CALL 0060h:0000h - Eagle MS-DOS v1.25 IO.SYS - INITIALIZE
InstallCheck: MS-DOS v1.25 must be installed
Note: this function should only be called by MSDOS.SYS
SeeAlso: @0060h:0003h,@0060h:0039h
--------D-@00600003--------------------------
CALL 0060h:0003h - Eagle MS-DOS v1.25 IO.SYS - CHECK FOR KEYSTROKE
InstallCheck: MS-DOS v1.25 must be installed
Note: does not return extended keystrokes
SeeAlso: @0060h:0000h,@0060h:0006h,@0060h:0027h
(Table F001)
Call Eagle MS-DOS entry point 0003h with:
nothing
Return: ZF set if no key
ZF clear if keystroke available
AL = keystroke
--------D-@00600006--------------------------
CALL 0060h:0006h - Eagle MS-DOS v1.25 IO.SYS - WAIT FOR KEYSTROKE
InstallCheck: MS-DOS v1.25 must be installed
Notes: if an extended keystroke is available, only the low byte is returned,
and this function must be called again to get the high byte
the BIOS keycode 0000h (Ctrl-Break) is returned as 00h+FFh to avoid
the ambiguity that might be caused by returning the 00h high byte
SeeAlso: @0060h:0000h,@0060h:0003h,@0060h:0027h

CALL xxxxh:xxxxh - BIOS32 Service Directory
InstallCheck: scan paragraph boundaries E000h to FFFFh for signature string
"_32_", followed by a valid header structure (see #F021)
Notes: a 32-bit-code alternate PCI BIOS entry point may be found (if
supported) by requesting the entry point for the API with
identifier "$PCI"
an alternate entry point for INT 1A/AH=B4h may be found (if
supported) by requesting the entry point for the API with identifier
"$ACF"
SeeAlso: INT 1A/AX=B100h
Format of BIOS32 Service Directory header structure:
Offset Size Description (Table F021)
00h 4 BYTEs signature "_32_"
04h DWORD physical address of BSD entry point (see #F022)
08h BYTE header structure version number (currently 00h)
09h BYTE header structure length in paragraphs (currently 01h)
0Ah BYTE checksum (8-bit sum of all bytes in structure, including this
one, should equal zero)
0Bh 5 BYTEs reserved (0)
(Table F022)
Call BIOS32 Service Directory entry point with:
EBX = function
00000000h get service entry point
EAX = service identifier
49435024h ("ICP$") PCI BIOS
46434124h ("FCA$") Plug-and-Play Auto-Configuration
Return: AL = status
00h successful
EBX = base address of handler's code seg
ECX = size of code segment
EDX = offset of handler in code seg
80h unknown service identifier
else
Return: AL = 81h invalid function
Notes: the BSD handler assumes that it is running in a 32-bit code segment
the returned entry points for PCI BIOS and Auto-Config must be called
with the same registers as the real-mode INT 1Ah interface,
including the value B1h or B4h in AH (AMI BIOS v1.00.05.AX1 returns
the same entry point for both interfaces and uses AH to distinguish
which API is desired)
some references indicate that only BL is used for the function number,
though at least one implementation actually checks the entire EBX
register; for maximum compatibility, the upper 24 bits of EBX should
be cleared when calling the entry point

point, but must ensure that any stack arguments are pushed as
16-bit values instead of 32-bit values
