of supporting two ATA devices (Master and Slave). Use this setting to
disable one or more of these integrated channels. You should modify
this setting only if specified in other sections of this manual. The
default is Both.
• Write Protect Boot Sector—When set to Yes, this setting prevents
modification of a hard disk boot sector via INT 13h services, which
may help prevent certain computer viruses from infecting the
controller. This setting does not prevent boot sector modification by
32-bit operating system drivers that access the hard disk directly. The
default is No.
• Quick Boot Mode—When you enable this option, certain lengthy
BIOS tests that rarely fail are skipped to shorten controller boot time.
The default is Enabled.
• Summary Screen—This setting controls the display of the summary
screen shown after BIOS completes its initialization, but before
booting takes place. 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.
• Serial Port A & B—This setting enables or disables COM1 and
COM2, respectively. You can also change this setting to Enabled and
modify the base address and Interrupt Request Level (IRQ) of a port.
The default is Auto, which places COM1 at 0x3F8 IRQ 4 and COM2
at 0x2F8 IRQ 3.
• Parallel Port—Use this setting to enable or disable LPT1. You can
also change this setting to Enabled and modify the base address, IRQ
level, and ISA Direct Memory Access (DMA) channel of the port. The
default is Auto, which places LPT1 at 0x378, IRQ 7, using ISA DMA
Channel 3 if necessary.
• Parallel Port 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
specifically requires a nondefault setting, you can change it here. The
default is Bidirectional, for full IEEE 1284 capabilities.
• Floppy Drive—You can route the internal signals used for the 3.5 in.
floppy drive operation through the pins on the parallel port connector.
