Study Notes

SaX2 of SuSE Linux is used to configure the hardware’s parameter,for example,graphics card,ethernet device.SaX2 acts as like Devices Administrator in Windows.
Yast administrates the files throught GUI which like Source Explorer in Windows.

“The device has been validated to run at 80MB/s and should support,(**) 320MB/s when the operating system is loaded” . Configure the RAID0 included two harddisk and left one disk.

What’s LVD?Low Voltage Differential.

#hostname 
#vi /etc/sysconfig/hostname

Using the above commands to show or set the system’s host name.

#vi /etc/inittab

find the strings like “id:x initdefault”. x=3 means startup in text mode,and x=5 means GUI mode.We could configure the x parameter to decide the mode which we want Linux to start in.

mount ISO files

#mount -o loop /abc.iso /mnt/cdrom

mount DVD.

#mount -t iso9660 /dev/dvd /mnt/cdrom
#mount -t udf /dev/dvd /mnt/cdrom

Check hardware info:

#cat /proc/cpuinfo
#cat /proc/meminfo
#cat /proc/interrupt
#cat /proc/ioports
#cat /proc/partitions         
#cat /proc/pci
#cat /proc/swaps

To configure the language of system.

#vi /etc/sysconfig/i18n

Convert cdrom files to ISO files.

#cp /dev/cdrom *.iso
#dd if=/dev/cdrom of=/tmp/*.iso

SMP: symmetric multiple processor
UP : unique process
bigmem: support memory which is more than 1G.

View the color setting by default.

#dircolor -p

If want to install other language package after completing install system,we would insert the RH 9.0 CD3, and then find the specific language package.

To select or un-select the service running.

#chkconfig --list
#ntsysc
#setup
