RAID

Any way of changing this? I'd like to boot from SATA (single drive, not a
RAID), with an IDE RAID controller installed (RocketRAID 454) for my data
drives. Unfortunately, I've just discovered I can't seem to get it to boot
from SATA with the RocketRAID installed... :-(

I don't think so. I'm not sure how the BIOS decides what a SCSI controller
is and and which one it's going to use.

I've had a play with modbin and can't see anything obvious. What you
require is not impossible, but may not be user configurable in any way.

There's nothing stopping you from sticking a bootloader on the IDE drive and
using that to boot from your SATA one.

Because the SATA is external (PCI). The internal is ATA.
Only(?) Intel has native SATA with Raid support.



Nope, never has been so.



But you can with it removed?

Yeah, the Intel ICH5 (I think thats what it is called). nForce2 does not
support SATA or RAID. nForce3 supports both, AFAIK.


I think you'll find that an external ATA controller on the A7N8X will be
attempted to be booted from instead of the onboard SATA controller if you
select SCSI in the boot order.



Yes, he can.

Presumably you mean "add-in"?



Which is external of the MoBo chipset.


That is entirely possible but that doesn't bite with what I commented on,
i.e. taking precedence over the MoBo chipset native ATA controller.

If the MoBo bios choses to scan the add-in controller first and only, then
that is a flaw in either the MoBo bios or the bios from that particular
controller. It should scan all controllers, not only the preferred one.
There can be a problem though when a drive attached to the add-in
controller has the potential to be bootable but isn't (primary partition).
It may be worth a try to have only an extended partition on that drive
in that case.


So the drive is bootable to begin with. Just checking ;-).

If you prefer.


Yep.


Thats not what I said... my comments refer to the particular motherboard in
question which does not have native SATA support. Hence "onboard" and
"external" with respect to the motherboard.


You mean active?


Only active partitions are booted (only primary partitions can be active,
but you can have up to 4 of them per drive)

Could you please setup your newsclient so that is doesn't wreck the quoting?





But that is what it read.


The problem with that is that from a logic(al) standpoint, your 'onboard'
(add-on) and 'external' (add-in) are the same, they both sit on the PCI bus.


Yes and No. Yes, 'not active' should be enough to let the bios continue
searching and No, a poorly written bios may see the primary as a boot
candidate and break off the search even though it shouldn't.


Yup, that is how it is supposed to be in the perfect world.


Not with MS, AFAICT.

Whats wrong with it?

I'm using OE-Quotefix so it might look like anything for all I know.

I just undid the changes it makes... don't see any major problems, if you
expand on the problem I'll see what I can do.

Can you snip and not top post please?

:-P

Here is a test to see if quoting is still "wrecked"

How is that? Hopefully that sorted it, thanks for drawing it to my
attention.

Didn't see the bits below...





"external ATA controllers take preference over the onboard ATA controller,"

I was commenting on the onboard SATA controller, context should have made it
clear but thats my bad...


Indeed. Logically they both are. But I was talking physically, hence terms
such as "onboard" and "external" I know they both reside on a PCI bus, not
the same one in this case.


You come across any of these "poorly written" BIOSes? Got an example?


Got an example of an imperfect world?


It works fine, MS Fdisk can't deal with it, but the OSs will boot.

Single word lines caused by auto-linebreaks?


Aha, I was already wondering howcome the single word lines caused by
the autoline breaks were having the correct number of quote characters.
I didn't even check what you were using as it 'must' have been something
else than OE. Hadn't considered that it might have been an inconsistently
setup OE-QuoteFix.


I'll toppost when it is convenient and I won't snip when that's inconvenient.
I'll not toppost when it is inconvenient and I'll snip when that's convenient.
Did I leave out anything or will this suffice for you?

I wouldn't have seen them either if I had snipped them so mindlessly.




i.e. externally from the chipset, I should have added.



Not that it matters, but I don't think so, unless it has a PCI to PCI bridge.


Not really, but when this behaviour surfaces, do you have a better explanation?


May as well be the MoBo at hand.


You are correct.
The check in the MBR is on multiple active partitions,
not just primaries, as I wrongly assumed.

Multiple ones. There are 3 PCI buses and one AGP on the deluxe. The SATA
controller is on a seperate PCI bus to the nVidia one, but will probably be
the same bus as the add on promise card. Again, not that it really matters.

There seems to be a PCI bus for the southbridge, the slots (including the
SATA controller), the 3Com NIC and then the AGP slot. The non deluxe does
not have the 3Com NIC and presumably has one less PCI bus.


No... never come across the behaviour though.


The A7N8X? Doesn't happen on mine.

That's not likely.


Presumably you know this by running a PCI bus sniffer?
Not all buses are actually PCI buses. Native devices are not on the
PCI bus but because they are organized the same way as PCI, show
up as such.


Presumably that is meant to read:
"The SATA controller is on a seperate PCI
bus to the nVidia native ATA controler" ?

Yes, the native ATA controler is not on the PCI bus but similar
to the Intel ICH shows up as if it is on a seperate PCI bus.


Yes, the actual PCI bus.


The MCP2 native devices.


The actual PCI bus.


Would expect that on the physical/actual PCI BUS but maybe
it sits behind a bridge with that many devices and 5 PCI slots.


AGP is a form of PCI too.


But do you have the same bios(es) as OP?

[snip]

Or even the HyperTransport bus.


On second thought, this board probably has the MCP-T that
has the native 3Com compatible NIC.
Like the native ATA controller it appears as if on a PCI bus.
