Image Adapter/A

Not done with this yet. Some components aren't identified, as I think they are support chips. I only have so much time. I do need to add another bank of VRAM plus U2-U9.

Image Adapter/A
imageopt.exe   PS/2 Image Adapter/A options diskette, version 1.04
      The Image Adapter/A is a high-resolution adapter, capable of driving displays up to 128 MHz, with a maximum screen addressability of 1600x1200 pels. The Driver output impedance for video signals is 75 ohms. The sync. lines of the adapter are TTL levels driven by 4  ma drivers, therefore the termination should at the very least be at 750 ohms 
       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 on the adapter comprises 1Mb of video RAM and 512Kb of instruction RAM.  A 1Mb DRAM Memory Expansion Kit is available for applications requiring additional data memory or improved performance. 
       A Printer/Scanner Option (#1632) is available with the adapter allowing the direct attachment of the following devices: 
o   IBM 3812 Printer Model 002 with Image Feature (#4050) or IBM 4216 Personal Pageprinter Model 020 
o   IBM 3117 Scanner with extension unit (PN 6456808) or IBM 3118 Scanner or Bell & Howell 2115I (1) Scanner or equivalent 
       IBM PS/2 Image Adapter/A enables both a scanner and a printer to be attached at one time via this optional printer/scanner daughter card. Use of the Printer/Scanner Option does not require an extra system unit slot. 

Image Adapter/A 1MB is available with one megabyte of Video Memory (VRAM). It can be upgraded to three megabyte of VRAM and the Image Adapter/A Memory Expansion Kit 
Image Adapter/A 3MB has two megabytes of VRAM and the Image Adapter/A Memory Expansion Kit already installed 
Image Adapter/A 3MB 6091 is the same as the Image Adapter/A 3MB, but also has a cable for attaching an IBM 6019-019 Color Display 

      The three versions of the Image Adapter/A support IBM analog displays equipped with a 15-pin direct-drive analog interface 

      It can be installed in any IBM PS/2 MCA system unit, except portable models 

 6019-019 Display Cable
   This cable is required if the Image Adapter/A is supporting an IBM Color Display 6019-019. The cable is supplied with  the Image Adapter/A 3MB 6019. The cable must be ordered separately for all others 

Image Adapter/A Options 
 You can attach optional features only to the Image Adapter/A 
   1. Printer/Scanner Option 
   2. Memory Expansion Kit
   3. PS/2 Video Memory Expansion Option 
      . 
  For a single display configuration, you must always attach the display to the display connector on the Image Adapter/A and not to the system- unit display connector

An example set of options in the WIN.INI file looks like:

[Image Adapter/A]
Version=2.2
Resolution=1024 768
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 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).

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 colours 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".

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) you should 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 infomation, in the READ.ME of Diplay support diskette. Refer it for the detail.
 

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.
