[SCore-users] pxe boot for EIT

[Nick Birkett]

Sorry my last mail was rejected because it was too big.

Please replace dummy vmlinuz and initrd.img by the ones from the EIT5 boot
floppy.

Hi, we have pxe boot working for EIT. Perhaps this can be incorporated in the 
next release as there are now budget priced compute servers that come
without floppy or cdrom ?

Method: Set up dhcpd server and tftp server, and make sure BIOS in compute 
node includes network boot. 

Compute node first obtains EIT vmlinuz and initrd.img from boot server (e.g
front end node). this then boots and rest  works  same as EIT5 with floppy.

The IP range for dhcp does not have to corresond to EIT IP range as long as 
they are on the same subnet.


Sample config files  are attached.

The file pxelinux.0 is taken from the latest pxelinux (part of  Syslinux 
package). 

Also there is a small bug in 

/mnt/cdrom/setup/config5/ndpostpro-skelton  

(on SCore 5.0.1 cdrom)

# Other local settings if you specify $INSTALL_PATH/etc/pcc-env.sh
#
if test -f $parameter(installPath)/setup/install/pcc-env.sh ; then
    $parameter(installPath)/setup/install/pcc-env.sh
fi
# 

should read (wrong Path) :

# Other local settings if you specify $INSTALL_PATH/etc/pcc-env.sh
#
if test -f $parameter(compInstallTmpPath)/setup/install/pcc-env.sh ; then
    $parameter(compInstallTmpPath)/setup/install/pcc-env.sh
fi
# 

Cheers,

Nick
