What ONE tool will update an HP Proliant DL 580 G4's BIOS, firmware, etc.?

I am **not** asking about how to update drivers in Windows. I want to update drivers in hardware (aka BIOS, firmware, RAID controller driver, etc.) Do you know of an HP equivalent of Dell's SUU CD to either run from Windows or boot from that will evaluate current versions and offer updates as needed? I am already aware that SmartStart is a CD used to deploy a server, but this one is already deployed; if you know how to get SmartStart to update a system without installing an OS, plz let me know how, but first, plz show me how to determine I need it. I've already been to HP.COM; I see links for BIOS and firmware, but those say "entitlement required", and this server's warranty has already expired, and there is no "care pack" bought by my company. Is there anything easy and singular out there that can answer all questions about this box and just 'get it done' as needed? Thx.

WINMSD reports BIOS is "HP P59, 9/8/2006", and SMBIOS is 2.3.
