C chips have a bug which causes garbage to be inserted in front of the received packet. Others may find this URL useful: If a new packet has been signalled then CSR0 bit 10 will be set. There are two ways of setting up the card registers: I’m working with Workstation 4 and unfortunately the windows.

Each of these then contains a pointer to the actual physical address of the memory used for the packet. During normal initialization and use of the cards, the CSRs are used exclusively. I see this problem mentioned in one of the vmware docs: This means that the index of the register you wish to access is first written to an index port, followed ehhernet either writing a new value to or reading the old value from a data register.

And this chip bug might be the reason. You can do this by either waiting for an interrupt if you didn’t disable the initialization done interrupt in CSR3 or by polling until CSR0 bit 8 is set. Please turn JavaScript back on and reload this page. Once all the control registers are set up, you set bit aamd of CSR0, and then wait for initialization to be done.


If networking was disabled at the time you installed Windows NT, you can enable it after installing amx operating system.

That I could pcne from you? Interrupt done mask – if set then you won’t get an interrupt when the card has finished initializing.

This page was last modified on 11 Juneat See the spec description of CSR15 for further details. 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.

Receive descriptor zero byte count buffer interpreted as available bytes. And you may want to set bit 11 of CSR4 which automatically pads Ethernet packets which are etherney short to be at least 64 bytes. INF – and it showed up in F: This page has been accessed 13, times.

Actually I tried it twice – once with the path F: There are two ways of setting up the card registers: 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.


Statements consisting only of original research should be removed. The next section will enable some interrupts on the card. Given that the MMIO pcneg is sometimes absent on emulators or certain systems, this article will focus on the IO port access. It has built-in support for CRC checks and can automatically pad short packets to the minimum Ethernet length.

You also need a simple way of incrementing the pointer and wrapping back am the start if necessary. LADR is the logical address filter you want the card to use when deciding to accept Ethernet packets with logical addressing. A further important register exists in the IO space called the reset register. You don’t have JavaScript enabled.

The workaround is to ignore packets with an invalid destination address garbage will usually not match. Works for me too!!

Note that interrupts can come from many sources other than new packets. Depending on your design this may be preferable.

MODE provides various functions to control how the card works with regards to sending and receiving packets, and running loopback tests. Yes, I did try that and it didn’t work.
