Struct smbioslib::SMBiosBisEntryPoint

pub struct SMBiosBisEntryPoint<'a> { /* fields omitted */ }

Boot Integrity Services (BIS) (Type 31)

Structure is reserved for use by the Boot Integrity Services (BIS)

This class is compliant with: Boot Integrity Services Application Programming Interface Version 1.0 with added corrigenda: bis037 Published August 31, 1999

Note: The BIS (Boot Integrity Services) Entry Point structure is not defined in the SMBIOS DMTF document. bisapi037.pdf, section 3.1.3 typedef struct _BIS_ENTRY_POINT

Implementations

impl<'a> SMBiosBisEntryPoint<'a>

pub fn checksum(&self) -> Option<u8>

Used to make the 8-bit checksum of this structure equal zero.

pub fn bis_entry_16(&self) -> Option<u32>

BIS entry point pointer for use by 16-bit real-mode callers. This is a segmented pointer(in segment:offset form).

Real Mode: In Real Mode all addresses are composed of Segment:Offset pairs, with both Segment and Offset being 16 bits.These combine to form a 20-bit physical address that cannot access above approximately the 1 Megabyte boundary.This mode is referred to in this section as “16-bit real-mode” or “16-bit mode”. Callers in this mode may only invoke BIS through the bisEntry16 entry point. The bisEntry16 function returns with the processor in 16-bit real-mode.

pub fn bis_entry_32(&self) -> Option<u32>

BIS entry point pointer for use by 32-bit flat physical address mode callers. This is a 32-bit physical address.

Flat Mode: A 32-bit (protected) IA-32 processor mode where CS:0, DS:0, and SS:0 all refer to physical location 0 and all have 4 GB of address space.This mode is referred to in this section as “32-bit flat-mode” or “32-bit mode”. Callers in this mode may only invoke BIS through the bisEntry32 entry point. The bisEntry32 function returns with the processor in 32-bit flat-mode.
