c80138ac71 BIOS function 0xE820 for memory map detection
- this function returns a ritcher description of available memory

- is ACPI compliant, ACPI data structures are excluded from free
  memory list

- available memory exported to Minix in a backwards compatible manner

- fallback to the old method if this function not available (old
  hardware)

477b616fe8 Fixed a number of complaints about missing return statements.
Some cases were fixed by declaring the function void, others were fixed
by adding a return <value> statement, thereby avoiding potentially
incorrect behavior (usually in error handling).
Some enum correctness in boot.c.

daca9de450 Fix to make making a bootable cd possible again.
ow that the image has grown beyond the 1.44M that fits on a floppy.
(previously, the floppy emulation mode was used for cd's.)

the boot cd now uses 'no emulation mode,' where an image is provided on
the cd that is loaded and executed directly. this is the boot monitor.

in order to make this work (the entry point is the same as where the
image is loaded, and the boot monitor needs its a.out header too) and
keep compatability with the same code being used for regular booting, i
prepended 16 bytes that jumps over its header so execution can start
there.

to be able to read the CD (mostly in order to read the boot image),
boot has to use the already present 'extended read' call, but address
the CD using 2k sectors.

5927788cdd Added 'bootdelay' feature in boot monitor, it pauses a given number of ms
so the list of programs in the image and their sizes can be seen before the
kernel starts filling the screen.

Added some formatting fixes in installboot and boot monitor itself,
some of the segments were larger than the formatting allowed.
