Title: Setting a Pro100
Post by: Jeff Coleman on December 04, 2001, 04:25:44 AM

I just installed 5.1b on a new test server and went through the drill of using the e100 driver for the Intel onboard NIC.  Works ok, but it is at 10meg half-duplex.  How do I force it to 100meg full-duplex?

dmesg:
Intel(R) PRO/100 Fast Ethernet Adapter - Loadable driver 1.3.20
Copyright (c) 2000 Intel Corporation
e100 - Intel(R) 82559 Fast Ethernet LAN on Motherboard
eth0:  Mem:0xff8ee000  IRQ:9  Speed:10 Mbps  Dx:Half
Hardware receive checksums enabled

Thanks - jeff

Jeff,

I just checked my 5.1b dmesg, on a new server too:

Mine doesn't mention speed or duplex, but I know it's at 100 because I have a 100 Mbps only hub on my test LAN. Does your hub support 100?

I am using a D-Link 10/100 Switch and this is the only port that isn't at full-duplex 100. :<

What's it connected to? If it's the secondary NIC it's intended for use with an external-facing device like a router. The default wake up on an Intel Pro 100 NIC is 10Mbit. It will only switch to 100Mbits if something speaks to it at that rate.

In general, mixed-vendor autonegotiation can be flaky-to-nonexistent.  If the D-Link does use the magic word the Intel expects, it won't throttle up.

Is there a management utility for the D-link?  Or a DOS-mode config for the Intel?  If there is any way to "force" the config to 100 on either device, you'd be in business.  Are there any parameter configurable in the module that loads the Pro100?

getting offtopic but..
my 10mb hub recently died
when i connect two different 100mb cards via a crossover cable they fail to talk to each other, but they both work to a third pc with a 10mb card ?
are the cards damaged or is this not unexpected

Thanks for all the help.  My D-Link switch is an older unit without management capability.  I'm in the process of looking for a DOS config tool to force the NIC to 100/Full.

Cheers - jeff
