RB532 boot problems

Hello
When i boot the rb532 it hangs up in booter 1.? beta and then nothing .
Propably something is not good with the bios.
How can i make an upgrade of the board firmware ?
You have in support the firmware but not the way of upgrade .
Also i have the blue led always on and the orange flashing.

Help please

If i put one CF on board with the 2.9.6 MT version ,you thing that RB will boot ?
As i say in terminal console the bios stays in “Routerboard 532 booter…” and nothing else.Not even the cpu frequency.
