I'm not sure what a screen shows while a machine PXE boots. (Sorry, I'm
blind.) So this may be a dumb suggestion but you can tell what files a
machine is asking the tftp server for during a PXE boot by turning on
verbose mode on the tftp server. With tftpd-hpa, you add -vvvv to the
end of the TFTPD_OPTIONS line at the end of the file
/etc/defaults/tftpd_hpa. Then you can do "tail -f /var/log/syslog" on
the tftp server and watch the client ask for each file in turn durng a
pxe boot. It's quite entertaining, actually. :-)
