i'm sorry for not being clear. what i specifically want to happen is
similar to what happens to windows. basically:

1. upon boot, check if i can get an address from dhcp.
2. if i can, great, get address, and done. if not...
3. automatically set an ip address that doesn't conflict with anything
else using apipa 169.254.x.x address range.

what currently happens is:

1. upon boot, check if i can get an address from dhcp.
2. if i can, great, get address, and done. if not, eth0 isn't brought
up, no ip address.

is there a way to set a default/"alternate" address in case i do not
get an ip address from the dhcp server? that way windows machines can
access me through my ip easily. any options i can put in
/etc/sysconfig/network-scripts/ifcfg-eth0, or maybe a man page i can
read about it, as i can't seem to find any help on options for the
ifcfg-ethx scripts.

thanks!
