In X10DRi-T4+ motherboard, we are using a branded firmware version 8.50 dated 04/12/2017. Is this firmware based off of the redfish version 3.58 that is available as the latest firmware for the x10’s or an earlier version?
No. It 's not. Your OEM BIOS 8.50 is based on standard 3.50. It's nothing change except the logo.
