+ this interface is used by Windows NT 3.1, OS/2 v2.11/2.20, and is
+ used as a fall-back by newer versions if AX=E820h is not supported
+ this function is not used by MS-DOS 6.0 HIMEM.SYS when an EISA machine
+ (for example with parameter /EISA) (see also MEM F000h:FFD9h), or no
+ Compaq machine was detected, or parameter /NOABOVE16 was given.

+ AX = E820h
+ EAX = 0000E820h
+ EDX = 534D4150h ('SMAP')
+ EBX = continuation value or 00000000h to start at beginning of map
+ ECX = size of buffer for result, in bytes (should be >= 20 bytes)
+ ES:DI -> buffer for result (see #00581)
+Return: CF clear if successful

+ ES:DI buffer filled
+ EBX = next offset from which to copy or 00000000h if all done
+ ECX = actual length returned in bytes
+ CF set on error
+ AH = error code (86h) (see #00496 at INT 15/AH=80h)
+Notes: originally introduced with the Phoenix BIOS v4.0, this function is
+ now supported by most newer BIOSes, since various versions of Windows
+ call it to find out about the system memory
+ a maximum of 20 bytes will be transferred at one time, even if ECX is
+ higher; some BIOSes (e.g. Award Modular BIOS v4.50PG) ignore the
+ value of ECX on entry, and always copy 20 bytes
+ some BIOSes expect the high word of EAX to be clear on entry, i.e.
+ EAX=0000E820h
+ if this function is not supported, an application should fall back
+ to AX=E802h, AX=E801h, and then AH=88h
+ the BIOS is permitted to return a nonzero continuation value in EBX
+ and indicate that the end of the list has already been reached by
+ returning with CF set on the next iteration
+ this function will return base memory and ISA/PCI memory contiguous
+ with base memory as normal memory ranges; it will indicate
+ chipset-defined address holes which are not in use and motherboard
+ memory-mapped devices, and all occurrences of the system BIOS as
+ reserved; standard PC address ranges will not be reported

+Notes: on extended keyboards, this function discards any extended keystrokes,

+ function AH=00h and AH=10h the same
+ the K3PLUS v6.00+ INT 16 BIOS replacement doesn't discard extended
+ keystrokes (same as with functions 10h and 20h), but will always

+Note: if a keystroke is present, it is not removed from the keyboard buffer;
+ however, any extended keystrokes which are not compatible with 83/84-
+ key keyboards are removed by IBM and most fully-compatible BIOSes in
+ the process of checking whether a non-extended keystroke is available
+ some (older) clone BIOSes do not discard extended keystrokes and manage

+INT 19 - SYSTEM - BOOTSTRAP LOADER
+Desc: This interrupt reboots the system without clearing memory or restoring
+ interrupt vectors. Because interrupt vectors are preserved, this
+ interrupt usually causes a system hang if any TSRs have hooked
+ vectors from 00h through 1Ch, particularly INT 08.
+Notes: Usually, the BIOS will try to read sector 1, head 0, track 0 from drive
+ A: to 0000h:7C00h. If this fails, and a hard disk is installed, the
+ BIOS will read sector 1, head 0, track 0 of the first hard disk.
+ This sector should contain a master bootstrap loader and a partition
+ table (see #00650). After loading the master boot sector at
+ 0000h:7C00h, the master bootstrap loader is given control
+ (see #00653). It will scan the partition table for an active
+ partition, and will then load the operating system's bootstrap
+ loader (contained in the first sector of the active partition) and
+ give it control.
+ true IBM PCs and most clones issue an INT 18 if neither floppy nor hard
+ disk have a valid boot sector
+ to accomplish a warm boot equivalent to Ctrl-Alt-Del, store 1234h in
+ 0040h:0072h and jump to FFFFh:0000h. For a cold boot equivalent to
+ a reset, store 0000h at 0040h:0072h before jumping.
+ VDISK.SYS hooks this interrupt to allow applications to find out how
+ much extended memory has been used by VDISKs (see #00649). DOS 3.3+
+ PRINT hooks INT 19 but does not set up a correct VDISK header block
+ at the beginning of its INT 19 handler segment, thus causing some
+ programs to overwrite extended memory which is already in use.
+ the default handler is at F000h:E6F2h for 100% compatible BIOSes
+ MS-DOS 3.2+ hangs on booting (even from floppy) if the hard disk
+ contains extended partitions which point at each other in a loop,
+ since it will never find the end of the linked list of extended
+ partitions
+ under Windows Real and Enhanced modes, calling INT 19 will hang the
+ system in the same was as under bare DOS; under Windows Standard
+ mode, INT 19 will successfully perform a cold reboot as it appears
+ to have been redirected to a MOV AL,0FEh/OUT 64h,AL sequence
+BUG: when loading the remainder of the DOS system files fails, various
+ versions of IBMBIO.COM/IO.SYS incorrectly restore INT 1E before
+ calling INT 19, assuming that the boot sector had stored the
+ contents of INT 1E at DS:SI instead of on the stack as it actually
+ does

+Notes: there are approximately 18.2 clock ticks per second, 1800B0h per 24 hrs
+ (except on Tandy 2000, where the clock runs at 20 ticks per second)
+ IBM and many clone BIOSes set the flag for AL rather than incrementing
+ it, leading to loss of a day if two consecutive midnights pass
+ without a request for the time (e.g. if the system is on but idle)
+ since the midnight flag is cleared, if an application calls this
+ function after midnight before DOS does, DOS will not receive the
+ midnight flag and will fail to advance the date
+ Modern releases of MS-DOS/PC DOS (5.0+???) assume that AL is a day
+ rollover counter rather than a flag, as expected by older releases.
+ DOS 5 - 7.10 (Windows 98 SE) provide an undocumented CONFIG.SYS
+ SWITCHES=/T option to force the old behaviour of the day advancing
+ code, that is using a flag instead of a counter.
+ DR DOS 3.31 - DR-DOS 7.03 handle AL as a flag.

+Notes: DR-DOS 7.02 (after 1998-06-06) and 7.03 hook this function and correct
+ the century to 20xx if the reported year is 1900..1980 to auto-fix
+ ROM-BIOSes which are not Year 2000 compliant. On a running system,
+ it would also correct the rollover bug from 1999/12/31 to 2000/01/01.
+ The latter can be turned off using the new CONFIG.SYS YEAR2000=ON|OFF
+ command, as hooking INT 1Ah can sometimes cause compatibility
+ problems with 3rd party software, e.g. NCR/Symbios/LSI Logic-based
+ SDMS PCI SCSI drivers (including all OEM drivers like from Asus,
+ Noma, etc.), some Flash-BIOS software like Asus PFLASH, Quarterdeck's
+ QEMM Stealth and Quick-Boot features.
+ Using EXCLUDESTEALTHINT=1A, though, will allow QEMM's Stealth features
+ to coexist with the DR-DOS Year 2000 rollover support.
+ Actually, the Y2K-fix is provided since OpenDOS 7.02 BETA 2+
+ (1997-08-13), but although these older releases corrected the
+ ROM-BIOS, they didn't pass all Y2K-test suites and had some obscure
+ and inexplicable PCI problems due to the fact that the original
+ INT 1Ah was called via indirect means. Newer releases, however, use
+ a dynamically fixed-up direct jump to avoid these problems.
+ PC DOS 7 plus Y2K fixes and PC DOS 2000 provide similar, though not
+ identical means, which cannot be switched off.
+ MS-DOS and older issues of PC DOS do not provide any such means, and
+ thus requires extra Y2K-TSRs to be loaded when run on buggy BIOSes.
+BUG: some BIOSes, such as the 1998/07/25 system ROM in the Compaq Deskpro
