I would let everybody aware how to reflash the "Flash Disk Module" and Reinstall the image to N5200
1. open the N5200 case, you can see the VGA port location
2. take out the router daughter card
3. solid the VGA header on the motherboard
4. install the Linux OS to USB thumb you can found out as follow web site
www.pendrivelinux.com , I choose Fedora 9
5. plug the bootable Fedora 9 USB thumb to the bottom of back panel
6. connect the USB Hub on the top and then plug the USB keyboard and Mouse
7. power on the N5200
8. check the BIOS setting, you MUST change the first boot device to USB-HDD for boot up the N5200 through Fedora 9
9. username : root
10. copy the "hda" image file to the Desktop from other USB storage device. Save as the image file of following website
www.masterid.de/hda11. check the Flash Disk whether able to write permission, if not you should change that, otherwise you cannot write the image file to there.
12. if everything is positive, open the "Terminal" program to entry the command as follow
the Terminal path is : Applications->System Tools->Terminal
cd /root/Desktop
dd if=./hda of=/dev/sda1 bs=1024
PS:
a. "hda" is image file
b. "sda1" is Flash Disk Module mounted in Fedora 9 device name
13. if shown copied xxxxxxkb, you have successful to write the image file to Flash Disk Module
14. power off the N5200
15. take out the USB thumb and power on the N5200
16. you can through the monitor to see the booting
17. use the factory_reset.sh Script and firmware to reinstall the factory default
18. CHEERS!!! Ha...Ha.... ;D
Finally, I do not know how to insert the image to here, if someone can ask me I will replenishment here.
