Important Notice from AMI
Change in Baby Voyager BIOS Setup
Technical Note
Series 39 Baby Voyager BIOS Setup
Date: 8/23/91
Subject: New Advanced Chip Set Setup Options for Baby Voyager
BIOS Setup
The following five additional Setup options now appear on the
Advanced Chip Set Setup screen. They are the first five options
on the screen.
On Board Serial Port 1
This option enables or disables serial port 1 on the Baby Voyager
motherboard. The options are I/O ports 3F8h - 3FFh, I/O ports
3E8h - 3EFh, or Disabled.
If the configuration data stored in CMOS RAM is corrupted when
the system is powered on, the system BIOS automatically
configures onboard serial port 1 according to the presence or
absence of serial ports on any adapter cards in the system
expansion slots (off board serial ports).
Autoconfiguration will only occur when CMOS RAM data is
corrupted. The result for serial port 1 is:
If the Offboard the Onboard Serial Port 1 is Autoconfigured as
Serial Port is
None 3F8h Can be disabled or changed to 3E8h
via BIOS Advanced Chip Set Setup.
3F8h 3E8h Can be disabled via BIOS Advanced
Chip Set Setup. If changed to
3F8h, an I/O port address conflict
occurs.
3E8h 3F8h Can be disabled via BIOS Advanced
Chip Set Setup. If changed to
3E8h, an I/O port address conflict
occurs.
3F8h, 3E8h Disabled If changed to 3F8h or 3E8h, an I/O
port address conflict occurs.
P5 is serial port 1 on the Baby Voyager motherboard. If disabled
through Setup, do not attach any device to P5 or to any cable
attached to P5. J9 is used to configure the interrupt request
line (IRQ) for onboard serial port 1.
New Advanced Chip Set Setup Options, Continued
J9
The options for J9 are:
Jumper Pins Shorted Description
J9 Pins 1-2 IRQ3 selected for onboard
serial port 1.
J9 Pins 2-3 IRQ4 selected for onboard
serial port 1 (Default).
If onboard serial port 1 is disabled, you may want to remove the
jumper block from J9 to disable the onboard serial port 1
interrupt.
On Board Serial Port 2
This option enables or disables serial port 2 on the Baby Voyager
motherboard. The options are I/O Ports 2F8h - 2FFh, I/O Ports
2E8h - 2EFh, or Disabled.
If the configuration data stored in CMOS RAM is corrupted when
the system is powered on, the system BIOS automatically
configures onboard serial port 2 according to the presence or
absence of serial ports on any adapter cards in the system
expansion slots (off board serial ports).
Autoconfiguration will only occur when CMOS RAM data is
corrupted. The result for serial port 2 is:
If the the Onboard
Offboard Serial Port 2
Serial Port is is
Autoconfigured
as
None 2F8h Can be disabled or changed to 2E8h
via BIOS Advanced Chip Set Setup.
2F8h 2E8h Can be disabled via BIOS Advanced
Chip Set Setup. If changed to
2F8h, an I/O port address conflict
occurs.
2E8h 2F8h Can be disabled via BIOS Advanced
Chip Set Setup. If changed to
2E8h, an I/O port address conflict
occurs.
2F8h, 2E8h Disabled If changed to 2F8h or 2E8h, an I/O
port address conflict occurs.
P4 is serial port 2 on the Baby Voyager motherboard. If disabled
through Setup, do not attach any device to P4 or to any cable
attached to P4. J6 is used to configure the interrupt request
line (IRQ) for onboard serial port 2.
New Advanced Chip Set Setup Options, Continued
J6
The options for J6 are:
Jumper Pins Shorted Description
J6 Pins 1-2 IRQ4 selected for onboard
serial port 2.
J6 Pins 2-3 IRQ3 selected for onboard
serial port 2 (Default).
If onboard serial port 2 is disabled, you may want to remove the
jumper block from J6 to disable the onboard serial port 2
interrupt.
On Board Parallel Port
This option enables or disables the onboard parallel port. The
options are I/O ports 378h - 37Fh, I/O ports 278h - 27Fh, or
Disabled. P3 is the onboard parallel port.
If the configuration data stored in CMOS RAM is corrupted when
the system is powered on, the system BIOS automatically
configures the onboard parallel port according to the presence or
absence of parallel ports on any adapter cards in the system
expansion slots (off board parallel ports).
Autoconfiguration will only occur when CMOS RAM data is
corrupted. The result for the onboard parallel port is:
If the the Onboard
Offboard Parallel Port
Parallel Port is
is Autoconfigured
as
None or 3BCh 378h Can be disabled or changed to 278h
via BIOS Advanced Chip Set Setup.
378h 278h Can be disabled via BIOS Advanced
Chip Set Setup. If changed to
378h, an I/O port address conflict
occurs.
278h 378h Can be disabled via BIOS Advanced
Chip Set Setup. If changed to
278h, an I/O port address conflict
occurs.
378h, 278h Disabled If changed to 378h or 278h, an I/O
port address conflict occurs.
P3 is the parallel port on the Baby Voyager motherboard. If
disabled through Setup, do not attach any device to P3 or to any
cable attached to P3. J18 is used to configure the interrupt
request line (IRQ) for the onboard parallel Port.
New Advanced Chip Set Setup Options, Continued
J18
The options for J18 are:
Jumper Pins Shorted Description
J18 Pins 1-2 IRQ5 selected for the
onboard parallel port.
J18 Pins 2-3 IRQ7 selected for the
onboard parallel port
(Default).
If the onboard parallel port is disabled, you may want to remove
the jumper block from J18 to disable the onboard parallel port
interrupt.
On Board Floppy Controller
Enable this option to use the onboard floppy controller. Make
sure that the floppy cable is connected to P6 on the Baby Voyager
motherboard.
On Board IDE Controller
Enable this option to use the onboard IDE hard disk drive
controller. Make sure that the IDE cable is connected to P7 on
the Baby Voyager motherboard.
