Gigabit to Gigabit NIC connection (No crossover cable needed)

Aug 24

Posted by Mike in Technical Journal, Technology Recipes | No Comments

With gigabit, you don’t need to worry about crossover, just connect them with one of your cat6 cables.

So actually it turns out (after a little more googling) this is not always true.  It depends on the PCs/Devices being connected together.  Some support auto-negotiation and others don’t.

Here is the pinout for making a gigabit crossover cable (different than 100 Base-T crossover)

2 orange green
3 white/green white/orange

Failed to uninstall the device

“Failed to uninstall the device. The device may be required to boot up the computer”

This happened to me today on an Acronis restored Small Business Server box (to different hardware using universal restore).

The issue is that the HP server that the image came from had HP drivers that ended up blocking the broadcom drivers on the Dell server I was moving to. The way to fix the issue is as follows:

1. Go into a command prompt.

2. type “set devmgr_show_nonpresent_devices=1”

3. Hit return.

4. Type “devmgmt.msc”

5. Hit return.

Once device manager has loaded, go to View, Show Hidden Devices.

You will then see “greyed out” old devices and network cards that you can remove.

Once you reboot all should be well.
