Field Documentation

PXE_UINT8 s_pxe_cpb_initialize::DuplexMode

The following configuration parameters are optional and must be zero to use the default values.

PXE_UINT32 s_pxe_cpb_initialize::LinkSpeed

Desired link speed in Mbit/sec. Common ethernet values are 10, 100 and 1000. Setting a value of zero will auto-detect and/or use the default link speed (operation depends on UNDI/NIC functionality).

PXE_UINT8 s_pxe_cpb_initialize::LoopBackMode

PXE_UINT64 s_pxe_cpb_initialize::MemoryAddr

Address of first (lowest) byte of the memory buffer. This buffer must be in contiguous physical memory and cannot be swapped out. The UNDI will be using this for transmit and receive buffering.

PXE_UINT32 s_pxe_cpb_initialize::MemoryLength

MemoryLength must be greater than or equal to MemoryRequired returned by the Get Init Info command.

PXE_UINT16 s_pxe_cpb_initialize::RxBufCnt

PXE_UINT16 s_pxe_cpb_initialize::RxBufSize

PXE_UINT16 s_pxe_cpb_initialize::TxBufCnt

Suggested number and size of receive and transmit buffers to allocate. If MemoryAddr and MemoryLength are non-zero, this allocation comes out of the supplied memory buffer. If MemoryAddr and MemoryLength are zero, this allocation comes out of memory on the NIC.

If these fields are set to zero, the UNDI will allocate buffer counts and sizes as it sees fit.
