Files:
ixpe.iso	- bootable CD/DVD iso image
ipxe.usb	- bootable USB image
ipxe.lkrn	- load this kernel using GRUB/LILO/...
*.[k]pxe	- load these using DHCP

=======================================================================

To create a bootable floppy, type
    cat ipxe.dsk > /dev/fd0
where /dev/fd0 is your floppy drive.  This will erase any
data already on the disk.

To create a bootable USB key, type
    cat ipxe.usb > /dev/sdX
where /dev/sdX is your USB key, and is *not* a real hard
disk on your system.  This will erase any data already on
the USB key.

To create a bootable CD-ROM, burn the ISO image 
ipxe.iso to a blank CD-ROM.
