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
Page 6 of the I-IA Installation
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).
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
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
At 8 bits per pixel, there are three PaletteManager
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.
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
GRAY Gray scale
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
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
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
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

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:
DEVICE = C:\IBMIAA\IADOSRFS.SYS /DisplayID=8C
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
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
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
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).
