Installation Guide(For example:RHEL5.4 32bit)
=============================================

1. enter into the driver package directory

	cd ./rhel5.4_32bit

2. Run the install script
	
    	chmod +x ./install
	./install


The driver will be installed into /usr/lib/xorg/modules/drivers


Knowing issues/limitations
==========================
1.  Do not support Multi Card Dual View in SLES11 32bit/64bit. SMI will release the dual view driver in Q2,2010

2.  May can not boot into XWindow and encounter black screen in some Monitors after install a new RHEL5.4/5.5 OS. This issue is caused by the wrong SM712 Inbox XWindow display driver in RHEL5.4/5.5.
     We can use the following steps to skip the OS inbox driver loading:
	a)	Boot the OS. After about one minutes, please press Ctrl+Alt+F2 to change another terminal.
	b)	Now you can login into the linux with console.  Install Correct SM712 driver package.
	c)	it's OK.	 

3.  Default xorg.conf will set display mode to 1024x768 in order to make sure the driver can be loaded,
    user can change the mode in the display section by themselves.
