Additional information
====================

 1. megaraid-1.19.4-1.i386.rpm

You can use
              a.   rpm -e "name of RPM" to uninstall
              b.   rpm -q  "name of RPM" to query RPM.

This is the  binary  RPM  containing  the 1.18f  driver  for  Redhat.  
The megaraid.o driver is installed in the appropriate scsi directory  
depending on if an SMP or uniprocessor installation was done.

This RPM can be used to install or remove the 1.18f  driver.  Please 
note that this RPM has an  additional  feature,  whereby it creates a 
new RAMDISK image after updating the megaraid.o driver.

NOTE:

1.  'dialog'  utility  must  be  installed  on the  system  before  
attempting installation  of the  driver.  In case it is not  installed,  
the script  will attempt to install it from the package which is bundled 
with this release

This script also optionally run in X with 'real' GUI. The script will 
detectthe appropriate setting and launch the environment accordingly.


 The user must use the associated  wrapper  script  
"megarpmwrapper.sh" to install the RPM package.  The wrapper script 
installs the RPM package and does the post installation processing.

The script gives the default  command line to install the RPM  package,  
which can be altered by the user.  Then this command line is used to 
install the RPM package.

The script then gives the user three options to do the postinstallation 
steps:

i.	Everything is done by the script itself. It includes:

	a. making new initrd ramdisk

	b.The user is then prompted to choose a new default lilo label

	c.  modifying the  /etc/lilo.conf  file.  The logic used to modify 
      the /etc/lilo.conf  file is to find out the  previous  default  
      label  and figure out which section has it.

	This section is used to make a new section with new default label 
      and new ramdisk.  All other entries remain same as the old section.

	The original /etc/lilo.conf is stored as /etc/lilo.org

	d. running the /sbin/lilo command

	e. reboot the machine
	
	Steps c and d are only performed if lilo is the bootloader. In 
      case of grub, user is prompted to edit /etc/grub.conf file.

ii.  The other option is:  scripts gives a series of instructions to 
the user, the actual  commands  have to be  completed  by himself - 
either  manually  or prompting the installation process to do so.

iii.  The  installation  process just creates the initrd  ramdisk, the 
      rest of the  things  have to done by the  user  all by  himself.  
      This  option  is for advanced users.


2. megaraid-1.19.4-1.src.rpm

This is the SOURCE RPM.  It installs only the  megaraid.c  and  
megaraid.h components to the /usr/src/redhat/SOURCES directory.


3. megaraid-1194.spec

This file is the specification  file for creating the binary RPM for
1.18f driver.

4. megarpmwrapper.sh 
Wrapper script for installing the driver This script can optionally run 
in the X environment. It detects the enviornment and launches the appropriate 
interface automatically. To enable this script to launch X interface, run it 
from the graphical screen. Script uses the text based GUI on console screens.
