Which SMC card? Any card based on the DC21x4x series of PCI Ethernet Controllers will have no onboard buffering other than the "relatively" small FIFOs on the chip itself. Instead, the DC21x4x chips DMA directly to/from host memory which allow as much buffering as one wants. -- Matt Thomas Internet: matt@lkg.dec.com U*X Networking WWW URL: <pending> Digital Equipment Corporation Disclaimer: This message reflects my Littleton, MA own warped views, etc.
