hard disk I/O is in ATA bus, and PCI has it own bus on the chipset (see
page 69):
http://downloadmirror.intel.com/19123/eng/d525mw_d525mwv_techprodspec.pdf
and page 14:
http://download.intel.com/support/motherboards/desktop/d865gsa/sb/d5600601us.pdf
But these are terminologies. At the source code level, (and tools as
well), PCI and ATA are not differentiated much:
in drivers/ata/ata_piix.c, and in drivers/pci/quirks.c both directory u can
see 82801 symbols exists.
For your problem i think it is a BOCHS problem...mixing with recent linux
kernel (older kernel should be fine)...eg,
http://forums.gentoo.org/viewtopic-t-915210-view-previous.html?sid=a003ebbc022d7f23399fc7f1c5dad424
(notice the 3.2 kernel) which is resolved via setting the PCI configuration
in BOCHS as well. take a look.
