I came onto a Serial ATA hardrive by accident. PC1066 RDRAM has been
out of style for a while now, so I'm looking for any motherboards that
used PC1066 and had serial ATA integrated? The newer the boards the
better. I don't have the funds to buy a new ram/motherboard and
possibly processor combination at the moment or all at once for that
matter... and a serial ATA card can cost as much as some
motherboards... mines been wonky, so I figured I'd consider replacing
it. I'm aware of one low performance SiS R658 chipset that was out for
a really short period of time... but they apparently weren't very good
and were produced in very limited numbers... so don't point me there
if possible. ;) Thanks.

I have searched all the major brands but cannot find everything that
you are looking for. The closest I could come was the Asus P4T533-C
(Intel 850E) Series motherboard that will support your RAM type and
speed, requires a Pentium 4 processor, but DOES NOT HAVE SATA. You can
get a SATA to IDE conversion kit for your hard drive, but there seems
to be no all-in-one motherboard that you need.

Thanks a alot for looking. I was kinda worried that might be the
answer. hehe... I REALLY appreciate the looking.
