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)

86a23c1fbd Remove U16_t and most other similar types. Rewrite functions to ansi-style
declaration if necessary.

c114df82ec Rename all uses of U8_t to u8_t and remove U8_t, remove unused I8_t,
Remove all uses of U16_t and U32_t in pci-related code.
If necessary to avoid problems, change functions to ansi-style declaration.

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.

32dfc999ce - no more separate cd booting stuff (handled in FS now)
- scan_keyboard() asm function that reads char from keyboard
   controller in case one is in there to avoid stuckness when
   returning from minix
