Is this assumption valid?

Bob,

As I remember Windows 95 does not come with drivers for your chipset the
Intel 82371 AB. If either of the hard drive controllers are running in MS
Dos compatibility mode, you will have to edit the registry to remove the
NOIDE entry at this key :
HKEY_LOCAL_MACHINE\SYSTEM\CURRENTCONTROLSET\SERVICES\VXD\IOS

You can check this by right clicking "My Computer" and selecting
"Properties" from the menu.  Select the "Performance" tab of the "System
Properties"  box, both the "file System" and "Virtual Memory" should say 32
bit not MS Dos Compatibility Mode. You can find the drivers for your
motherboard here (BMIDE_95.exe) if you don't already have them:
http://www.azzaboard.com/download.html

This is MS KB article concerning the Bus master drivers:
http://support.microsoft.com/support/kb/articles/Q151/9/11.asp?LN=EN-US&SD=g
n&FR=0

You will need to install the drivers first, then restart in "Safe Mode" and
uninstall all Hard disk controller drivers.  Restart the system and Win 95
should redetect your hard disk controllers and install the correct drivers.
