9. To boot the new U-Boot, reset the blade.
protect off 2:252-258
addresses to the currently stand-by U-Boot bank, while
protect off 1:252-258
addresses the currently active U-Boot bank.
The currently stand-by U-boot bank is always mapped to the start address
0xE2000000, while the currently active U-boot bank is always mapped to
0xE0000000.
If you wish to set a particular U-boot bank into the active state, then you need to set
the System Boot Options Parameter #96 (bit 0) appropriately and reboot. If this bit is
set to 0, then U-boot bank 1 will be active after the next reboot. If the bit is set to 1,
then U-boot bank 2 will be active. Note that depending on the blade’s IPMI firmware
version, the switch between the U-boot banks may be effective immediately.
