There are now several reports of the BX chipset failing in this manner.
I really don't know what the problem could be -- the PIIX4 works very
well in combination with all other chipsets.

That's something different.. nothing to do with IDE.

Yes and know. All PCI IDE chipsets have a "native" and "legacy" mode,
where "legacy" makes the device appear as ISA after power-on reset.
Not the problem in this case, though.
