Providing Linux Kernel and initial ramdisk
To provide Linux kernel and initial ramdisk, proceed as follows:
1. Copy the pxelinux bootloader to the /tftpboot directory.
2. Create a blade specific directory, e.g. /tftpboot/<board-dir>, and copy the
Linux kernel and the initial ramdisk for the boards to this directory.
3. Create a directory /tftpboot/pxelinux.cfg. Change to this directory and
create a file named default.<boardname> which will contain the board specific
boot line parameters, for example,
/tftpboot/pxelinux.cfg/default.ATCA7150 DEFAULT <board-
dir>/kernel ramdisk_size=... console=ttyS0,<baudrate>
initrd=<board-dir>/ramdisk.image.gz root=/dev/ram0 ip=none
rw ...
4. In the /tftpboot/pxelinux.cfg directory, create a softlink for the blade's
MAC address to the default.<boardname> file:
ln –s default.<boardname> <MAC address with leading 01 and
"–" as delimiter>
