I did, but it did not work (cvs from today). The PXE implementation is Intel 
Boot Agent Version 4.0.22, the NIC is an onboard eepro100. Here are the 
messages:

Note that the kernel image _is_ valid. After the sleep, it tries again with 
different results and finally hangs after printing the "API 9d00:0106..." 
line, but I think this is only a side-effect and the real error occurs 
earlier.

Then I tried chaining from Etherboot, and the result is:

Michael, I hope this is of help to you. Please tell if I should do anything 
further to track the problem down.
