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 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 (8ns 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.

Adapter/A with 4216-020 Personal Page Printer
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
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).

Image Adapter/A Options
Image Adapter/A 15-pin Analog Video Connector
An example set of options in the WIN.INI file looks like:
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
Palette Manager enabled
Gray scale palette
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".
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.
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)
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)
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
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:-
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.
Note:- IL refers to interlaced and NI refers to
