Correct. I have solved it by using a Dual Xeon server for DHCP but I think
that the firmware should handle the DHCP allocation delay better. This is
the root of the problem.

Correct. The solution is to hard code the Slimserver IP, but I have had
problems with that in the past and I am reticent to do that.

Doesn't work. I confirmed that yesterday on a unit that was displaying the
dreaded "Waiting for DHCP server" message. I could hold it the power button
all day, the unit had crashed and was not responsive. I don't believe it is
correct for the unit to crash for the lack of an IP.

Correct.
