First draft of this document Planned releases: Write the Driver Transmit Task 3. Currently, this tool does not support the DEC board. Alternatively, the chip can be programmed to poll for the next available transmit descriptor if the transmit engine is in idle state. Network Driver Makefile 3.

If memory base is specified as NONE -1the driver ignores this parameter. To achieve it, we have chosen a Motorola MCP board. If this is specified as Intfl -1 then the default of 64 is used.

If the string is allocated but not empty, this routine tries to load the device. The driver programs the chip to process the transmit and receive queues at the same priority. See below, for an explanation of each MII flag. Many Ethernet adapter cards use the Tulip chip. On Intel, the memory region cache management is available only if the paging unit is enabled.
Write the Driver Start Function. Write the Driver Interrupt Handler 3. One buffer has bytes, one descriptor has 16 bytes. If the parameter is not specified, this version returns NULL.

Transmission starts when the frame size within the transmit FIFO is larger than the treshold value. Write the Iintel Transmit Task 3. Application Programming Interface 4.
We use Netboot tool to load our development from a server to the target via an ethernet network. We choose to use only one buffer of bytes per descriptor.
Write the Driver Attach Function 3. If the cpu board hardware automatically swaps all the accesses to and from the PCI bus, then input and output byte stream need not be swapped.
This thread is also event driven. Then the driver itel an interrupt handler to the interrupt line driven by the Ethernet controller the only interrupt which will be treated is the receive interrupt and launches 2 threads: If the link status indicates failure, AUI interface is configured. On Intel target, the chip specific registers can be accessed via 2 methods: Current applicable release is 1.
Again, see the device hardware reference manual for details. We have 7 receive buffers and 1 transmit buffer, and for each, 1 descriptor: Increasing the 21140q of the heap 4. Finally, we will see what will be done for ChorusOs and Netboot environment. First version of this document. Early versions used National transcievers, but later versions are depopulated ZX boards.
It means that we will have to re-write some mechanisms of this driver.

The format of the parameter string is: The information listed below may be out of date. Command and Variable Index Index. Network Task Structure and Data Flow 3. It does not signify the end of the original ingel, but that the parameter is null. If any of the assumptions stated below are not true for your particular hardware, you need to modify the driver before it can operate correctly on your hardware.
