Thanks for the swift reply. I already found the problem, namely, my tftp server had no support for "tsize". After switching to hpa-tftpd everything worked fine.

However, a lot of confusion stemmed from the fact that manual loading from "boot:" prompt worked all along. If it's not feasible to remove "tsize" feature dependence may it be possible to make "boot:" prompt loading routine to behave in exactly the same way as automatically invoked one?
