- I have been trying to get an SMC Elite16 card to work with the tcpip code
- in linux, the card works fine in a 386/40 but in my 486/33 it always
- reads rubbish from the card. The card works with PCNFS under dos so I can't
- believe there is any memory contension, and the same card and kernel work
- in the 386 so it can't be wrong configuration.
-
- The only explanation I have been given is that I have a 256K external cache,
- and although I can disable it in the bios it is still caching the card's
- address space. Does this sound possible? Is there anyway to force the
- address range to be not cached? Any other possible explanations?
- Does BSD do anything to avoid such problems?
-
- Thanks in advance,
-
