B —This setting enables or disables COM1 and
COM2,respectively. Youcan also change this setting to Enabled and
modify the base address and Interrupt Request Level(IRQ) of a port.
Thedefault is Auto, which places COM1 at 0x3F8 IRQ 4 and COM2
at 0x2F8 IRQ 3.
•ParallelPort—Use this s etting to enable or disable LPT1. Youcan
alsochange this setting to Enabled and m odify the baseaddress, IRQ
level,and ISA Direct Memory Access (DMA) channel of the port. The
defaultis Auto, which places LPT1 at 0x37 8, IRQ 7, using ISA DMA
Channel3 if necessary.
•ParallelPort Mode—The PC industry has created several different
modes of operation for this port over the years. Usually,the default
setting works for all applications. However,if a parallel port device
specificallyrequires a nondefault setting , you can change it here. The
defaultis Bidirectional ,for full IEEE 1 284 capabilities.
•FloppyD rive—Youcan route the internal signals used for the 3.5 in.
floppydrive operation through the pins on the parallel port connector.
Use this setting to operate the NI 8171 series controller with a
