After installing Windows 95 on an MP975 there are problems operating the video, audio, or PCMCIA cards.


The following steps need to be followed after completing the default installation of Windows 95.  These steps are required to make the display, sound, and PCMCIA operate properly.  

Prior to performing these steps, you must follow these steps:

  • Remove ALL PCMCIA cards from the system. DO NOT re-install PCMCIA cards until ALL steps have been completed

  • This procedure assumes that your BIOS version is 1.35 or higher.  If you have an older BIOS version, you can get the update from the BIOS Update Article.

  • This procedure assumes that you have the original driver CD ROM which was shipped with the system.  If you do not have the driver CD, you can download the driver pack by Clicking Here.   If you download the driver pack, it will include its own readme.txt with installation instructions.

If you do, the only way to remove it and make PCMCIA function properly is to erase Windows 95 and reload it.
