Now we will take GPXE to boot an iso disc image through http protocol.
This time I tried with an Hiren BootCD iso image – a very famous and popular All-in-One BootCD. It takes about less than 30 seconds to load and boot the image using 100Mbps LAN network. If move to Gigabit network, the time will be much better.
To boot the iso file, grub4dos does use (0xff) mapping instead of (hd0). Detail entry menu which used this time :
Server# cat /var/ftpd/pxelinux.cfg/default
APPEND --config-file="map (rd)+1 (0xff); map --hook; chainloader (0xff)"
And it works perfectly.

- You can gzip the iso image to smaller size to get much better speed.
