Thanks for the quick response! I have the card installed, but it seems to
be complaining about broken DMA. This is on an Intel 810e motherboard. I
ran the DOS diag util and according to it, all tests including the DMA
tests passed.
en0: <Efficient Networks ENI-155p> mem 0xfe000000-0xfe3fffff irq 11 at
device 8.0 on pci1
en0: unexpected timeout in rx DMA test

trying to work around the problem... but if this doesn't
work for you, you'd better switch to a newer motherboard.

Super. I will have a look through the archives for the patch.

This box will only have one function, to connect to my upstream on OC-3. I
ordered an IMC SM to MM media convertor that I will try out. The box will
only push about 30Mb/s through it as well as do BGP with the upstream
peer. Currently I am doing via ethernet on a slower box and it handles the
load just fine. Hopefully, the ATM card will do the trick as well.
