Differences Between 07Fnnnn and
06G822n
The '90 07F2511 is littered with decoupling caps... It has
a 4.0 MHz crystal above U33, and a 4.0 MHz osc to the
lower left of J1. U33 is 9019 and U31 is 9034. BIOS is
17/10/90. All logic is through-hole but all memory is
through-hole DIPs or socketed DIPs/ZIPs.
The '92 06G8224 [35G4719] only has a 4.00000 MHz osc above
U33 and NO XTAL. The glut of decoupling caps are gone,
much smaller SMD logic chips have replaced more than a
third of the logic, but all memory is still through-hole
DIPs or socketed DIPs/ZIPs. U33 is 9226 and U31 is 9223.
BIOS is 15/06/92.
The 07Fnnnn versions will positively blow chunks with an M
complex. The 06G8224 will work with the M complex...
Huh, I see a 35G4715 / 06G8224, with a DSC of 9106, yet I
see other 06G822x with chip dates of '92... Can't prove
it, but this makes sense if the 8221, 8222, and 8223 are
the same board but with / without options disk. I wonder
if 8224 has the 1.04 options disk...
Installation of IBM PS/2 IA/A in 32-bit system slots is
restricted to those without matched memory extension.
DSC Date Code
While comparing the 07 and 06 variants of the Image /A, I
was stumped on deciphering the date code of the DSC, U43.

Look at the eleven digit code on the third line. The first digit is the year
digit starting in 1990. The second and third digits are the week.
So, "020" Means 1990, week 20.

Image /A Block Diagram

The Display Support Chip A small gate-array VLSI chip providing
synchronization and timing pulse generation for the display and Image Adapter
card.
Image Adapter/A DCP and DSC Functional Islands

Image /A Display Processor Block

Image/A Serializer / Palette /
DAC Block [SPD]

The Serializer/Palette/DAC circuit types integrated on a
single chip:
1. High speed static RAM (8 ns access)
2. Logic (6000 cells)
3. Digital-to-Analogue convertors, custom designed
4. Phase-Locked-Loop and Voltage-Controlled-Oscillators
The SPD chip provides all the function of the INMOS GI71
component used on PS/2 planars and in the IBM 8514/A
display adapter.
However, the SPD has improved flexibility and function
over the IBM VGA and 8514A:
INMOS G171 compatible palette & DAC
Colour comparators for diagnostic verification of DAC
outputs
32 bit to 8 bit serializer
Cost-reduced DAC current and comparator voltage reference
sources
Clocks and dividers for PS/2 monitors of 25.175, 28.321,
& 44.90 MHz.
Additional function and flexibility is provided:
256 by 24 palette with 8 bit DACs
Support for a video data word width of 8, 16 and 32 bits
formatted as 1 , 2, 4, 8 and 16 bpp.
Generation of video logic and shift clocks for the CRTC
and video RAMS
Differential current outputs.
From what little I see, 16bpp is "palette bypass" [Direct
Color] like the original XGA.

Using Image Adapter/A with 4216-020 Personal Page Printer
>FWIW, I was told once by a Lexmark rep that you
could also talk to this printer through a port on
the Image Adapter/A card. I never had an IA/A
myself, so I'm not sure if this meant all IA/A's or
a certain version or possibly a special
daughtercard.
1. This is only applicable for the "Image Adapter /A" -
not the Image-I-Adapter.
2. You need the "Printer / Scanner Feature Card" FRU
07F4403 and the "Printer / Scanner Y-Cable" FRU
07F4417. Probably the "Memory Module DRAM" (Kit)
07F44407.
The Y-cable connects to the IBM 3117 Scanner on the one
side and to the 4216-020 "Raw Engine" on the other
port. However: the driver support was rather poor
(Win 3.0 / 3.1 and OS/2 up to 2.0 only IIRC). Have
seen this combo at a customer once (back in 1991 or
so) but never worked with it nor serviced it.

The Image Adapter/A is capable
of driving displays up to 128 MHz, with a maximum
resolution of 1600x1200 pels. The Driver output
impedance for video signals is 75 ohms. The sync lines
of the adapter are TTL levels driven by 4ma drivers, so
termination should be at 750 ohms (minimum)
It contains a 32
bit 8.5 MIP display processor, a 128 MHz serializer,
video palette, digital to analog converters and a CRT
controller.
Memory consists
of 1MB VRAM (U10-17), optional 1MB of VRAM
(U18-25), 512KB of instruction RAM (U26-29) and
1MB DRAM Memory Expansion (U2-9).

BitsPerPixel=8
PaletteManager=Yes
MemoryUsage=Maximum
DualScreen=No
StretchBlt=Yes
VirtualScreen=No
Version Version of
Image Adapter/A Win3.1 Display Driver .
Resolution X and Y
dimensions (in pixels) of the display mode required. See
HERE
for a list of valid modes. If an invalid mode is
specified, the driver reverts to its default (the
highest resolution available on the display
attached).
BitsPerPixel
Specified as 1, 2, 4, 8 or 16. Note that some of the
higher bits per pixel are invalid in some of the Image
Adapter/A memory configurations. If an invalid bits per
pixel is specified, the driver reverts to its default
(the highest bits per pixel available (up to 8) at the
selected resolution).
PaletteManager At
1, 2 and 4 bits per pixel, the palette is fixed to 2, 4,
and 16 colors respectively. The Palette Manager options
do not apply and are ignored. Dithering is enabled to
approximate colors that are not in the palette. At
16 bits per pixel, the adapter is in direct color mode
and there is no palette, the Palette Manager options do
not apply and are ignored. Dithering is disabled.
Three PaletteManager options,
at 8 bits per pixel
YES
Palette Manager enabled
At 8 bits per pixel (256 color
mode) only 20 system colors are assigned (10 at the
bottom and 10 at the top). The remaining 236 colors are
available for the Palette Manager to assign to
applications that request them. For applications that do
not use the Palette Manager, dithering is enabled to
approximate colors that are not in the system palette.
This is the default setting at 8 bits per pixel.
NO
Palette
Manager disabled
At 8 bits per pixel the palette
is fixed to a particular set of colors. Dithering is
disabled, the driver selects the nearest color available
from the fixed palette.
GRAY
Gray scale palette
At 8 bits per pixel there are
256 shades of gray (even on a color display). In all
other aspects it is like the fixed palette. This option
may be useful for certain applications. This is NOT
usually the best palette to select for monochrome
displays, unless the application is specifically
designed for gray level displays.
If you need to switch this option on or off see
"Switching the Palette Manager On and Off".
MemoryUsage
Reserved for special applications designed to run only
on the Image Adapter/A. Unless you are using one of
these special applications this option should always be
set to Maximum.
DualScreen Only
applies when you have two displays attached to your
system. For example, a VGA display attached to the
standard VGA port of the system unit and a high
resolution display attached to the Image
Adapter/A.
NO
The display attached to the Image Adapter/A will always
be used as the main display for running Windows
applications and full screen VGA applications. When
running full screen VGA applications both displays will
be showing the same results. This is the default
setting.
YES
During a Windows session the display attached to the
Image Adapter/A will be used only for running Windows
applications. When running full screen VGA applications
(from within the Windows environment) only the VGA
display will display the VGA application. Windows
applications running in the background on the Windows
display will continue to be updated.
If you have only one display (attached to the Image
Adapter/A), select NO for this option.
StretchBlt Whether
the driver registers its capability to scale
images.
YES
The display driver will register the StretchBlt
capability and image scaling will be preformed by the
adapter. This results in a considerable performance
improvement. This is the default.
NO
The display driver doesn't register the StretchBlt
capability and the Windows graphics engine simulates the
image scaling in software.
VirtualScreen X and
Y dimensions(in pixels) of the virtual display mode
required. The x possible value is 1024,2048, 4096 and y
possible value is 1024,2048,3072,4096. See Table 5,6,7
for a list of valid modes. Virtual screen is not
supported with only 1MB card. If invalid value is
specified, virtual screen is disabled. If you want to
disable virtual screen, specify
"VirtualScreen=No".
Display Modes
The following tables show the display resolutions and
bits per pixel available for the various display and
memory configurations. The numbers represent the bits
per pixel. A blank box means the resolution is not
supported. There is more information, in the READ.ME of
Display support diskette. Refer it for the detail.

How to Install Display Data Files to
Your System
Image Adapter/A version 2.00 or later drivers
automatically detect the attached monitor and find correct
Display Data File. You can also specify the name of
Display Display Data File to be used and its
directory.
Each driver expects the default directory path to find
Display Data File if no special path is specified. The
default directories are as follows.
DOS AI: C:\IMGAIDOS
Windows: C:\IBMIAA
OS/2: C:\OS2\IBMIAA (C: is the boot drive here)
AIX: /usr/lpp/ibm-iaa/lpp.ddf
If you wish to specify Display Data File name, please
add the option to your system CONFIG.SYS driver
statement like the following example. (The case of
Windows driver)
DEVICE=C:\IBMIAA\IADOSRFS.SYS /DisplayID=49C
Where, 49 is decimal value of hex 31 (DISPFILE.031),
and 'C' indicates this is a color monitor. If you change
'C' to 'M', driver assumes the attached monitor is a
monochrome monitor which has the same timing.
If you wish to change Display Data File directory other
than default, please add the option like the following
example. (The case of OS/2 driver)
DEVICE=C:\OS2\IBMIAA\IAOS2RFS.SYS /DisplayPath=E:\DDFPATH
You cannot change default Display Data File path in AIX
driver by this option. Please refer to readme file in
each driver diskette for further information about each
driver installation.
Using Non-Standard Displays
The Image Adapter/A can connect to any display that is
compatible with the IBM Displays, 8503, 8506, 8507, 8508,
8512, 8513, 8514, 8515 and 6091 19". To enable other
displays to operate correctly you may need to override the
display ID that is returned by the display.
The display ID override is a command line option that
should be placed after the DEVICE=IADOSRFS.SYS line in
your CONFIG.SYS. For example to override the display ID
to 8 for a color display the line would look like:
DEVICE = C:\IBMIAA\IADOSRFS.SYS /DisplayID=8C
Table 9 lists the different ID's that should be used
for the various possible modes. Note that you still need
to specify the correct resolution in the WIN.INI
file.

Painful Probulation (from WBST)
I've been delving into the registers used by the DOS
Adapter Interface device driver for these variants (IDs
8DF0-8DF5, possibly including 8DF6-8DFF from the code).
Initial comments:
Driver chains Int 7Fh
Support for up to 4 adapters at the same time
Driver uses Int 15h AH=C4h, AL=00h-02h calls to query and enable adapters
Multi-Card Adapter

Note: WBST
cautions: Extended Memory window can only be enabled if,
at most <=14MB is installed in the system. A slightly
important caveat. This becomes a concern in later
systems.
Interrupt Level
The Interrupt level is fixed at 2
