Notes: INT 6F corresponds to IRQ23 on the original HP Vectra AT, which is
unavailable because of its use as a BIOS extension software interrupt
the INT 6F handler consists of an instruction to load DS with the
driver's data segment followed by an indexed far jump using BP to
select the destination vector; since the interrupt handler is
located immediately following the dispatch table, the HP_VECTOR_TABLE
may be found by looking at offset 0000h in the INT 6F segment, and
its size is equal to the offset of the interrupt handler
each entry in the HP_VECTOR table consists of a DWORD for the driver's
entry point address and a WORD for the driver's data segment
this function is not user-callable, as it is a response to a physical
event, and assumes that the caller has already handled the physical
interrupt and updated the Describe Record (see #03749) to reflect
the event

Return: AX = error code (see #03787)
Note: The HugeRealMode Server requires an XMS-driver like HIMEM.SYS loaded
before HUGEREAL (for XMS-memory allocation and A20 control). It
utilizes some undocumented 386+ features to enable 4G code and data
segments (flat memory model) in the CPUs real-mode. It is not
compatible with V86-mode (as with most EMM386). For maximum speed
and compatibility with DOS it uses a two stage interrupt model
(see #03791)

Call HugeRealMode Server "Enable Two-Stage Interrupt Model" function with:
AL = 03h
Return: AX = error code (see #03787)
Notes: If the two stage interrupt model is disabled, the IP must stay below
1MB, because the high word of EIP is not saved correctly by the
standard interrupt management in real mode. Routines in extended
memory may only be called with interrupts disabled (only usable for
very short routines).
If the two stage interupt model is enabled, these conventions are not
required. The outer (transparent) ISRs save the higher word of EIP
in the high word of CR3 (possible modification: in memory, if this
is not safe) and then invoke the standard ISRs.
Because of this handling, one should use pseudo segmented code even in
extended memory (64K blocks located on 64K boundaries) to avoid the
misalignment of the saved EIP (in CR3). Another way is to track and
realign CR3 each time when jumping over a 64K boundary in extended
memory

INT 7A - Novell NetWare - LOW-LEVEL API - Notes
Note: this interrupt is used for IPX/SPX access in NetWare versions through
2.0a; in later versions, you should use INT 2F/AX=7A00h to get an
entry point even though INT 7A still exists. For both INT 7A and
the FAR entry point, BX contains the function number; IPX is
sometimes called internally with BX bit 15 set, which causes the
handler to bypass some initial checks and an optional call to the
IPX Windows support handler set with INT 2F/AX=7AFFh/BX=0000h
(see #02926)

address. If the target is in the same network, the local target is
just the node address of target; otherwise, the local target is the

this interrupt is used for IPX/SPX access in NetWare versions through

entry point even though INT 7A still exists. For both INT 7A and
the FAR entry point, BX contains the function number

ES:BX -> Mbuf (see #03847)
Return: nothing
Notes: The DLI will send LENGTH bytes found in the Mbuf's DATA area starting
at OFFSET. A complete and valid frame must be stored there. The DLI
will only copy the current node address (see AX=0003h) to the
source node field of the frame's MAC header.
On Ethernet, the DLI will always send a minimum of 60 bytes, regardless
of the value found in the LENGTH field.
This function returns immediately; the DLI will call the protocol's
Transmit Upcall (see #03848) when the frame has been sent.
The Mbuf's IN USE field will be non-zero until the DLI calls the
Transmit Upcall.

Values SK-UPPS Transmit Upcall is called with:

header have been bit-swapped to physical address format.

INT 7C - SK-UPPS Data Link Interface API - REGISTER PROTOCOL
AX = 0007h
ES:BX -> Protocol Control Block (see #03849)
Return: AX = completion code (see #03846)
Program: SK-UPPS is the Schneider & Koch Universal Portable Protocol Stack,
which provides an API on top of its Data Link Interface, allowing the
use of any of several network transport layers
SeeAlso: AX=0008h,AX=000Bh
Format of SK-UPPS Protocol Control Block (PCB):
Offset Size Description (Table 03849)
00h WORD (big-endian) protocol type
02h WORD protocol mode (see #03850)
04h DWORD -> Receive Upcall routine (see #03851)
08h DWORD -> Transmit Upcall routine
0Ch DWORD -> Event Upcall routine (see #03853)
10h DWORD -> ASCIZ protocol name (zero if none)
14h WORD protocol ID will be returned here (always non-zero)
Bitfields for SK-UPPS protocol mode:
Bit(s) Description (Table 03850)
0 promiscuous mode; protocol receives all frames regardless of their
destination (PROTOCOL TYPE must be FFFFh)
1 if set, protocol's Event Upcall will be called on entry and exit of the
DLI's Interrupt Service Routine (see #03854)
2 DLI 2.2+ hook mode; protocol receives all directed frames destined for
this station (PROTOCOL TYPE must be FFFFh)
3 DLI 2.3+ receive error frames (only valid in promiscuous mode (0))
4-5 DLI 2.5+ frame type:
00 Ethernet II; specify type code in PROTOCOL TYPE field (high-low)
01 IEEE 802.2; specify Service Access Point (SAP) in MSB
(offset 0) of PROCOTOL TYPE field; LSB must be zero
10 IEEE 802.2 with SNAP header; specify type code in PROTOCOL TYPE
field (high-low)
11 reserved (currently unused)
6 DLI 2.5+ if set, protocol's Event Upcall will be called with event code
EV_BUFFER_WANTED, when DLI runs out of Mbufs
7 DLI 2.7+ chain mode; if set, client allows the specified frame type to
be shared with other clients
8 DLI 2.8+ receive non-LLC frames rather than LLC frames
9 DLI 2.8+ receive all multicast frames (see also AX=0009h)
10-15 reserved (currently unused; must be zero)
Notes: If PROTOCOL TYPE is FFFFh and neither the "promiscuous" nor the "hook"
mode is set, the protocol receives all frames that did not match
any registered frame type (demultiplexor mode).
Protocols using "promiscuous", "hook" or "chain" mode should always
return from the Receive Upcall with the received Mbuf in ES:BX and
the Carry Flag set. The DLI will then pass the Mbuf to the FEED BACK
BUFFER function (see AX=000Fh).
Some DLIs do not support all or even any of the "promiscuous",
"receive non-LLC" and "receive all multicasts" mode bits.
SeeAlso: #03849
(Table 03851)
Values SK-UPPS Receive Upcall is called with:
ES:BX -> Mbuf
AX = receive status (see #03852) (also stored in Mbuf's RECEIVE STATUS field)
interrupts disabled
Return: nothing
SeeAlso: #03853
Bitfields for SK-UPPS receive status:
Bit(s) Description (Table 03852)
0-2 reserved (0), currently unused
3 frame check sequence (FCS) error
4 overflow (frame too long)
5 framing error
6 reserved (0), currently unused
7 non-LLC frame (see #03850 [bit 8])
8-15 reserved (0), currently unused
Notes: The protocol's Receive Upcall routine will be called whenever a frame
matching the specified frame type is received. A received frame is
passed to the protocol in the Mbuf's DATA area at OFFSET and its size
is LENGTH bytes.
The receive status passed to the Receive Upcall in register AL is
always zero, except for protocols using "non-LLC" mode (8 of PCB's
protocol mode field) or "promiscuous" mode together with "receive
error frames" (0 & 3).
Upcalls are FAR routines and must return with a RET FAR. If the Carry
Flag is set on return from a Receive or Transmit Upcall, then ES:BX
must point to an Mbuf, which the DLI will then pass to the RELEASE
BUFFER function (see AX=0005h). See also notes for PROTOCOL MODE.
(Table 03853)
Values SK-UPPS Event Upcall is called with:
AX = event code (see #03854)
