Win95-Setup for S3-928|
Used in the PS/2 9576i / iS and 9577i / iS
The Situation: You have a PS/2 9576i or 9577i and want to run Windows with a resolution over VGA and more colors. But none of the S3-drivers seem to work.|
The Action: Follow these instructions and you will be able to use SVGA-modes with your machine.
The infos on this page refer only to those Models 76 and 77 with the S3-928 VLB-chipset.
These are the machines which don't have an integrated SCSI-adapter on the systemboard and therefore have no IBM SCSI-connector at the left side, looked at from the rear. If the machine has this 60-pin half-pitch Mini-Centronics connector left from the two serial connectors, then it is an older Model 76 / 77 (without -i-), with the XGA-2 Video-System and to which these tips do not apply.
First Step: It is neccessary to start Windows 95 in VGA-mode. If you already tried to set up a different video-driver and failed with this attempt, go back to the Video-Properties (Click with right mouse-button on an empty space at your desktop) and change everything back to standard-VGA, 640 x 480 and 16 colours. Reboot to properly start the VGA-driver.
Second Step: Download the IBM Enhanced Local Bus Dos/Win 3.1 driver disk and extract it to a disk. Yes - the Windows 3.1 driver. That's correct.
Then change to the A: prompt on your PS/2 and run the INST7677 from this disk.
This will install the IBM DMQS (Display Mode Query / Set) on your system, which includes i.e. Informations about the attached monitors and the appropriate resolutions / vertical refresh under the available SVGA-modes. There is also a path set to the DMQS-directory in the AUTOEXEC.
If you are running Windows 3.x you will have to stop at this point and run Windows 3.x Setup from the C:-Dos prompt. Select 'Video' and take 'OEM disk' from the selection. Use the the IBM Dos/Win 3.1 driver disk to install the S3-driver and that will do to be able running all S3-SVGA-modes under 3.x.
Third Step: Download the S3 928 Windows 95 drivers disk from the S3-website and extract it. This may be done either on a separate floppy-disk or in directory on the harddisk.
From the selection list take 'S3 Inc. 928 ISA/VLB'. This is no mistake ! The S3-chipset used on the 76i/77i is a VESA Local Bus system, originally planned for ISA-machines. Nontheless these machines are 'true' MCA-machines - except for the video subsystem.
After installation has finished, you will have to restart the system.
That was it. You are now able to change resolution and colour-depth as required. A good resolution on 14" or 15"-screens is 800 x 600 at 64K-colours. The maximum resolution with the 1MB-VRAM is 1024 x 768 at 256 colours.
Feel free to report experiences.
