Hi,

I'm trying to install BSD 3.5 from official CDs distrib
on a "Nec Powermate CT" Box.
The computer reboot by itself befor the end of the install,
few time after the network start :-(
He not alwais crash at the same moment of the process install,
somtime just after the network interface start, somtime (when I
do it faster) during the package copy...
I try to change network cards from 3Com 3C905C-TX-M to Intel
PRO 100 cards without success.
I update the BIOS with latest Nec's V2.32 (Mother board MS 6309)
But it's same !
The computer work fine with Windows XP, but I want to use a real
OS :-)

This is the dmesg output :
