SunFire x4450 FIRMWARE

Hi. I have an older server, which still works well, but we urgently need to do firmware upgrade. To download firmware Sunfire x4450 I need a "Support Identifier". Support costs $ 1000... That server is no longer worth the money as they want for support...

And the question is - does anyone have a firmware for this server?

On my server is installed SP 4.08, BIOS vers. 3B09
