Field Documentation

UINT8_t s_PXENV::Signature[6]

Signature.

Contains the bytes 'P', 'X', 'E', 'N', 'V', '+'.

Definition at line 72 of file pxe_api.h.

UINT16_t s_PXENV::Version

PXE API version.

MSB is major version number, LSB is minor version number. If the API version number is 0x0201 or greater, the !PXE structure pointed to by PXEPtr should be used instead of this data structure.

Definition at line 80 of file pxe_api.h.

UINT8_t s_PXENV::Length

Length of this structure.

Definition at line 81 of file pxe_api.h.

UINT8_t s_PXENV::Checksum

Checksum.

The byte checksum of this structure (using the length in Length) must be zero.

Definition at line 87 of file pxe_api.h.

SEGOFF16_t s_PXENV::RMEntry

Real-mode PXENV+ entry point.

Definition at line 88 of file pxe_api.h.

UINT32_t s_PXENV::PMOffset

Protected-mode PXENV+ entry point offset.

PXE 2.1 deprecates this entry point. For protected-mode API calls, use the !PXE structure pointed to by PXEPtr instead.

Definition at line 95 of file pxe_api.h.

SEGSEL_t s_PXENV::PMSelector

Protected-mode PXENV+ entry point segment selector.

PXE 2.1 deprecates this entry point. For protected-mode API calls, use the !PXE structure pointed to by PXEPtr instead.

Definition at line 102 of file pxe_api.h.

SEGSEL_t s_PXENV::StackSeg

Stack segment selector.

Definition at line 103 of file pxe_api.h.

UINT16_t s_PXENV::StackSize

Stack segment size.

Definition at line 104 of file pxe_api.h.

SEGSEL_t s_PXENV::BC_CodeSeg

Base-code code segment selector.

Definition at line 105 of file pxe_api.h.

UINT16_t s_PXENV::BC_CodeSize

Base-code code segment size.

Definition at line 106 of file pxe_api.h.

SEGSEL_t s_PXENV::BC_DataSeg

Base-code data segment selector.

Definition at line 107 of file pxe_api.h.

UINT16_t s_PXENV::BC_DataSize

Base-code data segment size.

Definition at line 108 of file pxe_api.h.

SEGSEL_t s_PXENV::UNDIDataSeg

UNDI data segment selector.

Definition at line 109 of file pxe_api.h.

UINT16_t s_PXENV::UNDIDataSize

UNDI data segment size.

Definition at line 110 of file pxe_api.h.

SEGSEL_t s_PXENV::UNDICodeSeg

UNDI code segment selector.

Definition at line 111 of file pxe_api.h.

UINT16_t s_PXENV::UNDICodeSize

UNDI code segment size.

Definition at line 112 of file pxe_api.h.

SEGOFF16_t s_PXENV::PXEPtr

Address of the !PXE structure.

This field is present only if Version is 0x0201 or greater. If present, it points to a struct s_PXE.
