HP Proliant ML350 G5 BIOS

Hello,

I need to update BIOS on an old ML350 G5 which is not in production and usupported.

https://support.hpe.com/hpsc/swd/public/detail?swItemId=MTX-b80e134db9c14414b49e2e03de#tab-history

As HPE does not provide updates for their servers without payment is someone know which contract is required (if still available for an old server) to be allowed to download and update the BIOS ?

Thank you in advance.

Kind Regards
