I will need also some help for testing it, as I do not have a Linux working install on my Amiga because I need hd-media initrd and network support :) I am able to boot a kernel with an initrd. > Doesn't print the ring buffer addresses - might need a patch to the BSD > source to do that (I haven't looked at BSD source in over 20 years).

I am afraid ifconfig doesn't print anything about the ring buffer, and -to my knowledge- there is not equivalent ethtool. > But what I meant is to check whether the ne driver source hard-codes the > ring buffer addresses for these cards? Maybe we can know by taking a look to the NetBSD driver source code? I think it is located on the following files: 1. Gayle PCMCIA driver [1]. 2. ne2000.c [2], ne2000reg.h [3], ne2000var.h [4] 3. dp8390reg.h [5], dp8390var.h [6] I don't have the needed knowledge about the NE2000 driver or the kernel, but to my untrained eye it doesn't look like there is anything hardcoded for these cards. > There's a patch of mine floating around that uses CIS data to figure out > 8 or 16 bit IO width (submitted to linux-m68k and netdev a while ago). > With that one applied, dumping the CIS data and hand-parsing the result > might be one way to obtain the necessary data. In [2] there is a function called ne2000_detect_8bit() that is used for that. It looks like it reads the card ROM to figure out. I don't know if the CIS is considered a ROM or not.
