In this article we will use the latter. Finally, once all our ring buffers are set up, we need to give their addresses to the card. The card maintains separate pointers internally. Note that if you want to wait for an interrupt you will also need to set bit 6 of CSR0 or interrupts won’t be generated you will need to enable this anyway to get notification of received packets, so it makes sense to set it at the same time as the initialization bit. The card regularly scans all the transmit buffers looking for one it hasn’t sent, and then will transmit those it finds. Receiving packets is normally done in your interrupt handler – the card will signal an interrupt whenever it receives a packet and has written it to the receive buffer.

Network Adapters – AMD Inc. – AMD PCNET Family Ethernet Adapter (PCI) Computer Driver Updates
Your way works perfect for me on three Windows NT 4. In this article we will use the latter. This page was last modified on 11 Juneat Note that if you want to wait for an interrupt you will also need to set bit 6 of CSR0 or interrupts won’t be generated you will need to enable this anyway to get notification of received packets, so it makes sense to set it at the same time as the initialization bit.
I did so and everything went smoothly and I can boot it as a virtual machine – and installed vmtools – but there is no AMD PCnet Ethernet adapter present.
It will automatically install drivers and says to restart the os. That I could get from you? This content has been marked as final. The card maintains separate pointers internally.

Click Continue to finish installing the driver. Contents 1 Overview 2 Initialization and Register Access 2. Also I’m curious – on Win2K, where does vmtools get the adapter driver from?
At initialization, you would want the card to ‘own’ all the receive buffers so it can write new packets into them that it receives, then flip ownership to the driverand the driver to ‘own’ all the transmit buffers so it can write packets to be transmitted, then flip ownership to the driver. It really worked for me as well. This article will focus on the Am79CA a. The posting of advertisements, profanity, or personal attacks is prohibited.

See the a,d description of CSR15 for further details. You qmd also have a variable that stores the current ‘pointer’ into each buffer i. I tried this using two different sources for the adapter driver, and re-installing vmtools with “repair” option after each one, and neither worked:.
The card uses two ring buffers to store packets: If you do not wish to use logical addressing the defaultthen set these bytes to zero.

Interrupt done mask – if set then you won’t get an interrupt when the card has finished initializing. Flaming or offending other users.
Sending packets involves simply writing the packet details to the next available transmit buffer, then flipping the ownership for the particular ring buffer entry to the card.

pcmet Once initialization has completed, you can finally start the card. We will flesh out the interrupt handler later, but you should install the interrupt handler here as otherwise you will get crashes due to unhandled interrupts. 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.
