CALL 0060h:0000h - Eagle MS-DOS v1.25 IO.SYS - INITIALIZE
InstallCheck:	MS-DOS v1.25 must be installed

Note:	does not return extended keystrokes
SeeAlso: @0060h:0000h,@0060h:0006h,@0060h:0027h

(Table F0001)
Call Eagle MS-DOS entry point 0003h with:

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

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

InstallCheck:	scan paragraph boundaries E000h to FFFFh for signature string
	  "$PMM" followed by a valid PMM header structure (see #F0092)
Note:	the PMM is only available at system boot -- between the completion
	  of the memory check and the call to INT 19; this includes Option
	  ROM initialization and Plug-and-Play Boot Connection Vectors, but
	  not the Bootstrap Entry Vector (which is called after INT 19)
SeeAlso: INT 2F/AX=4300h,INT 67/AH=40h

			0001h pmmFind (see #F0095)
			0002h pmmDeallocate (see #F0096)
		additional parameters vary by function
Notes:	PMM calls use standard large-model C-language calling conventions
	the caller must provide at least 256 bytes of stack space; BIOSes
	  which support this specification will provide at least 1024 bytes
	  of stack space when calling a ROM initialization vector, Boot
	  Connection Vector, or Bootstrap Entry Vector (thus allowing the
	  Option ROM's code to provide sufficient stack space when calling
	  the PMM)

Call PMM "pmmAllocate" entry point with:
	STACK:	WORD	0000h (function "pmmAllocate")
		DWORD	length of memory block, in paragraphs

		DWORD	handle to assign to memory block, or FFFFFFFh for
			  "anonymous" block
		WORD	option flags
			bit 0: allocate from conventional memory
			bit 1: allocate from extended memory
			bit 2: use alignment based on least-significant set
				bit of requested length
Return: DX:AX = 32-bit physical address of allocated memory block, or
	      size of largest available block in paragraphs, or
	      00000000h if specified handle is already in use, or
	      FFFFFFFFh if allocation failed
Notes:	at least one of bits 0 and 1 must be set in the option flags; both
	  may be set if the location of the memory block is not important
	the specification requires that an Option ROM must use handles
	  compliant with the Plug-and-Play specification (high 16 bits are
	  manufacturer's vendor ID, low 16 bits are vendor-defined); handles
	  whose highest bit is set or highest six bits are all clear are
	  reserved for the BIOS, and the BIOS may flag attempts to use such
	  reserved handles

(Table F0095)
Call PMM "pmmFind" entry point with:
	STACK:	WORD	0001h (function "pmmFind")
		DWORD	handle to be found
Return: DX:AX = 32-bit physical address of allocated memory block, or
	      00000000h if handle is not in use
Desc:	get the address of the memory block associated with the given handle

Call PMM "pmmDeallocate" entry point with:
