Re: [SLUG] PCMCIA 10/100 card tuning?

I had no idea what kernel options to pass to this PC card since it doesn't have a real unique identifier but I used the "pcnet_cs" value I found. I tried all sorts of things to stop the card from auto-negotiation but it still comes up 100TX FD. I think I have one of those cards that cannot be changed by the current Linux. I would've gone through the source but I don't have room for it on the HDD. One of the things I tried was in /etc/pcmcia/network.opts and adding IF_PORT=10base2 to the config. It complained about an invalid ioctl. Further searching on the net indicated that this meant the card couldn't change the port speed. Surely there must be a way to change the port speed?! It's a 10/100 card, meaning there are 2 choices! I think the issue is that the driver in Linux doesn't know how to turn off auto-negotiation for this particular brand :( rachel -- Rachel PolanskisOptus/Excite@Home UNIX Administrator 100 Harris Street IT Operations Pyrmont, Sydney NSW [EMAIL PROTECTED]Ph: (+61 2) 900 51144 -- SLUG - Sydney Linux User Group Mailing List - http://slug.org.au/ More Info: http://lists.slug.org.au/listinfo/slug

append options to the kernel or to the module ;) Look in the kernel source ;) Dean Rachel Polanskis wrote: > On Mon, 25 Jun 2001, Dean Hamstead wrote: > > >>Check your duplex setting, seeing as you have a dumb hub >>you might need to force 10mbps/half-duplex >> >>Your symptoms sound like your at full duplex. >> > > Yes - that's what I suspect too, but I do not know where the > change is made! > > > -- SLUG - Sydney Linux User Group Mailing List - http://slug.org.au/ More Info: http://lists.slug.org.au/listinfo/slug

Yes - that's what I suspect too, but I do not know where the change is made! -- Rachel PolanskisOptus/Excite@Home UNIX Administrator 100 Harris Street IT Operations Pyrmont, Sydney NSW [EMAIL PROTECTED]Ph: (+61 2) 900 51144 -- SLUG - Sydney Linux User Group Mailing List - http://slug.org.au/ More Info: http://lists.slug.org.au/listinfo/slug

Check your duplex setting, seeing as you have a dumb hub you might need to force 10mbps/half-duplex Your symptoms sound like your at full duplex.
