I have no problem with SATA drives. I dont think they would work for
Win98 though. One thing about them, I dont understand why the data cable
Some BIOS/MOBOs can make them "look like" an [E]IDE drive. I don't know
if that would make W98 be able to use them.
Intel provided that mode specifically for legacy OSes. Because
it shows up in I/O Space for the registers, and it uses INT14
and INT15 for the interrupt coming from those logic blocks. It
looks exactly like a crusty old IDE Southbridge.
That was Compatible IDE mode.
I managed to install Win98SE on an Asrock VIA board with a Core2
processor, and it screams. Even though it only can use one core
of the processor. So yes, you can run Win98 on at least some
I think the Compatible mode disappeared at some point.
The Native IDE mode, the registers are in PCI space, and the
interrupts fall where-ever the equivalent of INTA would go.
WinXP has a driver for that, in-box I believe. WinXP doesn't
have an ACPI driver, which comes later in time.
It seems an odd choice to me, to use small contacts, and then use a lot
of them. Fair enough, I suppose, if you're feeding power through an
existing multiway connector (though many connectors, e. g. DIN 41612,
manage fine with varying pin sizes - I suppose not really on if you're
using ribbon cable, though, as you'd need special ribbon), but in the
case of the SATA connector, it's a separate connector anyway, so why not
just use bigger pins! But it's settled now, so I suppose we're stuck
with it. But I share James's dissatisfaction with it - the power
connector being bigger than the data one, without it being obvious
that's the reason because it has bigger pins, feels odd.
It was designed as a backplane connector, with the 7 and 15 portions
in a fixed relation to one another. Kinda a 22 pin connector with
a gap. The wafer design means it can be made as cheaply as
USB. Just extend the PCB of the hard drive, to make some contacts.
While the personal computer application rates the connector
at 50 insertions, I would expect the backplane application, with the
extra guidance provided by the packaging, the insertion count would
be a lot higher. The backplane doesn't have to do any "pinching"
to hold the connector on.
