Thanks for the quick reply. I found the network.c driver code in the
snapshot under i386ex bsp. The code refers to a "uti" board/nic. Is the
driver really for a specific card and, if so, who makes this card? (I found
nothing seaching the net.) FYI, on my potential RTEMS project, my 82596
ethernet controller is wired directly to the 80386 processor -- I have no
expansion card slots.
