Problem with netboot Mac OS X 10.4 Tiger

[pierrot]

I have a big problem today ! Like everybody I know :)
I have a XServe Power PC G5, I want to re-install it but I don't have video output, no external cdrom drive... So I decide to use NETBOOT :
I have this message in server admin => netboot log (/var/log/system.log) :

/private/tftpboot/mach* missing

So I have tried to put all image files in the directory /private/tftpboot/ but it still doesn't work => Same message.

Someone ?
