	readme.txt		- (This file)The readme file for ARC11XX/ARC12XX Linux scsi raid driver  
 	arcmsr.1.20.0x.15.zip	- Source code (arcmsr.c, arcmsr.h, Makefile)

**********************************************************************
** 2. First time Installation                          **
**********************************************************************
	A. Before Installation - Under DOS/Windows environment

		a. Unzip "install.zip"
			X:\PATH\pkunzip.exe install.zip =>> driver.img
		b. Dump it into a floppy disk.
			X:\PATH\rawrite.exe driver.img A:
		Tips: You can get rawrite.exe from S.u.S.E. Installation CD1 or DVD 

	B. S.u.S.E Linux installation start...boot from CD or DVD

		a. Press "F3" to choose Other Options.

		b. Press "F5" to install a Driver Disk.

		c. Select "Installation ---" to install the SuSE Linux

		d. Insert the driver disk to floppy drive.

		e. When "Please Choose the Driver Update medium" pop-up, press "back" for back to installation console.

		f. Follow SuSE installion procedure to finish your system installation.

	P.S. : Once you updated kernel version to a new one. 
		you will need to boot up from old kernel, 
		and make a driver module for new kernel first.


**********************************************************************
** 3. Installing raid driver on an Existing System.                 **
**********************************************************************
CASE 1: if you do not attempt to compile driver source

	Insert the driver disk to floppy drive.
	# mount /media/floppy
	# cd /media/floppy
	# sh patch
	# cd /
	# umount /media/floppy
	# reboot

CASE 2: if you need to compile linux kernel drivers source
	(You must install your Linux system with development environment first.)

	A. Prepare for make new kernel and drivers

		a. After kernel source installed, you need create a short link 'linux' in /usr/src directory first.

			#ln -s linux-2.6.x linux

		b. Unzip arcmsr.1.20.0x.15.zip

		c. Depended on your kernel version, copy the properly folder (arcmsr) to /usr/src/linux/drivers/scsi

	B. Modify make and config files 

		In /usr/src/linux/drivers/scsi/Makefile
			@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
			@ ...
			@ ....
			@ obj-$(CONFIG_SCSI_ARCMSR)	+= arcmsr/
			@ ...
			@ ..
			@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@

		In /usr/src/linux/drivers/scsi/Kconfig
			@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
			@ ...
			@ ....
			@ config SCSI_ARCMSR
			@ tristate "ARECA ARC11X0[PCI-X]/ARC12X0[PCI-EXPRESS] SATA-RAID support"
			@ depends on PCI && SCSI
			@ help
			@ This driver supports all of ARECA's SATA RAID controllers cards.
			@ This is an ARECA maintained driver by Erich Chen.
			@ <If you have any problems, please mail to: erich@areca.com.tw >.
			@
			@ To compile this driver as a module, choose M here: the
			@ module will be called arcmsr (modprobe arcmsr) .
			@ ....
			@ ...
			@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@

	C. Make new kernel

		# cd /usr/src/linux
		# make mrproper
		# make config (or make xconfig ,make gconfig ,make menuconfig)
			Tips: Say "M" means configure this driver as a module.
		;You can load default config from /boot/config-2.6.16.13-4-smp ....
		;When prompt for "SCSI support" say "Y" or "M".
		;When prompt for "SCSI disk support" say "Y" or "M".
		;When prompt for "SCSI tape support" say "Y" or "M".
		;When prompt for "SCSI CD-ROM support" say "Y" or "M".
		;When prompt for "SCSI generic support" say "Y" or "M".
		;When prompt for "ARECA ARC11X0[PCI-X]/ARC12X0[PCI-EXPRESS] SATA-RAID support" 
			;say "Y" or "M"

		# make dep
		# make clean
		# make bzImage
		# make modules 
		# make modules_install

		; if your system is x86_64 and not SMP
		# cp -f ./arch/x86_64/boot/bzImage   /boot/vmlinuz-2.6.16.13-4-default

		; if your system is x86_64 and SMP
		# cp -f ./arch/x86_64/boot/bzImage   /boot/vmlinuz-2.6.16.13-4-smp

		; if your system is i386 and not SMP
		# cp -f ./arch/i386/boot/bzImage   /boot/vmlinuz-2.6.16.13-4-default

		; if your system is i386 and SMP
		# cp -f ./arch/i386/boot/bzImage   /boot/vmlinuz-2.6.16.13-4-smp


	D. Make an initrd image

		NOTICE: If your low-level drivers are module, go through, otherwise, skip.  

		An initrd image is needed for loading your SCSI module at boot time.
		So you need make your own initrd image.....

		Edit file /etc/sysconfig/kernel
			###############################################################################
			..
			...
			INITRD_MODULES="arcmsr reiserfs"           # add this context description
			...
			..
			===============================================================================

		#mkinitrd
		#reboot

	P.S: If you don't overwrite default kernel.
	You can edit /boot/grub/menu.lst and do your own kernel and ramdisk image in case that you have made incorrect kernel.
