Hi to all, i bought this card on ebay some months ago.
Symbios Logic SCSI RAID PCI Controller Card Adapter 348-0037873A SYM8951U
This is a link to the card
http://www.ebay.com/itm/130791204336?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649

Its listed on the hardware support list on morphos website.
I installed it on a powermac G4 digital audio.
The card works fine under linux and the scsi drive i installed is recognised by linux and i can partition it format use ok.

But on morphos is like the card dide't exist when i go to the disk partition tool i dont see the scsi drive.

Anyone have any idea tips workaraound ?.

I was planning to do a monster powerpc tower using a lot of fast and nice scsi drives i have but now im stuck.

Regards

I believe the 8955u (scsi-3 RAID controller, 160MB/s) is a completely different part to the SYM53C895 (ultra/wide scsi-2, 80MB/s) which is supported by MorphOS (such as this).

That would be an 89xx rather than 89x.

Sorry for your bad luck in choosing supported parts/systems so far, if in doubt probably best to seek clarification before buying.

Will an ultra/wide scsi-2 controller handle U320 drives?

I need to ask on the forum before buying

@Jim

SCSI is backwards compatible, so it should - albeit at the reduced speed. Assuming that the device is capable of operating in the same signalling mode (LVD/SE) that the host uses. In my (albeit limited) experience devices generally have a jumper setting to enable such operation.

That's where he said he looked ("Its listed on the hardware support list on morphos website."). But seems that doesn't help when misinterpreting things, like mistaking "SYM8951U" as belonging to the "Symbios 89x" family.

Exactly that Andreas i think that 8951u was included in the 89x family.
But was wrong now i have to find a use for this card :P and it was no cheap including shipping.

Will this work, and if so is it boot able.

SymBios PCI SYM8951U SCSI Ultra2 RAID Controller

What about Raid support.

I've got U320 drives around here just screaming to be used.

Isn't the answer right here in this very thread?

Yes Andreas, it is.
I made the same mistake (but didn't buy the card).

We really could use improved disk controller support.
SATA1 and SCSI2 are not going cut it when we get a faster expansion bus.

And where are you guys digging up these old drives.

The last SATA drive I bought couldn't even be jumpered down (and failed to do it automatically).

Its going to suck owning own of those Marvell based SATA2 RAID card, and not be able to use it in my G5.

Imagine what 4 solid state drives could do in a quad external array when tied to a G5 under MorphOS.

> SCSI2

MorphOS supports up to Ultra2 SCSI, which is the successor of Ultra SCSI (= SCSI3).

Well, at least I could connect my drives.
Any leads on a compatible controller?

I'm itching to make a comparison.
I've got 10 and 15K Ultra2 and U320 drives and a 10K Raptor.
My guess is that the Sil controller and drive losses.

Yes. And btw, I see that I had corrected you on the Ultra2 SCSI vs. SCSI-2 confusion before:

> Any leads on a compatible controller?

Didn't you own one with a compatible 53C895 chip a while ago?

Anyway, doing a better research and having a look into the relevant user's guide reveal that the thread opener's 8951U card (which you asked about as well) indeed *has* the 53C895 chip. The confusion in this point was actually on my and boot_wb's part (mixing up card names with chip names), not on the thread opener's. Sorry for this.
I've found old reports here on MorphZone from people successfully using an 8951U card with MorphOS on a Pegasos II:

https://morph.zone/modules/newbb_plus/viewtopic.php?topic_id=1709&forum=9

So the 8951U card *should* work with MorphOS. As to why it doesn't for the thread opener, I don't have an idea.

Thanks for the information, maybe this card for some reason have different PCI hardware ids and the scsi driver don't load?, theres is a way to add the hardware id of this card to the scsi driver so i can force it to recognise the card ?.

None that I'm aware of, unfortunately.

I'm looking all over for that controller.
I looked in my PC, but that has an LSI U320 controller in it.
I have about five different SCSI controllers, but only one is MorphOS compatible.
I wish my Inventory of parts was indexed as well as Andreas' mind.

Maybe it helps you to know that it is an 8952U card? :-)

Thanks Andreas,
But what would really help is having everything more organized.
I'm posting excess stuff over on Amiga.org to get rid of it.
For some reason, all I can find are the LSI controllers (which are Marvell/ARM based and kind of neat), but they're not what I'm looking for.

At least with all this searching I found another Silicon Image based SATA controller.

Just to make sure you are not overlooking what you search for: the SYM8952U was later sold as the LSI8952U ;-)

YES! That's it.
Located and ready to go in my Quicksilver.
Have I ever told you what an asset you are friend?

Now when I give this to Steven up in Philadelphia it will have a 10 or 15K drive with a fast controller.
This will be much better then relying on the Quicksilver's ATA66 interface.
I also upgraded the DVD-R drive to a DVD+-R drive (from a G5).

So he'll get a system with a 1.33 GHz processor, 1.5 GB of memory, Radeon 9800Pro video card, Sound blaster Live, and an Nec USB 2.0 card.

Remember folks, when we upgrade, we have the opportunity to spread the love.

Both of my Power macs are going to people who will put them to good use.
And I'll still have a Powerbook and a G5 Power mac.

> YES! That's it.

Superb. Sometimes the most useful remarks are the ones made in jest :-)

> Located and ready to go in my Quicksilver.

Fine. Now you can perform the test you talked about 3 years ago and report back :-)

Oh man, if I have to go back that far and follow through with all the disarrayed various ideas I had I'm going to need a few more years to finish all this.

First, I've got to get out the R300 cards I've promised (seven total).

Second, I've got to finish setting up an MDD development system for Eric to work on porting Libre Office.

Then, third, I can get around to re-installing an SCSI drive in my Quicksilver.

Never mind all the other ideas I've had that I haven't acted on.

And, maybe after all that is done I can screw shut the open case of my now functioning Powerbook and get it back together.

At this rate, guess I'll have those tests ready for you...in the Spring?
Probably about the time I can sit down and actually use a MorphOS equipped computer.

At this rate I'll have to start working on a G5 by then (I've already got the memory, had drives, and video cards for that already).

When I started this as a hobby, I never suspected it would grow to eat up so much of my free time.

In my opinion having scsi support on a morphos mac is a very nice option.
Fast scsi drives are very cheap this days and are trow out
