Altos R360 F2 FAQ (Frequently Asked Questions)
9. Can Altos R360 F2 support BIOS Recovery when BIOS is corrupted unexpectedly during BIOS update?
ANSW R:
ANSW R:ANSW R:
ANSW R: Yes.
10. What’s U FI (Unified xtensible Firmware Interface)?
ANSW R:
ANSW R:ANSW R:
ANSW R: The first FI ( xtensible Firmware Interface) specification was completed in the late 1990s, and in
2005 the Unified FI Forum was formed to standardize and promote U FI implementations.
In contrast to BIOS, U FI defines a set of boot and runtime services that have standard syntax and semantics
for interfaces and data structures. This means that all U FI 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 FI & U FI?
ANSW R:
ANSW R:ANSW R:
ANSW R: The FI 1.10 specification is contributed by Intel and Microsoft. Intel holds the copyright of FI 1.10
specification. The U FI Forum evolves, extends, and adds new functionality required to produce U FI 1.0
specification. All licensing for U FI 1.0 specification will come from U FI Forum.
12. What’s the benefit of U FI?
ANSW R:
ANSW R:ANSW R:
ANSW R: U FI firmware provides several technical advantages:
• OS Boot from GPT (GUID Partition Table)
U FI 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)
U FI drivers and applications are designed to execute in the boot environment with very few constraints.
Therefore, U FI 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 U FI implementations that conform to the U FI specification include an BC ( FI Byte Code)
interpreter. BC images are option ROMs that are compatible across all processor architectures.
Additionally, because BC 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 U FI firmware can boot operating systems that are U FI-capable and older operating
systems that support only BIOS.
13. What's FI shell?
ANSW R:
ANSW R:ANSW R:
ANSW R: The FI shell is a unique feature embedded in FI firmware. Users can execute FI commands in the
FI Shell. The FI shell works as a small OS.
NOT . You could update BIOS in FI shell. Please refer to Altos R360 F2 BIOS Release Note for more detail.
