Then you've configured the memory location and size? Do you see what I am getting at here? When you setup the card (3c507.exe) you set the IRQ, memory location, and memory size. Therefore, you know what the setting are to dump into the kernel setup. Before we both get frustrated with each other: 1. Find and locate a copy of MSD.EXE. 2. Move it to the machine (or for BSD-only boxen, on a MS-DOS floppy). 3. Boot MS-DOS. 4. Run MSD.EXE. 5. Press "M" for Memory. 6. You should now be looking at a visual map of your memory. Any of the black areas (don't you _dare_ tell me you have a monochrome monitor. :-) can be used by the 3c507 as a buffer for data. 7. Exit MSD when you feel you have the appropriate information etched into your short-term memory, or a convient piece of dried wood mulch. 8. Run 3C507.EXE 9. Configure the card with the necessary information. 10. Reboot into FreeBSD. 11. Quick! kernel -cs. 12. Enter the appropriate information into the ie0 device (is that right?). 14. There is no step 13. :-) 15. It _should_ find the card. 16. When you have a shell prompt type: "fsck -p" and after that (Press `Enter' between them) "mount -a" (and press it after them :-). 17. Edit /etc/rc.conf to include "ie0" in the network_interfaces line. 18. Add a ifconfig_ie0 line with the ip, etc. 19. If you're running DHCP, you should read the docs on it. 20. If everything looks ok, hit "CTRL-D" and the machine should boot multi-user. The 3c507 works by buffering the incoming ethernet data into system RAM. Generally, (according to 3Com) the more space the better. > Anyone know of a good book or online docs that explain this kind of thing?

I'd go on 8K chunks. But machines have nasty tendencies to hang, and you programmed the card, you're _supposed_ to have the info. :-) But if you don't mind rebooting several times... PS: If you want to flame me, don't CC: the list. <http://mars.cs.uah.edu/cs/students/kkirby/3c507.exe>; -- Kris Kirby UAH Mail <kirbyk@email.uah.edu> UAH CS <kkirby@cs.uah.edu> Home <kris@airnet.net> WWW <nomurphy@hotmail.com> ------------------------------------------- TGIFreeBSD...
