It just occurred to me to run IVTUTIL and FreeDOS's debug v1.01 as per my Runcom / JSLinux testing...

Like JSLinux using a basic vm86 launch but with a more complete basic PC setup, e.g. basic BDA e.g. COM/LPT port values. Interrupt vector table is setup so that all interrupts (inc. table offsets) point to seg F000h as below:

INT VECTOR POINTS TO --- ------ --------- $00 F000:0000 $01 F000:0004 $02 F000:0008 $03 F000:000C etc $10 F000:0040 .. $20 F000:0080 $21 F000:0084 .. $FE F000:03F8 $FF F000:03FC

Dump of interrupt handling code which looks the same for *all* interrupts:
F000:0000 CD00 INT 00 F000:0002 CF IRET F000:0003 CD01 INT 01 F000:0004 CF IRET F000:0006 CD02 INT 02 F000:0007 CF IRET F000:0008 CD03 INT 03 F000:000A CF IRET etc

[edit]
The latest version of Wine I can use on this PC at the minute is v1.1.31, after dumping the 16bit memory provided by Wine on this PC. I searched the net for the BIOS date used in Wine (13/01/99) which located the main Wine dosmem.c source here: dosmem.c - however it turns out that the 16bit code was "separated" in Wine 1.1.36 - whatever "separated" means - dropped for DOSBox?
[edit2]
Apparently yes, removed as according to WIkipedia:
"...However, Windows 1.x and Windows 2.x support was removed from Wine development version 1.3.12 if DOSBox is installed on the system (see below on MS-DOS)..."

Suggest we create a new thread if anyone wants to discuss Wine+DOS further.
