Using ZENworks DM 7 SP1, NetWare 6.5 SP5.

Have 6 Dell Dimension 9150; one was set up and configured as the master
for a multicast imaging session. 4 were set up as clients for the
multicast imaging session. 3 of the 4 clients received the image from
the master. I am having trouble restoring an image to the 4th Dell. I
have tried autoimaging, manual imaging (both with PXE and with boot CD)
and each time, I get this error message after "loading data into RAM
disk ..." and "Detecting Hardware": "Floating point exception."

[Note: I was able to restore an image to the 6th Dell.]

Any suggestions as to why the 4th Dell gets this error message?
