Hi,
sorry for an incomplete messge just sent out by accident. The prob i
have met is:
I was compiling FreeBSD with a Myrinet interface and it comiled and
linked without any error message. but when I boot, at the network
inititalizatin phase, there is page fault somehow. seems it can see the
Myrinet card but the dirver(?) is not installed correctly. sicne it
doesn't give any error even warning, i have no idea where to look into.
The full boot mesg is follows;
Automatic reboot in progress...
/dev/rwd0a: clean, 532326 free (550 frags, 66472 blocks, 0.1%
fragmentation)
Doing initial network setup: hostname domain.

Rebooting...
If you can give me some direction on where to look for the probs, it
will be much apprecaited.
Thanks,
