4. BIOS SETUP

Boot Menu

Plug & Play O/S [No]

This field allows you to use a Plug-and-Play (PnP) operating system to
configure the PCI bus slots instead of using the BIOS. When [Yes] is se-
lected, interrupts may be reassigned by the OS. When a non-PnP OS is
installed or you want to prevent reassigning of interrupt settings, select the
default setting of [No]. Configuration options: [No] [Yes]

Reset Configuration Data [No]

Configuration options: [No] [Yes]

Boot Virus Detection [Enabled]

This field allows you to set boot virus detection, ensuring a virus-free boot
sector.  The system halts and displays a warning message when it detects a
virus. If this occurs, you can either allow the operation to continue or use a
virus-free bootable floppy disk to restart and investigate your system. Con-
figuration options: [Disabled] [Enabled]

Quick Power On Self Test [Enabled]

This field speeds up the Power-On-Self Test (POST) routine by skipping
retesting a second, third, and fourth time. Configuration options: [Disabled]
[Enabled]

Boot Up Floppy Seek [Enabled]

When enabled, the BIOS will seek the floppy disk drive to determine
whether the drive has 40 or 80 tracks. Configuration options: [Disabled]
[Enabled]
