UEFI Driver Signing Adds policy around UEFI and its 3 rd party image extensibility – Admixture of OS loaders, apps, and drivers in system – Gives IT control around these executables – Detects/prevents malware Technology includes – Supports “known-good” and “known-bad” signature databases – Policy-based updates to list
You can also create namespaces in UEFI settings as follows: 1. Go to UEFI Setup System Settings Intel Optane DCPMMs Namespaces Create Namespace to create namespace for DCPMMs. 2. The allocated capacity needs to be set as zero to cover the whole region, see Figure 1. Figure 1 Create namespace for DCPMM in UEFI settings 3.
Consistent Configuration Infrastructure. The UEFI spec defines a methodology of describing the platform configuring data in a standard way. The rendering of the data is left to the platform vendor. This allows UEFI to bring all the platform configurations like BIOS, Storage and Network options under a
Studies have shown veterinary surgeons do not feel they receive adequate training in small animal nutrition during veterinary school. In a 1996 survey among veterinarians in the United States, 70% said their nutrition education was inadequate. 3. In a 2013 survey in the UK, 50% of 134 veterinarians felt their nutrition education in veterinary school was insufficient and a further 34% said it .
