S-ATA & P-ATA booting

B

barrowhill

I've just taken delivery of new PC for my son. Confirmed and checked all in
working order and opened case up to have a nose around

PC is based on foxconn 945P7MD mobo running Dual core Pentium-D. My son's
old PC is P-ATA only and he has 1TB of disc capacity potentially available.

The new PC has 4 x S-ATA connectors with one used (160GB XP pro installed).
The board also has 2 x P-ATA (IDE). One IDE has a DVD writer connected
leaving space for say another DVD device and a couple of HDD's in
master/slave configuration.

How is the boot order specified if requiring to boot from P-ATA and not
S-ATA ???? and is it possible to set for dual boot; first P-ATA then S-ATA
(or vice versa)

Advice appreciated

If you have a look into the BIOS settings you should see the various options
for booting.
Not too familiar with the 945 chipset but my Nvidea chipset mobo Bios allows
me to set either PATA or SATA drive to boot from as well as drive boot
order...1st choice. .2nd choice.
If you are contemplating adding the 1TB HD to the new system and just dual
booting in that manner you would need to enter the BIOS each time to chose
which HD to boot from. With a HD from another older system installed in this
manner all of the drivers required would be missing/different...a repair
install of XP would be necessary.
This can be done with either the SATA disconnected which would result in
each drive (SATA and PATA) having its own Master Boot record and you make
the choice via BIOS of which drive to boot from.
or with the SATA drive connected and I believe then XP would create the Dual
Boot on the SATA drive and the choice for which OS to boot into would come
up as part of the normal booting process.Be aware that this repair
installation might ask for the SATA drivers for your mobo....and will only
look for them on a Floppy drive.
hope this helps

Peter,

Thanks for your quick response. Your points are noted. Having repacked PC
to take to my son, I can't review BIOS settings/options. This will have to
wait till weekend.

I'm a bit concerned with your last point.........quote......Be aware that

New PC wasn't supplied with floppy, though one could be installed. How come
repair install not looking for CD/DVD ??? Motherboard supplied with
drivers/Utilities on CD-ROM

I didn't find a match for the motherboard model number. Foxconn uses really
long part numbers, and has variants of the same board.

http://www.foxconnchannel.com/support/downloads.aspx

You state that the board has two P-ATA connectors. If the motherboard uses
ICH7 Southbridge, that has support for one P-ATA port. That could mean
the second port is supported by another chip (which could well need a driver
if used). It could mean that one IDE port needs a driver and the other one
does not. The physical placement of the connectors may hint at which is
which. To find out more, the motherboard manual (which you can download,
rather than unpacking the computer documentation) can be used to see what
hardware is listed. Whoever built your system, likely used the ICH7
connector for the DVD, for best compatibility. Sometimes, the alternate
chip doesn't "play nice" when asked to boot ATAPI (optical) devices.
ATA (hard drives) aren't as cranky.

Intel Southbridges do allow using a Microsoft driver for Southbridge ports.
Options that the Intel Southbridge might offer are (vanilla, AHCI, RAID),
where I don't remember what the ordinary option is called. AHCI and RAID
require drivers (F6 and the floppy). If you have WinXP SP1 or later
Windows installer CD, there should be a driver that can work with a
PCI mapped port, which is what native mode on the Intel Southbridge
looks like.

If you look at this document, page 11, newer storage devices are PCI
mapped. And I believe the driver in SP1 supports that. The Legacy
option is the way motherboards used to be made - with exactly two
IDE connectors and up to four disks - it is I/O space mapped, uses IRQ14
and IRQ15, and older operating systems understand that mode out of the
box. The native mode would not be understood by an older OS, but native
mode supports more drives total. If selecting AHCI or RAID, those are
things that WinXP would not have drivers for, and you'd need the
driver floppy for them. (Before dismissing the RAID option, if there
is any kind of a future plan to use RAID, then a RAID driver can be
installed with just the one disk present. The Intel RAID software
allows migration to RAID configurations at a later date, as long
as the original disk had the RAID driver, and the BIOS was set
for RAID. If selecting to go "vanilla" at this time, that makes
RAID migration a lot tougher in the future.)

(Some background on SATA on the Intel Southbridge)

"RAID ready" is mentioned here, but without further elaboration

"What is a "RAID Ready" system?"

For floppy diskettes, when you look at the motherboard CD, there
will be something like a "makedisk" utility on the CD. When you
run that, it prompts for a blank floppy, you insert the floppy and
it makes a driver floppy for you, complete with txtsetup.oem at
the top level. That is what you'd offer if drivers were necessary.
I suspect you'll be able to get by without it, perhaps without
even needing to modify the default BIOS settings. But the only
way to be sure, would be to get the exact motherboard model number.

So, yes, there is some trivia involved :) And motherboard
manuals usually do a poor job of explaining the options.

If I were going on a road trip, I would steal the floppy drive
and cable from my own computer, and pack it in my luggage, plus
a few blank floppies. Actually, I wouldn't try to do anything
to a guest computer, unless a second perfectly working computer with
Internet access was present, but that is another story. I'd
want to be prepared for anything, because driving back and forth,
sucks :)

Paul,

Apologies for delay in responding - been away for a while. Thankyou very
much for such a detailed reply. I think I've followed most of it!. Thanks
also for links to further reading. These will be interesting to follow up
