I have only played with the boot/pc version, and I only know that it initialises without panic, but I'm a lot more confident of being able to use it now. I did go to a lot of trouble to make "etherpcnet.c" as general as possible, but I can only test it for the 97c960 as I have no access to any other controller (I suppose I can try the VMware emulation, but that strikes me as asking for trouble). If anyone is interested, I'll clean up the code a bit and then post the driver on my web site. I really would like some review (it's a merge of a driver from forsyth and the release version) before I tackle the 9/pc alternative and then have to duplicate all the error corrections :-) Mail me if you'd prefer a copy by e-mail. One item I have not understood at all in my quest for information is Plan 9's use of bounce buffers when using DMA in a 24-bit environment. Could someone familiar with this topic point me to the pertinent information or source code? ++L
