Dirk,
when I reboot a Motorola MVME5110, it takes ages (30 sec to be exact)
until the vxWorks boot procedure starts. It takes another 30 seconds
starting the loaded vxWorks kernel.
Does anyone know what the board is doing in all that time?
The MVME2306 have never waited for so long. Can I reduce that time?

I see exactly the same 30 second delays on MVME2700 when they are connected to certain models of Ethernet switches. I believe it is a problem with the 10/100 or full/half duplex negotiation. I have always been able to eliminate the problem by putting an Ethernet hub between those switches and the MVME2700. I believe that Andrew Johnson made changes to the bootrom code and BSP to try to fix the problem, but they did not help.

The delay is *before* anything happens on the network:
-> reboot
[30 seconds delay]
Press any key to stop auto-boot...
 0
auto-booting...
[all the boot parameters printed here]
Attached TCP/IP interface to fei0. [no delay here!]
Attaching network interface lo0... done.
Loading... 1461088
Starting at 0x100000...
[30 seconds delay]
Attached TCP/IP interface to fei unit 0 [no delay here!]
Attaching network interface lo0... done.
....
The delay also happens when I boot from TFFS (flash file system) with no
network connected.
