SeeAlso: AX=E802h
--------b-15E801----------------------------INT 15 - Phoenix BIOS v4.0 - GET MEMORY SIZE FOR >64M CONFIGURATIONS
AX = E801h
AX = extended memory between 1M and 16M, in K (max 3C00h = 15MB)
-1-
Saturday, January 08, 2011 11:36 AM
BX = extended memory above 16M, in 64K blocks
CX = configured memory 1M to 16M, in K
DX = configured memory above 16M, in 64K blocks
CF set on error
Notes: supported by the A03 level (6/14/94) and later XPS P90 BIOSes, as well
as the Compaq Contura, 3/8/93 DESKPRO/i, and 7/26/93 LTE Lite 386 ROM
BIOS
supported by AMI BIOSes dated 8/23/94 or later
on some systems, the BIOS returns AX=BX=0000h; in this case, use CX
and DX instead of AX and BX
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.

--------b-15E802----------------------------INT 15 - Compaq Contura - GET ???
AX = E802h
Return: CF clear
AX = 0000h
BX = ???
CX = 0000h
Note: this function is also supported by the LTE Lite 25c, 25E, and 486; not
supported by LTE Lite 20 and 25.
SeeAlso: AX=E801h"Phoenix"
--------b-15E820----------------------------INT 15 - newer BIOSes - GET SYSTEM MEMORY MAP
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)
EAX = 534D4150h ('SMAP')
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)
-2-
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
SeeAlso: AH=C7h,AX=E801h"Phoenix",AX=E881h,MEM xxxxh:xxx0h"ACPI"
Format of Phoenix BIOS system memory map address range descriptor:
Offset Size Description (Table 00580)
00h QWORD base address
08h QWORD length in bytes
10h DWORD type of address range (see #00581)
(Table 00581)
Values for System Memory Map address type:

02h reserved, not available (e.g. system ROM, memory-mapped device)
03h ACPI Reclaim Memory (usable by OS after reading ACPI tables)
04h ACPI NVS Memory (OS is required to save this memory between NVS
sessions)
other not defined yet -- treat as Reserved

--------B-1600------------------------------INT 16 - KEYBOARD - GET KEYSTROKE
AH = 00h
Return: AH = BIOS scan code
AL = ASCII character
Notes: on extended keyboards, this function discards any extended keystrokes,
returning only when a non-extended keystroke is available
the BIOS scan code is usually, but not always, the same as the hardware
scan code processed by INT 09. It is the same for ASCII keystrokes
and most unshifted special keys (F-keys, arrow keys, etc.), but
differs for shifted special keys
-7-
some (older) clone BIOSes do not discard extended keystrokes and manage
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
translate prefix E0h to 00h. This allows old programs to use extended
keystrokes and should not cause compatibility problems
SeeAlso: AH=01h,AH=05h,AH=10h,AH=20h,AX=AF4Dh"K3PLUS",INT 18/AH=00h
SeeAlso: INT 09,INT 15/AH=4Fh
--------B-1601------------------------------INT 16 - KEYBOARD - CHECK FOR KEYSTROKE
AH = 01h
Return: ZF set if no keystroke available
ZF clear if keystroke available
AH = BIOS scan code
Note: if a keystroke is present, it is not removed from the keyboard buffer;
however, any extended keystrokes which are not compatible with 83/84key 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
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
translate prefix E0h to 00h. This allows old programs to use extended
keystrokes and should not cause compatibility problems

AL = subfunction
00h set default delay and rate (PCjr and some PS/2)
01h increase delay before repeat (PCjr)
02h decrease repeat rate by factor of 2 (PCjr)
03h increase delay and decrease repeat rate (PCjr)
04h turn off typematic repeat (PCjr and some PS/2)
05h set repeat rate and delay (AT,PS)
BH = delay value (00h = 250ms to 03h = 1000ms)
BL = repeat rate (00h=30/sec to 0Ch=10/sec [def] to 1Fh=2/sec)
06h get current typematic rate and delay (newer PS/2s)
Return: BL = repeat rate (above)
BH = delay (above)
Return: AH destroyed by many BIOSes
Note: use INT 16/AH=09h to determine whether some of the subfunctions are
supported

AH = 04h
AL = keyclick state
00h keyclick off, leave loudness setting unchanged
-9-
01h keyclick on, leave loudness setting unchanged
else
bit 0: keyclick enabled if set
bits 7-1: new keyclick loudness (non-zero)
Note: Applications which try to set a new loudness, but are unsure of the
results of other INT 16/AH=04h implementations, should set the new
loudness first, and then call this function again with AL=01h or
AL=00h
SeeAlso: AH=03h,AH=04h"KEYBOARD",AX=AF4Dh
--------B-1605------------------------------INT 16 - KEYBOARD - STORE KEYSTROKE IN KEYBOARD BUFFER (AT/PS w enh keybd only)
AH = 05h
CH = BIOS scan code
CL = ASCII character
Return: AL = status
00h if successful
01h if keyboard buffer full
Notes: under DESQview, a number of "keystrokes" invoke specific
DESQview-related actions when they are read from the keyboard
buffer (see #00583)
similarly, some "keystrokes" invoke special functions on the HP 100LX
and HP 200LX (see #00584)

AX = 0600h
AL = next keyboard event in event buffer, FFh if buffer overflowed
CF set on error
AL = 00h buffer empty
BX destroyed
Program: AAKEYS is a TSR by Anthony Appleyard which records keyboard scan
codes in a 256-byte buffer in addition to any normal processing which
takes place
Note: the installation check consists of calling INT 16/AX=06xxh (where 'xx'
is any subfunction other than those listed here) and testing whether
AX=BEEFh on return
SeeAlso: AX=0601h,AX=0602h,AX=0603h,AX=0604h

--------B-1610------------------------------INT 16 - KEYBOARD - GET ENHANCED KEYSTROKE (enhanced kbd support only)
AH = 10h
Return: AH = BIOS scan code
Notes: if no keystroke is available, this function waits until one is placed
in the keyboard buffer
the BIOS scan code is usually, but not always, the same as the hardware
scan code processed by INT 09. It is the same for ASCII keystrokes
and most unshifted special keys (F-keys, arrow keys, etc.), but
differs for shifted special keys.
unlike AH=00h, this function does not discard extended keystrokes
INT 16/AH=09h can be used to determine whether this function is
supported, but only on later model PS/2s

Notes: if a keystroke is available, it is not removed from the keyboard buffer
-13-
unlike AH=01h, this function does not discard extended keystrokes
some versions of the IBM BIOS Technical Reference erroneously report
that CF is returned instead of ZF
SeeAlso: AH=01h,AH=09h,AH=10h,AH=21h,INT 09,INT 15/AH=4Fh
--------B-1612------------------------------INT 16 - KEYBOARD - GET EXTENDED SHIFT STATES (enh kbd support only)
AH = 12h
Return: AL = shift flags 1 (same as returned by AH=02h) (see #00587)
AH = shift flags 2 (see #00588)
Notes: AL bit 3 set only for left Alt key on many machines
AH bits 7 through 4 always clear on a Compaq SLT/286
many BIOSes (including at least some versions of Phoenix and AMI) will
destroy AH on return from functions higher than AH=12h, returning
12h less than was in AH on entry (due to a chain of DEC/JZ
instructions)

Desc: called when there is no bootable disk available to the system

the action is unpredictable on compatibles; this interrupt often
reboots the system, and often has no effect at all
some PC and XT clones had an optional IBM CASSETTE BASIC stored
in the ROM, too.
most BIOSes will display an error message similar to "NO BASIC", and
either reboot or return to the caller.
PS/2 machines usually pop up a graphical box to the effect that
the user should enter a floppy and press F1.
Some clones display the message "No boot device available,
strike F1 to retry, F2 for setup utility"
network cards with their own BIOS can hook this interrupt to allow
a diskless boot off the network (even when a hard disk is present
if none of the partitions is marked as the boot partition)

--------B-19--------------------------------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
-135-
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

--------B-1A00------------------------------INT 1A - TIME - GET SYSTEM TIME

Return: CX:DX = number of clock ticks since midnight
AL = midnight flag, nonzero if midnight passed since time last read
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
-141-
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
-143-
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
EP/SB, leave CF unchanged if successful, so CF should be cleared
