Does anyone know, whether there is any documentation of how Windows 95 or 98 assign resources to Plug and Play devices? I'm specifically looking for information what Windows does with what the BIOS has assigned to PCI devices, how it decides what configuration to use for ISA PnP and what it prioritizes.

I'm asking, because I've recently tried to make work together a Creative Audigy card and a Yamaha 719 based ISA board and no matter what I did (I've spent a whole day just switching the configurations for both cards and trying some other solutions), Windows would fail on the next restart after installing the Audigy drivers (it would hang during boot with a black screen and a blinking cursor). The solution was to initialize the ISA card with UNISOUND in AUTOEXEC.BAT, after what Windows would happily configure the card with what UNISOUND assigned and chose non-conflicting settings for the Audigy (VXD, without the SB16 emulation driver). I'm curious how, why Windows failed to do it on its own.
