Adapter Memory Location for AVC Slot Installation
Lorenzo Mollicone was trying to bring up a Model 90:

Audible: BEEEEEP, BEEP BEEP, Screen: 20608, then system boots.
iaopt211.exe Options Disk
Slot 1, Enhanced F/W
Slot 3, I-I/A
Slot 2 & 4 Empty.
XGA, 1MB on Board.
24MB RAM, Q Complex

The diagnostic program is not seeing the I-I/A installed. Will try another.
Tried two adapters, neither show in diagnostics, show in SC though

Page 6 of the I-IA Installation Instructions:
If the I-IA is in AVC slot (slot 3 in Model 90), set Adapter Memory Location to C000.

I had to reconfigure the 90 from the ground, and with the C000 window set, that peculiar error went away.

Comments: It appears that the SC did not (or could not) resolve the Adapter Memory Location, hence the Diagnostics shenanigans. A bit odd though, as the later SC.EXE used with the 76/77 systems was the more capable one...

The Image-I Adapter/A does not support the IBM PS/2 Image Adapter/A Printer/Scanner Option (#1632, 07F4402).

WIN.INI Options

[Image Adapter/A]
Resolution=1024 768
You can modify these options by running the IASETUP.EXE program.

   Version is not actually an option but just informs you which version of the Image Adapter/A Windows 3.1 Display Driver that you have.

   X and Y dimensions (in pixels) of the display mode required. See Table 1,2,3,4 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).

   Bits per pixel should be 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).

   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.

At 8 bits per pixel, there are three PaletteManager options,

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".

   This is 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.

   This 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, a display attached to the Image Adapter/A will be used only for running Windows apps. When running full screen VGA apps (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) you should select NO for this option.

   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
   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.

Image Adapter/A (3 MB) Display Modes

8513 8514 8506 8508 6091
640x480 1,2,4,8,16 1,2,4,8,16 1,2,4,8 1,2,4,8,16
1024x768 1,2,4,8,16 1,2,4,8 1,2,4,8
864x1200 1,2,4,8
1280x1024 1,2,4,8
1360x1024 1,2,4,8
1600x1200 1,2,4
8513 column also refers to 8503 and 8512, and
8514 column also refers to 8507, 8515 and 8604

Direct Color Mode (16 bits per pixel)
   Some apps do not cope correctly with 16 bpp, a common symptom is that the application will think that its running on a b/w device and display as gray shades. Many of these apps run correctly if the BitsPerPixel option is set to 15. The driver still runs at 16bpp but it informs apps that there are 32,767 colours available instead of the correct value for direct colour devices which is -1.

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 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 below 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.

Display ID Numbers

Color Mono
640x480 NI 1 2
1024x768 IL 5 6
1024x768 NI 21C 21M
864x1200 IL 10C 10M
1280x1024 NI 11C 11M
1360x1024 IL 21C 21M
1360x1024 NI 8C 8M
1600x1200 IL 8C 8M
Note: IL refers to interlaced displays and NI refers to non-interlaced displays.

Image-I Adapter/A Specs
 The Image-I Adapter/A is a high-resolution adapter, capable of driving displays up to 230 MHz, with a maximum screen addressability of 1600x1280 pels 

9504 Monochrome Monitor (2)
6091-016 Color Display
6091-19i Color Display
1091 Color Display
9517 Color Display.

 The Image-I Adapter/A is available in 3MB only and coexists with VGA on planar, XGA/XGA-2 chipset on planar, or a XGA/XGA-2 Adapter/A card. It can be installed in any 386, -SX, -SLC, 486SX, 486 or higher systems.

VGA data display can only be achieved if the Image-I Adapter/A is installed in the AVE slot.  Image-I Adapter/A may not be installed in slots with the matched memory extension.

The display attached to the Image Adapter can show VGA graphics only if the adapter is installed in the AVE slot. Ideally, the Image Adapter should be installed in the AVE slot unless this slot is already in use (e.g. with an 8514/A Adapter).
