Michael Brown 2c84b686bc [build] Use a partition table in generated USB disk images 
The USB disk image constructed by util/genfsimg is currently a raw FAT
filesystem, with no containing partition.  This makes it incompatible
with the use of CONSOLE_INT13, since there is no way to add a
dedicated log partition without a partition table.

Add a partition table when building a non-ISO image, using the mbr.bin
provided by syslinux (since we are already using syslinux to invoke
the ipxe.lkrn within the FAT filesystem).

The BIOS .usb targets are built using a manually constructed partition
table with C/H/S geometry x/64/32.  Match this geometry to minimise
the differences between genfsimg and non-genfsimg USB disk images.

iPXE network bootloader

Build Coverity Release

iPXE is the leading open source network boot firmware. It provides a full PXE implementation enhanced with additional features such as:

  • boot from a web server via HTTP or HTTPS,

  • boot from an iSCSI, FCoE, or AoE SAN,

  • control the boot process with a script,

  • create interactive forms and menus.

You can use iPXE to replace the existing PXE ROM on your network card, or you can chainload into iPXE to obtain the features of iPXE without the hassle of reflashing.

iPXE is free, open-source software licensed under the GNU GPL (with some portions under GPL-compatible licences).

You can download the rolling release binaries (built from the latest commit), or use the most recent stable release.

For full documentation, visit the iPXE website.
