Installation
===========================================

make sure to boot the kernel version you want to install DRI with
and the kernel source code is installed in /usr/src/linux-2.4.x/

if the kernel source is not built before, make sure to run
'make mrproper' & 'make menucofing' (save default setting) & "make dep' 
in kernel directory

Also make sure kernel config is the same as the version currently 
running. 

**If you have install XGI package before, you better uninstall it NOW.
**(see sec. 7 Uninstall)

After Kernel Source is Ready and you login as root , then

'cd XGIPKG'
'sh install.sh'

it will compile needed kernel modules and copy modules to 
Systems Directories.
 
Detail in install.sh:
1.recompile xgifb.o in XGIPKG/FB/ 
  compile log in compile.log
2.recompile xgi.o in XGIPKG/drm/
  compile log in compile.log
3.copy xgifb.o to /lib/modules/2.4.x/kernel/drivers/video/xgi/
  (create directory if not exist)
  copy xgi.o to /lib/modules/2.4.x/kernel/drivers/char/drm/
4.copy xgi_drv.o to /usr/X11R6/lib/modules/drivers/
  copy xgi_dri.so to /usr/X11R6/lib/modules/dri/
  copy libGL.so.1.2 /usr/X11R6/lib/
  (backup original libGL.so.1.2 to libGL.so.1.2.xgi.old)
  link libGL.so  and libGL.so.1 to libGL.so.1.2  (ln -s)
5.modify rc.modules  (backup original to rc.modules.xgi.old)
  which is under /etc in Red Hat distribution
           under /etc/rc.d in Mandrake distribution

  insmod /lib/modules/2.4.x/kernel/drivers/video/xgi/xgifb.o [mode=wxhxd] 
[rate=r] (ex. mode = 1024x768x16 rate=85)
  insmod /lib/modules/2.4.x/kernel/drivers/char/agp/agpgart.o
  insmod /lib/modules/2.4.x/kernel/drivers/char/drm/xgi.o

  if you don't want to modify rc.modules, you can run insmod by yourself
  
**if you don't want any specific step, just remove it from install.sh
