However – you gave me an idea – to try to find the driver files in the vmware vmtools install. Works for me too!! This means you should be able use the original bit software on these members of the PCnet family of single-chip Ethernet controllers. Your way works perfect for me on three Windows NT 4. This section possibly contains original research.

You can not post a blank message. The card maintains separate pointers internally. Go to original post.

But the “Table B Each of these then contains a pointer to the actual physical address of the memory used for the packet. Retrieved from ” https: In this article we will use the latter. You should also have a variable that stores the current ‘pointer’ into each buffer i.

I was hoping that installing vmtools would automatically create the virtual PCnet ethernet adapter. After you have properly handled an interrupt, you will need to write a 1 back to the appropriate bit in CSR0 or CSR4 before sending EOI to ethenet interrupt controller or the interrupt will continue to be signalled. Retrieved from ” https: It will automatically install drivers and says to restart the os.

Will poll computer memory every 1.

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 card uses two ring buffers to store packets: After you import a Windows NT4 virtual machine, install a new virtual.

From Wikipedia, the free encyclopedia. I see this problem mentioned in one of the vmware docs: Archived from the original on A further important register exists in the IO space called the reset register. C chips have a bug which causes garbage to be inserted in front of the received packet. Do not be deterred! You need to parse ACPI tables etc.

Once all the control registers are set up, you adm bit 0 of CSR0, and then wait for initialization to be done. In other languages Deutsch. Etheret has built-in support for CRC checks and can automatically pad etherneh packets to the minimum Ethernet length. Views Read View source View history. See the spec description of CSR15 for further details. And this chip bug might be the reason. I have an old Windows NT4 partition that I wanted to set up as a virtual machine.

Actually I tried it twice – once with the path F: If you want to keep the current one, you will need to first read it from the EPROM of the card it is exposed as the first 6 bytes of the IO space that the registers are in.

This article will focus on the Am79CA a. There are other bits in CSR0 than can be set depending on how you set up interrupt masks in CSR3 and additionally other bits in CSR4 that can signal interrupts although these are usually masked out on reset.
