P4VTB BIOS Setup
MODEM Use IRQ
This determines the IRQ, which can be applied in MODEM use.
The Choices: 3 (default)/ 4 / 5 / 7 / 9 / 10 / 11 / NA
Soft-Off by PWR-BTTN
Pressing the power button for more than 4 seconds forces the system to enter the
Soft-Off state when the system has "hung."
The Choices: Delay 4 Sec, Instant-Off (default).
Ac Loss Auto Restart
This field determines the action the system will automatically take when power is restored
to a system that had lost power previously without any subsequent manual intervention.
There are 3 sources that provide current to the CMOS area that retains these Power-On
instructions; the motherboard battery (3V), the Power Supply (5VSB), and the Power
Supply (3.3V). While AC is not supplying power, the motherboard uses the motherboard
battery (3V). If AC power is supplied and the Power Supply is not turned on, 5VSB from
the Power Supply is used. When the Power Supply is eventually turned on 3.3V from the
Power Supply will be used.
There are 3 options: "Former-Sts", "On", "Off".
"Off" (default) Means always set CMOS to the "Off" status when AC power is lost.
"On" Means always set CMOS to the "On" status when AC power is lost
"Former-Sts" Means to maintain the last status of the CMOS when AC power is lost.
For example: If set to "Former-Sts" and AC power is lost when system is live, then after
AC power is restored, the system will automatically power on. If AC power is lost when
system is not live, system will remain powered off.
Chassis Open Warning
This item allows you to enable or disable chassis open warning beep sound.
The Choices: Disabled (default), Enabled.
IRQ/Event Activity Detect
If you highlight the literal "Press Enter" next to the "IRQ/Event Activity Detect" label and
then press the enter key, it will take you a submenu with the following options:
VGA
When set to On, any event occurring at a VGA Port will awaken a system which
has been powered down.
The Choices: Off (default), On.
LPT & COM
When this option is set to On, any event occurring at a COM(serial)/LPT (printer)
port will awaken a system which has been powered down.
The Choices: LPT/COM (default), COM, LPT, NONE.
