[ECOS] debug i386 application

[dpalmer@tootbee.com]

Hello Muna,

You have to make sure that you are using an ethernet card 
that is based on the 82559 from Intel.  This is the 
Ethernet Pro 10/100+, some of the Ethernet Pro 100s and 
10/100s are based on the 82558/B Chipset and these will 
not work correctly.
