- Danpex EW-2016 is an inexpensive (US$85.) allegedly WD8013-compatible
- ethernet card. I was wondering if anyone has gotten 386BSD to
- recognize it, and if so, what configuration and jumper settings they
- used.
-
- First of all, I am assuming that the card should be recognized even if
- it is not connected to a network (my "network" is 2 computers, one of
- which is down...). Is this a reasonable assumption?
-
- Second, the card does not support IRQ 2 (so much for compatibility...),
- so I tried IRQ 9 and IRQ 15 and reconfigured the kernel accordingly, to
- no avail.
-
- But it is not clear what "iomem" should be. The default for we0 is
- 0xd0000. I presume this corresponds to the "RAM buffer base address"
- jumper setting on the EW-2016. If so, these addresses appear to be
- tied to specific interrupt values. For IRQ 15, for instance, I/O
- (i.e., port) address 0x200 and iomem 0xdc00 (sic) are required. I
- tried iomem 0xdc000 too (with appropriate changes to the kernel), but
- this didn't work either. What are the implications, if any, of such
- small iomem values (i.e., 0xd000 as opposed to 0xd0000)?
-
- Finally, the default iosiz for we0 is 8K (8196). Does it matter that
- the EW-2016 RAM buffer size is 16K? I tried both iosiz 8196 and 16384
- to no avail.
-
- As I am completely in the dark on this, any direction would be greatly
- appreciated.
