Hi,

I am doing some ethernet tests using the BitsyX board running CE 4.20.17. I need to be able to force the ethernet connection to run at 10BT speed. I came across a post on doing this in the registry for an agx or vgx board. I have not been able to find any registry keys pertaining to this on the BitsyX. Is there a way the connection can be forced to 10BT and how would this be done? Thanks.

Hi Rakesh. I took a look at the reginit.ini file with the 4.20.17 release.

For 10BT half duplex operation, it looks like the new driver would use the following settings:

[HKEY_LOCAL_MACHINE\Comm\LAN91C111\Parms] 
  "DUPLEX"="HALF"             ; HALF or FULL
  "SPEED"="10"                ; 10 or 100
  "AUTO-NEGOTIATION"=dword:0  ; 0 disabled, 1 enabled

Give these a try and see how they work for you.

Edited by akidder 28-Jun-2005: Correct key (LAN90001->LAN91C111) and add comments about values.

It turns out that there is an error in the reginit.ini file I examined. I've corrected the entry above to match what the driver is looking for.

The keys that were used in the VGX and AGX builds to set speed, duplex and auto-negotiation will also work with 4.20.17 (and will override these settings), but we recommend that you use these settings from the new SMSC driver.
