SCore Linux Kernel Installation

SCore Kernel Installation from binary RPMs

To Install sources, issue the following commands:

	# cd /opt/score.work
	# rpm -U kernel-source-score-2.4.21-*.rpm

To install the kernel image, issue the following commands depending on your machine architecture:

For Pentium Pro and later Intel architectures

	# cd /opt/score.work
	# rpm -U kernel-2.4.21-*SCORE.i686.rpm
	# rpm -U kernel-smp-2.4.21-*SCORE.i686.rpm

For Pentium archictures

	# cd /opt/score.work
	# rpm -U kernel-2.4.21-*SCORE.i586.rpm
	# rpm -U kernel-smp-2.4.21-*SCORE.i586.rpm

For 386 and 486 archictures


	# cd /opt/score.work
	# rpm -U kernel-2.4.21-*SCORE.i386.rpm

/etc/lilo.conf

Edit the /etc/lilo.conf so that the SCore linux kernel is used. An example of the /etc/lilo.conf is shown below:

boot=/dev/hda
map=/boot/map
install=/boot/boot.b
prompt
timeout=50
message=/boot/message
linear
default=linux
image=/boot/vmlinuz-2.4.21-1SCOREsmp
        label=linux
        initrd=/boot/initrd-2.4.21-1SCOREsmp.img
        read-only
        root=/dev/hda5
image=/boot/vmlinuz-2.4.2-19
        label=linux-up
        initrd=/boot/initrd-2.4.21-1SCORE.img
        read-only
        root=/dev/hda5

Installing the bootloader
the lilo command must be issued as follows:
```
	# sync
	# lilo
```

Halt the system and install a Myrinet card, then reboot the system

	# /sbin/halt

If a Myrinet card has been installed, the following kernel messages will appear during the boot sequence:

Myrinet 9 revison(1) bus(0) iobase(e7000000) irq(c) vmem(d0800000)

Values depend on the version of the Myrinet card and the host system. To make sure the PM drivers have been installed, issue the following command:

	# dmesg | grep -i pm

You will see several messages. e.g.,

PM memory support
Register pm_memory as major(123)
pm[0]: clockval = 90449044, cpu = 403, delay = 0, board = 1, sram = 100000
pm[0]: 30 contexts using 3840K bytes of memory
Register pm as major(121)
PM/Ethernet: "$Id: pm_ethernet_dev.c,v 1.68 2001/02/24 12:48:14 s-sumi Exp$"
PM/Ethernet: register etherpm device as major(122)
pmshmem: version = $Id: pm_shmem.c,v 1.6 2000/09/25 12:42:28 kameyama Exp $
pmshmem_init: register pm_shmem as major(124)
etherpm0: 8 contexts using 2048K bytes of memory, maxunit=2, maxnodes=128.
etherpm0: Interrupt Reaping on eth0, irq 10

Be sure that the above procedures are performed on all hosts so that a new kernel is installed on all hosts.
