Service and Technical Reference Guide, xw3100
Allows you to set: (continued)
POST Delay (in seconds) (enable/disable). Enabling this feature
will add a user-specified delay to the POST process. This delay
is sometimes needed for hard disks on some PCI cards that spin
up very slowly; so slowly that they are not ready to boot by the
time POST is finished. The POST delay also gives you more time
to select F10 to enter Computer (F10) Setup.
I/O APIC Mode (enable/disable). Enabling this feature will
allow Microsoft Windows Operating system to run optimally.
This feature must be disabled for certain non-Microsoft
Operating Systems to work properly.
ACPI/USB Buffers @ Top of Memory (enable/disable).
Enabling this feature places USB memory buffers at the top of
memory. The advantage of remapping is that it allows space in
the DOS Compatibility Hole range, below 1MB, to be made
available for additional PCI plug-in cards that need option
ROM space. The disadvantage is that a popular memory
manager, HIMEM.SYS, does not work properly when USB
buffers are at top of memory AND the system has 64 KB or less
of RAM.
NIC Option ROM Download (enable/disable). The BIOS
contains an embedded NIC option ROM to allow the unit to
boot through the network to a PXE server. This is typically used
to download a corporate image to a hard drive. The NIC
option ROM takes up memory space below 1MB commonly
referred to as DOS Compatibility Hole (DCH) space. This space
is limited. This F10 option will allow users to disable the
downloading of this embedded NIC option ROM thus giving
more DCH space for additional PCI cards which may need
option ROM space. The default will be to have the NIC option
ROM enabled.
Allows you to set resources for or disable onboard system
devices (serial port, parallel port, or diskette controller).
Lists currently installed PCI devices and their IRQ settings.
Allows you to reconfigure IRQ settings for these devices or to
disable them entirely. These settings have no effect under an
APIC-based operating system.
