ATA buses in the 1712
I was looking at the service manual , and noticed something interesting.The Intel ICH5 south bridge supports TWO IDE buses, each of which can
handle two devices.
But there's only a total of two IDE devices in the box. So I was wondering
what they did with the other possible connections. I assumed they just
used one bus, and left off the connector for the second bus. So the hard
disk would be the master on the (single) bus, and the DVD the slave.
But from the diagram, it looks like they have connectors for both buses!
The hard disk is on one, the DVD on the other.
This implies it should be possible to put a second device on EACH bus.
So you could (theoretically) connect TWO hard disks to the bus for the
hard disk - existing disk is the master, second is the slave.
Likewise on the DVD's bus.
So (theoretically) one could get two notebook-type (slim) drives, cram
them into the single full-sized-disk compartment, and do software
RAID! heh
But such a setup probably wouldn't be worth the trouble - as the
notebook-type disks are slower, so the net result probably wouldn't
be significantly faster than the single fast disk.
But I thought it was interesting. (-;
