I was hoping that installing vmtools would automatically create the virtual PCnet ethernet adapter. Please improve it by verifying the claims made and adding inline citations. The card regularly scans all the transmit buffers looking for one it hasn’t sent, and then will transmit those it finds. If a new packet has been signalled then CSR0 bit 10 will be set. The card uses two ring buffers to store packets:

It will automatically install drivers and says to restart the os. In other languages Deutsch. Just need to run Ame Tools. Networking hardware Integrated circuits. During normal initialization and use of the cards, the CSRs are used exclusively.

Shut down Windows NT and power off the virtual machine. MODE provides various functions to control how the card works with regards to sending and receiving packets, and running loopback tests. This means you should be able use the original bit software on these members of the PCnet family of single-chip Ethernet controllers.


No capability for transmit buffer byte count of zero. We simply fail and return. Receiving packets is normally done in your interrupt handler – the card will signal xmd interrupt whenever it receives a packet and has written it to the receive buffer. Yes, I did try that and it didn’t work. In this article we will use the latter.

Amx was struggling for this issue since weeks. Pnet I could get from you? This means that the index of the register you wish to access is first written to an index port, followed by either writing a new value to or reading the old value from a data register.

This article will focus on the Am79CA a. The next section will enable some interrupts on the card.

Your advice helped alot. These differences are not likely to require modifications of any device driver. It really worked for me as well. And you may want to set bit 11 of CSR4 which automatically pads Ethernet packets which are too short to be at least 64 bytes. The workaround is to ignore packets with an invalid destination address garbage will usually not match.


Finally, once all our ring buffers are set up, we need to give their addresses to the card. There are two ways of setting up the card registers: Works for me too!!


After you have pcnst handled an interrupt, you will need to write a 1 back to the appropriate bit in CSR0 or CSR4 before sending EOI to you interrupt controller or the interrupt will continue to be signalled.
