This page has been accessed 13, times. So I’ll ask again: Also the topic name “Who can help me” is itself not very helpful. You also need a simple way of incrementing the pointer and wrapping back to the start if necessary. This page was last edited on 17 April , at 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.

But once I updates the driver ,the system always reports failure. If you have trouble finding the vbox file, remember that Windows has an annoying pcnnet of hiding file extensions, a dangerous and confusing feature which I encourage you to turn off.
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.
You should also have a pcj that stores the current ‘pointer’ into each buffer i.
Will poll computer memory every 1. A further important register exists in the IO space called the reset register. And you may want to set bit 11 of CSR4 which automatically pads Ethernet packets which are too short to be at pccnet 64 bytes.
If it is set, it means the card owns it and the driver should not touch the entire entry. Each of these then contains a pointer to the actual physical address of the memory used for the packet. Statements consisting only of original research should be removed. You probably want this as it is far easier to poll for this situation which only occurs once anyway. Please improve it by verifying the claims made and adding inline citations. MODE provides various functions to control how the card works with regards to sending and receiving packets, and running loopback tests.
I particularly would have like to know what guest OS we’re talking about. But the “Table B This section possibly contains original research.
Finally, once all our ring buffers are set up, we need to give their addresses to the card. They have created another post HERE and what is causing the confusion.
This page was last modified on 11 Juneat You also need to specify the physical address MAC address you want the card to use. Views Read View source View history. My guest OS is win7 x64 and the virtualbox additions has been installed. Why are you in the belief that your Win7 VM needs specific obsolete network cards?
Depending on your design this may be preferable. Any help will be appreciated. The intel adapters built-in pdi work properly but the PCnet and PCfast can not work. I have found a strange phenomenon that there is an exclamation mark in device manager of the guest OS.
If you want to continue this conversation then please read: You will need to allocate a 28 byte region of physical memory, aligned on a bit boundary. Note that interrupts can come from many sources other than new packets. When I try to use some softwares used for discovering components and installing drivers automatically ,it always reports failuer pcnett it can not find the Ethernet Controller. From Wikipedia, the free encyclopedia. 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.
Where to get network drivers? External loopback on a live network may cause reception of invalid loopback failure indications.
