The Disabled option means that setup will not be considered during
the boot process.
IDE-0, IDE-1, IDE-2, IDE-3 are the four hard disks than can be installed
by the BIOS. IDE-0 is the first hard disk installed by the
BIOS, IDE-1 is the second hard disk, and so on. For example, if the
system has a hard disk connected to Primary Slave and another
hard disk to Secondary Master, then IDE-0 will be referred to as the
hard disk connected to Primary Slave and IDE-1 will be referred to
as the hard disk connected to the Secondary Master. IDE-2 and
IDE-3 are not present. Note that the order of the initialization of the
devices connected to the primary and secondary channels are Primary
Master first, Primary Slave second, Secondary Master third,
and Secondary Slave fourth.
The BIOS will attempt to read the boot record from 1st, 2nd, 3rd,
and 4th boot device in the selected order until it is successful in
reading the booting record. The BIOS will not attempt to boot from
any device which is not selected as the boot device.

2-1-5 PCI/PnP Setup
Plug and Play-Aware OS
The settings for this option are Yes or No. The Optimal and Fail-
Safe default settings are No. Set this option to Yes if the operating
system in the computer is aware of and follows the Plug and Play
specification. AMIBIOS only detects and enables PnP ISA adapter
cards that are required for system boot. Currently, only Windows
95' is PnP-Aware. Set this option to No if the operating system
(such as DOS, OS/2, Windows 3.x) does not use PnP. You must
set this option correctly. Otherwise, PnP-aware adapter cards installed
in the computer will not be configured properly. This option
can be safely set to No in Windows 95'.
Offboard PCI IDE Primary IRQ
Offboard PCI IDE Secondary IRQ
These options specify the PCI interrupt used by the primary (or secondary)
IDE channel on the offboard PCI IDE controller. The settings
are Disabled, Hardwired, INTA, INTB, INTC, or INTD. The
Optimal and Fail-Safe default settings are Disabled.
PCI Slot 1 IRQ Priority
PCI Slot 2 IRQ Priority
PCI Slot 3 IRQ Priority
PCI Slot 4 IRQ Priority
The settings are Auto, 3, 4, 5, 7, 9, 10, 11, 12, 14 or 15. The
Optimal and Fail-Safe default settings are Auto.
DMA Channel 0
DMA Channel 1
DMA Channel 3
DMA Channel 5
DMA Channel 6
DMA Channel 7
The settings are PnP or ISA/EISA. The Optimal and Fail-Safe default
settings are PnP.
IRQ3
IRQ4
IRQ5
IRQ7
IRQ9
IRQ10
IRQ11
IRQ12
These options specify which bus the specified IRQ line is used on
and allow you to reserve IRQs for legacy ISA adapter cards. If more
IRQs must be removed from the pool, the end user can use these
options to reserve the IRQ by assigning an ISA/EISA setting to it.
Onboard I/O is configured by AMIBIOS. All IRQs used by onboard I/
O are configured as PCI/PnP.
IRQ14 and 15 will not be available if the onboard PCI IDE is enabled.
If all IRQs are set to ISA/EISA and IRQ14 and 15 are allocated
to the onboard PCI IDE, IRQ 9 will still be available for PCI
and PnP devices. This is because at least one IRQ must be available
for PCI and PnP devices.
The settings are ISA/EISA or PCI/PnP. The Optimal and Fail-Safe
default settings are PCI/PnP, except for IRQ 12.
2-1-6 Peripheral Setup

2-2 Security Setup
2-2-1 Supervisor
User
The system can be configured so that all users must enter a password
every time the system boots or when the WINBIOS setup is
executed. You can set either a Supervisor password or a User
password. If you do not want to use a password, just press
when the password prompt appears.
The password check option is enabled in the Advanced Setup by
choosing either Always or Setup. The password is stored in CMOS
RAM. You can enter a password by typing the password on the
keyboard, selecting each letter via the mouse, or selecting each
letter via the pen stylus. Pen access must be customized for each
specific hardware platform.
When you select Supervisor or User, AMIBIOS prompts for a password.
You must set the Supervisor password before you can set
the User password. Enter a 1-6 character password. The password
does not appear on the screen when typed. Retype the new
password as prompted and press
down. If you forget it, you must drain CMOS RAM and reconfigure
the system.
2-2-2 Anti-Virus
When this icon is selected, AMIBIOS issues a warning when any
program (or virus) issues a disk format command or attempts to
write to the boot sector of the hard disk drive. The settings are
Enabled or Disabled. The Optimal and Fail-Safe default settings
are Disabled.
2-3 Utility Setup
