Forcing Half-Duplex

Hey:

I remember years back I had an OS 9 machine that had trouble connecting to a 10/100 switch, and there was a bit of software that I got from Apple that allowed you to force the NIC to go either half or full duplex. Does anybody remember what that is called or from where it can be downloaded? I've got a friend who is dealing with a similar problem, and I'm hoping this might be the magic bullet, but I sure can't remember what it was called!

Thanks!

humm that sounds intresting.

humm that sounds intresting. i would love to know what this software is called also. to see if it would help on some areas in networking with my router. right now my router is set to use 10 base T half duplex and i would love to get the system to at least to full

Here's A Start...

It's called [url=http://docs.info.apple.com/article.html?artnum=60436
]Apple Ethernet Speed and Duplex Tool[/url]. It's advertised to only work on specific machines, but I remember using it (or something similar) on a G4. I'm not sure if this is the bit that I was looking for or not.

Is your router at half-duplex because you set it that way or is that its default? If your router's ports aren't configurable, this may not help in your situation.

ok then so this would not wor

ok then so this would not work on a Beige G3 since the hardware only supports 10 baset half duplex. basicly it disables the auto negotiation of the Nic to determin the speed it uses and sets it (if the hardware is capable ) to the installed extensions speed.

It probably won't work,

... if your hardware only supports 10baseT half-duplex. Sounds like your trouble is more with the switch than with your NIC.

10/100 PCI cards are pretty reasonable these days, and might be a decent solution for you. I might even have one in a box at home I could send to you. Interested?

no any Beige G3's nic hardwar

Any Beige G3's onboard nic hardware only supports 10baset half duplex (its the way they was designed). they dont support 10baseT full duplex. they might work with a router running 10baseT full but the Beige G3 will only use 10baseT half.
