Ok, no tagged kernel. :) Thanks. Oh, I'm using a laptop, it has boot
from NIC and it works, but the problem with that is it says img is to
large for low memory. So that's why I went to etherboot.
1) here's the dhcp.conf lines (etherboot reports getting an IP):
host bailey {
hardware ethernet 00:0b:db:13:90:ab;
fixed-address 192.168.100.200;
next-server 192.168.100.105;
filename "kernel.diskless";
option root-path "192.168.100.105:/diskless_root";
}
2) Options for etherboot? I just typed make in /usr/ports/net/etherboot
without any options.
3) I used tftpd to get the kernel. tftpd is /tftpboot
This I finally figured out when I kept getting file not found errors.
hehehe. So I just tftp'd to the localhost and doh! it was right, file
wasn't found. I had the wrong path all over the place.
