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. Change to the Network Adapters screen by clicking the Adapters tab. I was struggling for this issue since weeks. Is it somewhere buried in the vmware distrib and I could get it off that? You will need to allocate a 28 byte region of physical memory, aligned on a bit boundary. Personal tools Log in.

You should also have a variable that stores the current ‘pointer’ into each buffer i. INF not found”, and then with the path F: Works for me too!!
During normal initialization and use of the cards, the CSRs are used exclusively.

Your advice helped alot. After you import wmd Windows NT4 virtual machine, install a new virtual. MODE provides various functions to control how the card works with regards to sending and receiving packets, and running loopback tests.
Depending on your design this may be preferable. Go to original post.
We simply fail and return. Note that interrupts can come from many sources other than new packets.
Each of these then contains a pointer to the actual physical address of the memory used for the packet. Thanks for the detailed instructions. 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.
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. 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. You probably want this as it is far easier to poll for this situation which only occurs once anyway.

Shut down Windows NT and power off the virtual machine. The card maintains separate pointers internally. There are two ways of setting up the card registers: Just need to run VMWare Tools. 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 you interrupt controller or the interrupt will continue aamd be signalled.
Yes, I did try that and it didn’t work.
