Actually, no: To fully use 160GB ATA drives, whatever device is on the other end of the ATA bus needs to actively support 48-bit address mode. In for the two cases you tried, that means
IDE: The kernel IDE driver needs to support 48-bit addresseing to support 160GB.
SCSI: The firmware in your IDE<->SCSI Adapter needs to support 48-bit addressing.
So, while the symptoms are the same in both cases the problem is actually in two completely different places.
Most probably, you can't do anything about the IDE<->SCSI adapters firmware; however, you can do something about the linux ATA driver: code is in the 2.4.19-pre tree, it went in with 2.4.19-pre3.
Bye, Martin

But which IDE controllers support 48-bit addressing? Not all of them? Does
linux IDE driver support 48-bit for all of them? Do they require BIOS
upgrade in order to operate 48-bit?
Or can I just grab a 160GB Maxtor and 2.4.19-preX, stick them into whatever
box I have and be done with it?

You need an IDE controller that supports ATA133. For most existing
computers, that is going to require a new card.-----Original Message-----

No, you need a host that is capable of 48-bit command set operations.
Only a few hosts fail to support the double pump of the taskfile
registers, and it requires a control register for high ordered bit
operations.

Rubbish! The drives are backwards compatible with all ATA standards (do a
hparm -i on the drive and you will see). I certainly don't have an ATA133
controller and use one of the new Maxtor ATA133 drives just fine on it.
For LBA48 support I am not too sure whether you need a special controller
(for what it's worth I use a Promise ATA100 controller and it works fine on
my Maxtor 120G, LBA48, ATA133 disk but the disk is possibly not big enough
for any problems to manifest).
Perhaps Andre (cc-ed) could shed some light on this?
Best regards,
Anton

For ATA133 you need a new controller if you want the 133 MB/sec speed.
But the drives will work with any lower speed controller just fine, and
the speed difference is not really noticeable.
For LBA48 you don't need any special hardware, just support for it in
the kernel. So even an old PIIX4 will do just fine. The onboard BIOS may
refuse to boot from that drive, though.

True.

Nobody should take for granted, that LBA48 mode works flawlessly on any
IDE controller chip. In fact it doesn't! While you may safely assume
that LBA48 addressing is fine with PIO mode transfers, there are
controller chips out which simply fail with LBA48 in DMA mode (like
almost all ALi chips) or need "special treatment" (like Promise Ultra66
or pre-TX2 Ultra100 ) - there are probably more.
[BTW: the Linux driver's Promise LBA48 workaround will fail in
non-Ultra DMA mode because it is hard-wired for Ultra DMA only].
>Perhaps Andre (cc-ed) could shed some light on this?
Let's address a larger audience :-)
I've added an additional column to my "IDE drivers capabilities,
features and bug list" which summarizes my tests with LBA48 DMA modes.
A "?" means "no test conducted" (usually because of lack of hardware),
a "x" means supported, a "-" means "unsupported". and a "x!" means
"supported, special treatment required".
If there are people with hardware which still has a "?" I'd like to
hear of their experiences.

AFAIK the BIOS is out of the picture. Most OS son't rely on the BIOS
for regular operation.

It *might* work, but your mileage will vary.

For some reason, my 160G disks work on the "native" controllers, but
not on the promise cards that I bought for the purpose... After
figuring this out I haven't taken the time to find the root cause, as
I'm just a user in this respect...

I seem to remember something about new Promise BIOS's that fix that
LBA48 issue. Try updating the bios, and see what happens.
Looking at their bios page, I see the Ultra 100 TX2 supports LBA48, don't
see any info on the Ultra 100, Ultra 66, etc though. I believe the 133
TX2 has it built in.
Hope this helps,
Mike

ALL IDE controllers support 48-bit addressing. Actually, they don't need
to know about it.

Yes, since 2.4.19-pre3 as far as I know.

Only if you need to boot from the drive and then you still can boot from
the first 140 megs or so.

That's it, yes.

Sorry this is not correct, I have a list that fail.
However I need to compose a test to revoke their 48-bit operations
regardless if the device supports.

Care to bless the mailing-list with the names of the chipsets that have
trouble?

If you have a list, then the test is quite easy, ain't it?

Hi Kevin,

That actually turns out not to be the case.
While you do need a new controller if you want to use ATA133, the LBA48 addressing scheme in no way depends on ATA133. Running a 160GB disk on your old ATA100 (or ATA66 or ATA33) controller works just fine.

Unfortunately, I was recalling some article I read last year that said you
needed upgraded firmware (such as upgraded motherboard or new PCI card) to
get > 137GB support. I should have verified that my information was still
correct.
And here I made sure the motherboard I bought this month had 133 support so
I could use future large hard drives on it :) At least I finally have
support for my ATA100 drives at something faster than ATA33.
