Reset Configuration Data
- Reset Configuration Data: When set to Enabled, ESCD
(Extended System Configuration Data) is cleared. This setting will automatically be set
back to Disabled when the system reboots.
Enabled
and
Disabled
(default).
IRQ3/4/5/7/9/10/11/12/14/15, DMA0/1/3/5/6/7 assigned to
- By default, all resources are
assigned to the PCI Bus except IRQs 3 and 4. If an ISA card requires a particular IRQ or
DMA channel, those resources should be set to Legacy ISA so that the PCI Bus will not try
to use them. Choices are
Legacy ISA
and
PCI/ISA PnP
.
PCI IRQ Activated By
- This sets the method by which the PCI bus recognizes that an IRQ
service is being requested by a device. Under all circumstances, you should retain the
default configuration unless advised otherwise by your system’s manufacturer. Choices are
Level
(default) and
Edge
.
PCI IDE IRQ Map To
- Configures what type of IDE disk controller is in use. By default,
Setup assumes that you are using the on-board PCI IDE Controller and this option is set to
PCI-AUTO
. If you have equipped your system with an add-on PCI controller, changing this
setting allows you to specify which slot has the controller and which PCI interrupt (A, B, C
or D) is associated with the Primary and/or Secondary port. Most add-on IDE controllers are
configured to use INT# A for the primary and INT# B for the secondary.
On Board SCSI BIOS
- When set to
Auto
(Default), the system will automatically sense
the presence of any SCSI adapter that uses a Symbios SYM53C8XX SCSI chip:
If the SCSI adapter installed
has
its own
BIOS on board:
The on-board SCSI BIOS will not be loaded.
The adapter’s own SCSI BIOS will be used.
If the SCSI adapter installed
doesn’t have
its own BIOS and the card uses or is
compatible with the SYM53C8XX chip:
The on-board SCSI BIOS will load and
control the SCSI adapter.
*Disabling
, the onboard SCSI BIOS prevents it from being active in any way.
PCI Latency Timer
- This option sets latency of all PCI devices on the PCI bus. The
settings are in units equal to PCI clocks. Available settings are 0 ~ 248. The default is 80.
LOAD BIOS DEFAULTS
Loads “Fail Safe” settings into the BIOS Setup program. These options are designed to slow
