Have this weird problem on a HP d510c machine. When machine boot up to
pxe, it doesn't find any work to do and shutdown. (other model works,
HP dc7600 etc.)

After some digging around, found ZISWIN contain no data. Register the
wk and still nothing. Try to manually enter the data, and save it. Go
back and check the data is not there again. Try zisedit from bash
prompt, it won't even save.

Completely remove Zen65, reinstall it with Zen65Sp2 and ZEN7 as well
with no luck.

Windows 2000 SP4, Zen65SP1, NWclient 490sp1A.

Anyone has any idea ?
