開機畫面的選擇

首先把要開機Logo圖片(png格式)放在linux2.6.14文件中的 drivers/video/logo中，終端選擇進入drivers/video/logo目錄，進行以下操作：
(假設開機圖片名為linux.png)
# pngtopnm linux.png > linuxlogo.pnm

# pnmquant 224 linuxlogo.pnm > linuxlogo224.pnm

# pnmtoplainpnm linuxlogo224.pnm >linuxlogo224.ppm

# mv linuxlogo224.ppm logo_linux_clut224.ppm //替換原來的啟動文件

安裝 tftpd-hpa 與 xinetd

在Ubuntu下，tftp是不能單獨運作的，需要xinetd這個網路管理的背景程式之支援。於是我們同時安裝這兩個套件。

$ sudo apt-get install tftpd-hpa xinetd

[編輯] xinetd.conf 設定

安裝完tftp與xinetd後，需要在xinetd的設定檔/etc/xinetd.conf中寫入相關設定。

$cat /etc/xinetd.conf
# Simple configuration file for xinetd
# Some defaults, and include /etc/xinetd.d/
defaults
{
# Please note that you need a log_type line to be able to use log_on_success
# and log_on_failure. The default is the following :
# log_type = SYSLOG daemon info
}
includedir /etc/xinetd.d

雖然我們可以將設定內容寫入此處，但還有更好的設定檔設定方法。xinetd.conf引入專門存放設定檔的資料夾includedir /etc/xinetd.d。因此更結構化的設定檔配置就是自己建立一個tftp設定檔於此資料夾內。

$sudo vim /etc/xinetd.d/tftp

存入

service tftp
{
socket_type = dgram
protocol = udp
wait = yes
user = root
server = /usr/sbin/in.tftpd
server_args = -s /var/lib/tftpboot
disable = no
per_source = 11
cps = 100 2
flags = IPv4
}

由於背景網路程式已經由inetd更換成xinetd，可將/etc/inetd.conf中關於tftp的部份註解以避免混淆。

#:BOOT: TFTP service is provided primarily for booting. Most sites
# run this only on machines acting as "boot servers."
#tftp dgram udp wait nobody /usr/sbin/tcpd /usr/sbin/in.tftpd /srv/tftp

完成以上設定後，還需要讓xinetd讀入新參數並重新啟動。

sudo /etc/init.d/xinetd reload
sudo /etc/init.d/xinetd restart


檢查一下tftp是否真的在運作

$ sudo netstat -anp | grep tftp
udp 0 0 0.0.0.0:69 0.0.0.0:* 5249/in.tftpd
unix 2 [ ] DGRAM 17654 5249/in.tftpd

Command to set Android IP,DNS

RTC support in SMDK6410 Android (Linux 2.6.27)

Enable the option...
menuconfig => Device Driver => Real Time Clock =>
select all above "*** I2C RTC driver"

And you can see the /dev/rtc0 & /dev/rtc1 under console.


How to verify RTC?

Try to set date(# date -s 20090324.150000) in system, and the time will change.

如何擴大Vmware 原來建立的硬盤大小

參考: http://milton.bloghome.cn/posts/103705.html

vmware安裝目錄下
vmware-vdiskmanager.exe
在dos提示符下運行,不加任何參數時,給出此程序使用方法:
---------------------------------------------------------------------
VMware Virtual Disk Manager - build 12544.
Usage: vmware-vdiskmanager.exe OPTIONS diskName | drive-letter:
Offline disk manipulation utility
Options:
-c : create disk; need to specify other create options
-d : defragment the specified virtual disk
-k : shrink the specified virtual disk
-n : rename the specified virtual disk; need to
specify destination disk-name
-p : prepare the mounted virtual disk specified by
the drive-letter for shrinking
-q : do not log messages
-r : convert the specified disk; need to specify
destination disk-type
-x : expand the disk to the specified capacity
Additional options for create and convert:

D:\VM>c:vmware-vdiskmanager.exe -x 20GB Ubuntu.vmdk
Failed to expand the disk 'Ubuntu.vmdk': An error occurred while writing a file;
the disk is full. Data has not been saved. Free some space and try again (0xd00
000008).

我試過，可是不成功...感覺像是硬碟要有新Size的空間，VM tool 幫你做 ghost 而已....

Fedora 8 可用的開機選單修改方式

參考 http://blog.nanaimoinn.com/index.php?blog=3&p=329&more=1&c=1&tb=1&pb=1

要變更fedora Core 4中 grub的開機選單,可以用文字編輯器將下列檔案打開.

/etc/grub.conf

其中

default=0 是指預設的那一個作業系統來開機的選項.

timeout=30 是指30秒後grub自動以預設的作業系統來進行開機.

title 其字串為供開機選單選擇的字串.
