Yes, just two drives.  You've got a hybrid system with the typical
limitations of hybrid systems: the new technology is supported, but you
will find ourself wanting an upgrade when the new technology becomes the
standard one.

Seven years ago I bought my first system with PCI slots.  There were three
common standards of the time for improving ISA: EISA, VLB, and PCI.  VLB's
time had since passed and, and it was common still to see boards with two
ISA, two EISA or VLB, and two PCI.  The PCI on these boards was so-so, and
there were only two.  PCI-only boards were unheard of (and technically
speaking still are for ia32 machines which still provide an ISA bridge for
AT keyboards, PS/2 mice, and floppy drives..)  But still, ISA implemented
as a bridge to PCI allowed PCI to be the dominant system architecture and
its performance has been good enough until now.

At that time, I had the foresight to buy a board with only two ISA slots
and four PCI.  They were rare in those days.  Very rare.  Two years
later it was still common to see three ISA slots, though it was no longer
uncommon to have only two.  It didn't matter, though, because the PCI was
not constrained by ISA.


SATA on your board is constrained both by IDE and by PCI.  There;s no help
for it I'm afraid.  Look for PCI-X systems with SATA in the near future to
provide more ports and more throughput than either IDE or PCI.
