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: mem 0xfe000000-0xfe3fffff irq 11 at device 8.0 on pci1 en0: unexpected timeout in rx DMA test en0: WARNING: DMA test detects a broken PCI chipset! trying to work around the problem... but if this doesn't work for you, you'd better switch to a newer motherboard. en0: ATM midway v0, board IDs 6.0, Utopia (pipelined), 512KB on-board RAM en0: maximum DMA burst length = 64 bytes (must align) en0: 7 32KB receive buffers, 8 32KB transmit buffers allocated en0: End Station Identifier (mac address) 00:20:ea:0c:1f:ba en0: driver is using old-style compatability shims At 08:46 AM 1/16/01 -0800, Richard Hodges wrote: >On Tue, 16 Jan 2001, Mike Tancsa wrote: > > > I am about to try CLIP using the Efficient OC-3 card under 4.x.

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. ---Mike To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-atm" in the body of the message
