Altos R360 F2 FAQ (Frequently Asked Questions)
9. Can Altos R360 F2 support BIOS Recovery when BIOS is corrupted unexpectedly during BIOS update?
ANSWER: Yes. ANSWER: ANSWER: ANSWER:
10. What's UEFI (Unified Extensible Firmware Interface)?
ANSWER: The first EFI (Extensible Firmware Interface) specification was completed in the late 1990s, and in ANSWER:
ANSWER: ANSWER:
2005 the Unified EFI Forum was formed to standardize and promote UEFI implementations.
In contrast to BIOS, UEFI defines a set of boot and runtime services that have standard syntax and semantics
for interfaces and data structures. This means that all UEFI implementations behave essentially the same way,
making it possible to test and develop standard drivers and applications. This greatly improves interoperability,
reduces the complexity of supporting new hardware, and helps computer manufacturers to update and
maintain firmware more rapidly.

11. What's the difference between EFI & UEFI?
ANSWER: The EFI 1.10 specification is contributed by Intel and Microsoft. Intel holds the copyright of EFI 1.10 ANSWER: ANSWER: ANSWER:
specification. The UEFI Forum evolves, extends, and adds new functionality required to produce UEFI 1.0
specification. All licensing for UEFI 1.0 specification will come from UEFI Forum.
12. What's the benefit of UEFI?
ANSWER: ANSWER: UEFI firmware provides several technical advantages: ANSWER: ANSWER:
OS Boot from GPT (GUID Partition Table)
•
UEFI supports a more flexible partitioning scheme based on GPT. GPT disks use 64-bit values to describe
partitions, which allow a maximum disk size of roughly 16.8 million TB and over 100 primary hard disk
partitions.
Provides a pre-boot execution environment (not an OS)
•
UEFI drivers and applications are designed to execute in the boot environment with very few constraints.
Therefore, UEFI can provide a full network stack with high-resolution graphics and access to all devices,
even if no functional operating system is available.
Removes the Upper Memory Block limit for Option ROM's
•
All UEFI implementations that conform to the UEFI specification include an EBC (EFI Byte Code)
interpreter. EBC images are option ROMs that are compatible across all processor architectures.
Additionally, because EBC images are highly compact and universally applicable, option ROMs in a PCI
card can be much smaller than on BIOS systems.
Compatibility with earlier BIOS
•
The systems with UEFI firmware can boot operating systems that are UEFI-capable and older operating
systems that support only BIOS.
13. What's EFI shell?
ANSWER: ANSWER: The EFI shell is a unique feature embedded in EFI firmware. Users can execute EFI commands in the ANSWER: ANSWER:
EFI Shell. The EFI shell works as a small OS.
NOTE. You could update BIOS in EFI shell. Please refer to Altos R360 F2 BIOS Release Note for more detail.
14. How do I enter EFI shell?
ANSWER: ANSWER: Please press F F F F 6 6 6 6 during POST. ANSWER: ANSWER:
You would see below options:
