PCI_TX1.EXE Installation









Release Reason





As Microsoft Windows 95 was developed before the release of the 430TX 

and 440LX chipsets, this software still has no way of correctly recognizing

those chipsets.  After installing Windows 95 there are two devices not 

being recognized in the <i>device manager</i>.  One is the Universal

Serial Bus, another is the PCI Bridge.  Each of them having an exclamation mark

in front.  For this reason we have released this program.  This new batch 

program does not only solve the USB-problem, but also incorporates the 

earlier version PCI_TX to get rid of the exclamation marks in front of the

PCI bridge.  



Installation Procedure :



1. Start <i>PCI_TX1.EXE</i> from within Win95¡C

2. After restarting you system, find:

	My computer --> Control Panel --> System --> Device Manager -->

	(here click) view devices by connection --> Plug and Play BIOS -->

	PCI ports



Now delete all the PCI-devices in this section



Removal Procedure :



1. Install Microsoft USBsupp.EXE 

2. Delete all <i>Universal serial bus Controller

   in the Control Panel's Device Manager and restart your computer.

   After restarting you system, Win95 will ask for the file 

   uhcd.sys.  You can find this file at:

   C:\windows\system.





Attention :





1. This program does not really provide USB-support.  It only solves the

   problem under Windows 95 of having a yellow question mark.  In case

   you need to use USB-devices, please get Microsoft's USBsupp.EXE program.

2. This program is specifically designed to bridge

   Microsoft Windows 95's shortcoming to accuratly recognize the 430TX & 

   440LX Chipsets. So you should not use it with Win98, as Win98 already 

   incorporates this function, and installing this driver might cause 

   conflicts.
