Message-ID: <5fnntrg.alm@netcom.com> Date: Sat, 05 Sep 92 09:04:48 GMT Organization: Netcom - Online Communication Services (408 241-9760 guest) Lines: 29 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. -Andrew Moore <alm@netcom.com>
