setenv bootcmd $ramboot
5. Specify the name of the kernel image file:
setenv bootfile
6. Enter saveenv, and then enter boot.
5.3.3 Configuring U-Boot to Boot from Flash
The blade provides two redundant boot flashes which contain the U-boot images and also
Linux kernel images. It also contains two redundant root file systems.
This section describes how to configure U-boot to boot a Linux kernel stored in the boot flash
and to mount the root file system in the user flash. The procedure uses the U-Boot script
flashboot, which has been predefined by Artesyn Embedded Technologies.
1. Configure U-boot to boot from flash:
setenv bootcmd $flashboot
2. Depending on your system configuration, you may want to specify network
parameters as follows:
setenv ipaddr
setenv serverip
setenv netmask
setenv gatewayip
3. Enter saveenv, and then enter boot.
5.4 Selecting the Boot Flashes
This configuration determines which flash the blade is to boot from on the next restart. You can
either boot through IPMI or through a U-Boot command.
 Using IPMI - This option uses the System Boot Options feature. For more information, see
the ATCAF125: Control using IPMI Programmer’s Reference.
 Using U-Boot command - Use bootsel 0|1|switch, where 0 selects boot flash 0, 1
selects boot flash 1 and switch selects the currently stand-by boot flash.
