I doubt it is a lot of use, but I had the same sort of event happen on
a 440FX based system with "Intel 82371SB PCI-to-ISA Bridge (PIIX3) etc."
and I was installing an original Win/95 release onto the box. The secondary
channel vanished (and the CD-ROM attached to it!).  After getting some help
it was explained to me that there is a bug in the original Win/95 that
causes it to disable to secondary channel in the BIOS (because it cannot
recognize the chip-set I think). I had to go to the "erase NVRAM" method
to recover the secondary channel (because the Dell box didn't let you
re-enable it via the BIOS SetUp screen).  Win/95 needed a patch or upgrade
to not cause this lossage on every boot.
