PCI to ISA Bridge

Win95 reports that my PCI to ISA Bridge is not working properly.  I have searched, in vain, the internet for a replacement driver to remedy this situation. (Which, by the way, Intel insists is not a problem if I am having no hardware problems...which I am not.)  The best information I have RE: my board and chipset is as follows:
Award Modular BIOS 10/18/96-i430VX-10031996C-00 (v.4.51PG)
     (10/20/1996S)
Intel 82439VX (P54) Chipset
Intel 82371SB PIIX3 ISA Bridge
Board type:  AT
Processor: Pentium 90S
If I could have a point in the right direction it would be most helpful.  I do not intend to upgrade the board or chipset in the near future and would really like to remedy this situation.

Hi,

   I see that your Chipset is an Intel VX and your PIIX3 ISA Bridge is an older one.  Access this site to download the newer PIIX4 driver.  This most likely will solve you problems.

Be careful.
If that is not your motherboard, flashing the wrong BIOS could disable your computer.

There is a PCI Bridge fix from Intel that should fix it for you available here:

http://www.windrivers.com/company/intel/default.htm

Check the readme file there.
Let me know how you make out.
Regards,
Ralph

Hi,

   It is not a Bios upgrade.  It is Intels' newer release of the
PIIX4 driver.  It is most likely the same PIIX4 driver that you would find anywhere else.  Let me repeat, it is NOT a bios upgrade.  It is a separate Intel driver non specific to any motherboard.

dankh,
Sorry, when I went to the link you posted, I saw the flash upgrades.  I just went back and scrolled down the page. I then saw the Win95.ZIP file which is Tekrams 7/15/97 driver.

I don't know what the difference might be, but the one I posted is setupex.exe from intel.com and it's dated 6/06/98.

chuter,
Did you check the readme for the Install wizard?
Let us know how you're doing.
Regards,
Ralph

Hi,

    This is what the read me text says about the PIIX4 downloaded at the site i directed Chuter:

PIIX Bus Master IDE Drivers for Windows 95                    Installation, Usage, and Release Note Information                                                                                             NOTE:                                                            This document refers to desktop systems with                  
the following Intel PCIset devices:                            
82371FB (PIIX1), 82371SB (PIIX3) or 82371AB (PIIX4) in          
conjunction with the following Intel PCIsets:                  
430FX, 430HX, 430TX, 430VX and 440FX                                                            The terms "PIIX", "82371xB" refer to any/all of the          following Intel PCIset devices:  82371FB, 82371SB, 82371AB                                                                            

Also, i went to the site you suggested, Ralph.  I can't seem to find that 6/06/98 date, but the read me file states Updated: Thursday, June 26, 1997

The link provided for the PCI Bridge fix at the  windrivers site downloads the file setupex.exe from intel.com, which is dated 6/06/98. (download it and check properties)

As I said, I don't know if they ARE different, but I always like to use the newest release date that I can find.

Hi,

   I would opt for a newer driver, before i opt for a fix for the older one.  :)
