Study Notes

In Fedora Core 3, I installed mplayer with rpm package. Issuing the following command to play DVD programs:

# cat /etc/fstab  

Identify the dvd mounting point.For example, the location is /dev/hdc.

# mplayer /dev/hdc

Then a playing windown jumpes out, and it will play the DVD .However , I still could not play the file as wmv format. I found the reason may be mplayer should get better performance through compliering installation which will get play in higher quarlity and I/O rate.Realplay10 for linux also be installed in my computer,but I can only hear the voice,no picture displayes.I have not found the key to resolve this problem.

Fedora 1 in SE7520JR2
After installing Fedora1 in SE7520JR2(PR2700) platform, I try to add two ethernet device which are Marvell and Intel Pro1000 to the operating system.First,Intel Pro1000 device was choose to install, at final step,I issue the following command:insmod e1000, in order to add device to the running kernel.Second,complied the Marvell source code.But some thing wrong happened.Only one ethernet device was found in the module list through executing the command:

#dmesg | grep eth

So I changed the queue .Install Marvell at first and then install Intel Pro1000 device.Hmmm,

#lsmod sk98lin          
- dedicate the Marvell ethernet deviee was active.
#lsmod e1000            
- in this way,I found e1000 module was unused.

Then, I used the command:

#ifconfig eth1 up

One ethernet device(Marvell) was found in the network device list,but two hardware recognized by the Linux were listed.

#cd /etc/sysconfig/network-script
#cp ifcfg-eth0 ifcfg-eth1

and edit parameters in ifcfg-eht1.

# service network restart

OK,two network devices were installed successfully.
