This method is for installing to a system with the uniprocessor 
kernel installed.  If you need SMP support, then you will need 
to recompile your kernel after installation.  Also note that 
this proceedure updates your kernel source tree so you can build 
your own kernel with this same support.

Note: This is not a supported proceedure and has not been tested 
by Compaq.  I have created this method for those who for some 
reason or other is unable to use a newer version of Linux.  If you 
do not have any requirements that specifically state you must use 
RedHat6.1, then I suggest you move to a newer and more supported 
version of Linux such as RH6.2 or RH7.0.

Before you begin these steps you should have already complted the 
steps needed to get your system ready to run linux.  This means 
running System Erase (which does erase everything on the system so 
don't do it if you have data on the system you need), then boot 
with the SmartStart and Support Software CD, choose to do a manual 
install of Linux.  The system will configure itself (will run SCU), 
will configure the array (will run ACU), then will create the system 
partition if your system supports it.  After all this, SmartStart 
will turn control back over to you and prompt you to remove any CD's 
and floppies and now for you to insert your Linux installation media.  
Now you are ready to complete the following proceedure.

1.) Boot from Compaq RH6.1 Boot disk 1 (SP10775.EXE OR SP10776.TAR - they
are both the exact same)
2.) Enter "expert" mode
      *Note: If your server has the Symbios 1510 Chipset you must 
      use a driver diskette (SP13120.EXE). When asked for a driver 
      diskette insert the disk available at 
      http://www.compaq.com/support/files/server/us/download/7723.html. 
      Proceed thru the install until asked "Do you have any special 
      device drivers loaded for your system. Would you like to load 
      some now?" choose yes and select SCSI then the "Symbios/NCR 
      53c8xx (1510 support)"
3.) Proceed normally to point when install asked what type of 
      install. i.e. "server....custom"
4.) Cntl-Alt-F2 to bash prompt.
5.) Remove the Compaq boot disk and insert the disk provided 
      (array.img) then run the following commands:

	mknod /tmp/fd0 b 2 0
	*Note: The above command can be omitted if a driver disk was 
          installed in step 3.
	mkdir /a_directory
	mount -t ext2 /tmp/fd0 /a_directory
	insmod /a_directory/cpqarray.o -f
	umount /tmp/fd0

6.) Ctrl-Alt-F7 (or Ctrl-Alt-F1 if in text install)
7.) Make sure to install:

	kernel-source-2.2.14-5.0.i386.rpm
	kernel-headers-2.2.14-5.0.i386.rpm
	kernel-doc-2.2.14-5.0.i386.rpm <---- Optional
	cpp-1.1.2-30.i386.rpm
	make-3.78.1-4.i386.rpm
	ncurses-5.0-11.i386.rpm
	ncurses-devel-5.0-11.i386.rpm
	glibc-2.1.3-15.i386.rpm
	glibc-devel-2.1.3-15.i386.rpm
	glibc-profile-2.1.3-15.i386.rpm <---- Optional
	egcs-1.1.2-30.i386.rpm
	egcs-g77-1.1.2-30.i386.rpm <---- Optional
	egcs-c++-1.1.2-30.i386.rpm <---- Optional
	egcs-objc-1.1.2-30.i386.rpm

    Most of the above packages will be installed if you 
    choose "kernel development".

8.) Proceed with normal install until the end (after copying files) 
      when asked to create boot disk.  Stop before creating 
      the boot disk.

9.) After the install but before clicking the final exit button. 
    Ctrl-Alt-F2 to bash prompt and execute the following commands.

	#Here we will work with the array.img floppy so 
	#leave it in the drive.

	/mnt/sysimage/usr/sbin/chroot /mnt/sysimage
	mount /dev/fd0 /mnt/floppy
	cp /mnt/floppy/cpqarray.o /lib/modules/2.2.12-20/block
	cp /mnt/floppy/cpqarray.[ch] /usr/src/linux/drivers/block
	umount /mnt/floppy
	
	#At this point we need the Compaq add in's
	#from the uniprocessor floppy which is Disk #3 from
	#SP10775.EXE or the floppy image labeled cpq-kflopy-up.img
	#from SP10776.TAR.

	#Insert the correct Compaq floppy now (disk #3 or cpq-kfloppy-up.img)

	mount /dev/fd0 /mnt/floppy
	cd /usr/src/linux
	/usr/bin/patch -p1
