IBM XGA Adapter Interface Device Driver for the DOS environment version 2.02
-----------------------------------------------------------------------------
Version 2.02 allows operation with non interlaced monitors.
This release incorporates Display Mode Query and Set (DMQS)
functionality.
-----------------------------------------------------------
In order to use the XGA Adapter Interface with DMQS capability,
the location of the DMQS Monitor Information File must be specified.
This is achieved by a parameter added to the Adapter Interface
device driver line in CONFIG.SYS. This should be inserted
by a text editor, after the Adapter Interface is installed.
An example showing the default DMQS path is shown below.
DEVICE=C:\XGAPCDOS\XGAAIDOS.SYS C:\XGA$DMQS\
------------------------------------------
This file contains information on the device driver required for
the DOS Adapter Interface to run on the IBM XGA video subsystem.

Driver Installation Instructions
--------------------------------
Insert the "XGA Device Drivers Diskette" in drive A, type INSTALL from the
A:> prompt and press Enter. Select option 1, and follow the instructions on
the screen.
During the install process, the CONFIG.SYS is optionally changed (or built) to
load the DOS Adapter Interface Device Driver automatically on system startup.
You may choose not to have the install process do this, but in that case, you
must include the following line in your CONFIG.SYS and restart your system
before you can run the Adapter Interface :
DEVICE=C:\XGAPCDOS\XGAAIDOS.SYS
If you start your system from the D drive, replace C:\ with D:\ in the above
line.
The Adapter Interface software, once installed, consists of a directory
called \XGAPCDOS, containing all the necessary files to load the XGA DOS
Adapter Interface.
On system startup, the XGAAIDOS.SYS Device Driver attempts to load
the XGA DOS Adapter Interface.
If the Adapter Interface cannot be loaded, the Device Driver
issues an error message. Any error message is output immediately after the
copyright statement and is one of the following:-
(-XGA) = No XGA hardware found
(The Hardware is faulty, not present, or display not attached)
(-80386) = Incorrect processor
(The Device Driver requires an 80386 processor or above)

General Information
-------------------
The XGA DOS Adapter Interface consists of a set of entry points callable by an
application, providing access to the adapter's display hardware capability.
There are entry points for:
■ graphics primitives
lines
areas
rectangles
characters
images
■ drawing attributes
color & mix control
∙ color index
∙ color lookup table
∙ logic & arithmetic mix
programmable primitives
∙ line types
∙ area patterns
∙ fonts
∙ markers
■ graphics operations
windowing assist
∙ hardware scissors
∙ restorable state
layering assist
∙ bit plane control
∙ color lookup table
bit block transfer
∙ through or across the planes
∙ bit planes to bit planes
∙ bit planes to/from memory
■ hardware pointer
Refer to the XGA Adapter Interface Technical Reference Manual for
further details. ( Part number 15F2154, form number S15F-2154-00 )
Notes:
------
If you want to run Windows 3.1 you must not install the XGA DOS Adapter
Interface. Remove the following line from your CONFIG.SYS file :-
DEVICE=C:\XGAPCDOS\XGAAIDOS.SYS C:\XGA$DMQS
and restart your system.
Some 8514/A applications explicitly look for the 8514/A version of the Adapter
Interface. This is stored on your disk storage in the file 'HDILOAD.EXE'.
If these applications find this file, they use it and do not function
correctly. If you have previously installed the 8514/A DOS Adapter Interface on
your system, you must remove the 'HDILOAD.EXE' file from your disk storage.
The XGA Adapter Interface is compatible only with Lotus Intel Microsoft expanded
memory emulators (LIMulators) that provide physical address services for DMA
Busmasters.
