needs more work.

The 3c515 is an ISA 10/100 card with busmastering capability.
|
||||
The chipset is similar to that of the 3c905, with some changes to
|
||||
make it work with the more limited ISA bus address space. This card
|
||||
is not currently supported.

If there are multiple cards in the computer, they are searched for

The 3c579 EISA cards are searched for first -- they will be found

in EISA slot# order.
|

Next, the 3c509 ISA cards are searched -- they are found in increasing
|

ethernet address order.
