How to use the raid in arch-linux for HP8300

[Albertyhl]

Hi ,

I am just face a problem that I can't install the arch-linux to HP8300, every time I boot up the computer by Linux, the OS is only install in RAM, which mean, I can't storage data onto the harddisk anymore.

So pls kindly advise the solution for install the linux onto the HP8300?

Thx for your help.
