How to Use the COM3 / CMO4 under Ubuntu or other Kernel 2.6.x

Ans:

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.

由CV860轉移至CV700 Linux客戶,注意事項

Ans:

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!!

When I installed CentOS 5.0 on CV700A with a flat panel monitor,The monitor goes black with a message that says "out of range".

Ans:

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.

It shows "acpi_tz0: _TMP value is absurd, ignored (-247.7C)" every 10 seconds in FreeBSD 7.0 on CV700A.How can I stop it?

Ans:

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
