It has built-in support for CRC checks and can automatically pad short packets to the minimum Ethernet length.
I was hoping that installing vmtools would automatically create the virtual PCnet ethernet adapter. Please enter a title. Sending packets involves simply writing the packet details to the next available transmit buffer, then flipping the ownership for the particular ring buffer entry to the card. The card maintains separate pointers internally.
INF – and it showed up in F: If this is cleared, it means the driver ‘owns’ that particular ring buffer entry. Note that your submission may not appear immediately on our site.
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. You also need to specify the physical address MAC address you want the card to use. Advertisements or commercial links. Your etgernet has been reported and will be reviewed by our staff.
There are other bits in CSR0 than can be set depending on how adaapter set up interrupt masks in CSR3 and additionally other bits in CSR4 that can signal interrupts although these are usually masked out on reset.
I see this problem mentioned in one of the vmware docs: Once all the control registers are set up, you set bit 0 of CSR0, and then wait for initialization to be done.

Thanks for the detailed instructions. Actually I tried it twice – once with the path F: You also need a simple way of incrementing the pointer and wrapping back to the start if necessary.
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. Just need to run VMWare Tools. Note that interrupts can come from many sources other than new packets. Is it somewhere buried efhernet the vmware distrib and I could get it off that?
