The card regularly scans all the transmit buffers looking for one it hasn’t sent, and then will transmit those it finds. I too will need to manually install the driver from AMD’s site. Your way works perfect for me on three Windows NT 4. This means you should be able use the original bit software on these members of the PCnet family of single-chip Ethernet controllers. Transmit interrupt mask – if set then an interrupt won’t be triggered when a packet has completed sending.

To actually set up the card registers, we provide it with the address of our initialization structure by writing the low bits of its address to CSR1 and the high bits to CSR2. We simply fail and return. You can do this by either waiting for an interrupt if you didn’t disable the initialization done interrupt in CSR3 or by akd until CSR0 bit 8 is set.

However – you gave me an idea – to try to find the driver files in the vmware vmtools install. If it is set, it means the card owns it and the driver should not touch the entire entry.

I have an old Windows NT4 partition that I wanted to set up as a virtual machine. Please improve it by verifying the claims made and adding inline citations.


It has built-in support for CRC checks and can automatically pad etherhet packets to the minimum Ethernet length.

The workaround is to ignore packets with an invalid destination address garbage will usually not match. LADR is the logical address filter you want the card to use when deciding to accept Ethernet packets with logical addressing. Works for me too!!

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 ethenet out on reset. 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. And this chip bug might be ammd reason.

That I could get from you? After you import a Windows NT4 virtual machine, install a new virtual.

Pcner advice helped alot. INF – and it showed up in F: You also need a simple way of incrementing the pointer and wrapping back to the start if necessary.

I see this problem mentioned in one of the vmware docs: You need to parse ACPI tables etc. Actually I tried it twice – once with the path F: In this article we will use the latter.

This page was last edited on 17 Aprilat Finally, once all our ring buffers are set up, we need to give their addresses to the card. If you do not wish to use logical addressing the defaultthen set these etjernet to zero.

Ethrrnet the spec description of CSR15 for further details. There are two ways of setting up the card registers: The card uses two ring buffers to store packets: You probably want this as it is far easier to poll ethrrnet this situation which only occurs once anyway.

Do not be deterred!
