Our BIOS default COM3 IRQ=5 / COM4 IRQ=10,but even We provide the physical IRQ to COM3/COM4 then Linux kernel still use the IRQ share mode.
So you can see supported and detected message form #dmesg |grep ttyS,but COM3&COM4 doesn't work.
Now you have 2 choices for this problem

1.change your BIOS setting
COM3=IRQ 4 and COM4=IRQ3

2.Use the software command change to IRQ share
#sudo setserial /dev/ttyS2 irq 0
#sudo setserial /dev/ttyS3 irq 0.

How to get setserial
#sudo apt-get install setserial (for Ubuntu)
#yum install setserial (for Fedora)

In X window, display mode will be controled by "driver", doesn't matter what you setting in bios

there are two runlevels in linux

1. Graphic mode ( X window ): controled by driver

2. console mode ( text mode ): controled by bios setting

all we talking about situation is "After driver installed".

In Windows, execute the S3Utility.exe to modfify what you want to do.

In Linux, use command "s3utility" in terminal of X window, then you and adjust display mode you need

(needed to be relogin X window to display)

1. execute the utility " s3utility " (Screenshot.jpg), you can see supported device

(In s3utility, check the "samm mode" button to set mode to dual-head view otherwise uncheck this to clone)

2. driver already be installed if you can execute the s3utility

Or execute command "lsmod"(list the modules) to find via driver out

先前使用CV860開發客戶,若是使用較舊版本的Linux 如:Trustix Linux2.0或Kernel 2.4.x, 將有可能發現IDE裝置無法辨識的問題,產生現象會有

1. Linux Install-CD 無法正常安裝
2. 無法找尋到安裝硬碟,

建議客戶轉移至CV700時不要使用舊版Kernel 2.4.x,此問題可藉由update kernel至Kernel 2.6.x解決,如 Trustix linux3.0 版本已解決 CV700 IDE裝置無法辨識的問題!!

Kernel update can download form http://kernel.org/

• Install WinCE 6.0 IDE driver and enable it at "Catalog Items View" in Platform Builder 6.0.

Location is : Third Party -> Devices Drivers -> VIA PATA/SATA Storage Block Driver

• Disable original ATAPI driver at "Catalog Items View" in Platform Builder 6.0.

Location is : Device Drivers -> Storage Devices -> ATAPI PCI Support

• IDE driver

Because "VIA PATA/SATA Storage Block Driver" is not support Hive-base,so you should choose "ATAPI PCI Support" when runing Hive-base
ps."VIA PATA/SATA Storage Block Driver" and "Hive-base" can not coexist.

You can change the resolution to solve the question:

1. Plus "1" at the kernel line of GRUB menu in order to go into single user mode.
2. Edit the /etc/X11/xorg/xorg.conf and add <Modes "1024x768"> between <Depth 24> and <EndSubSection>
3. Reboot,and the problem will be solved.

The problem might be caused by the shortage of the space.

If you get the error message as previous picture, create a larger space for "/" or install less software might soive the problem.

In linux , you can type "sensors" in terminal,and you can get the correct temperature.

Or use this tool in earlier linux. hardware_monitor

In windows XP,you can use this tool. hardware_monitor

FreeBSD ACPI software is not compatible with VIA's chip.

Because of VIA cannot support FreeBSD.

We can just turn off the error message.

You can turn off the error message of temp of acpi part:

add " hw.acpi.thermal.polling_rate=0" into

/etc/sysctl.conf

Using Standard FreeBSD to test (pfSense was FreeBSD7.0 base),

System works fine after FreeBSD 7.0 installed successfully and rebooted.

so we think that existed only on pfSense.

In the 8086/8088,there are only 20 address lines.In other words,there are 1MBytes of memory.

In order to keep the number of transistors on their chips to a minimum,Intel decided to wrap around address above the 1 megabyte mark to the beginning of memory.

As the (a) picture of below picture.

After 80286,there are 24 address lines.There are 16MBytes of memory.

System can go into the real area which above 1MBytes.

As the (b) picture of below picture.

In order to remain compatible with the 8086,Intel use some pins of the keyboard controller to control the 21th line of the address lines , named Gate A20.

On several newer coputers , the chipset has a FAST A20 option to control the A20 line instead of the keyboard controller.

We can choose between controlling Gate A20 by chipset or by keyboard controller from BIOS.
