Thank you. So for this byte aligned (what ever it is) transfers you also get only low data rate like 1 or 2 MB/s. Maybe all my copy processes (ambient or CLI) from one partition to another are byte aligned and it is so slow on my Peg because of this?

Quote:

Wow, thats a huge block! I don't have the tools to cut this in the right size. And in the end you also need a fan on top of the cooler. So it still makes noise. But impressive cube

It is 64 on all partitions. This is the default that HDConfig sets.

I would want to have it silent

So the new pictrures all all active cooled, I think. A passive cooler with a fan isn't that active? Because the fan is active.

It says:
PCI ATA/ATAPI Driver@0: PIO Mode 4
PCI ATA/ATAPI Driver@0: UDMA Mode 5
PCI ATA/ATAPI Driver@2: PIO Mode 4
PCI ATA/ATAPI Driver@2: UDMA Mode 5

One is the CD-ROM and the other is the hard disk. So they both use 100MB/s.

PCI is slower than AGP. Can you feel it?

Quote:
I try to find them.

Yes. Graphics card on PCI are noticeably slower than on AGP. You can feel it.

I even tested PCI-express card through a PCI to PCIe adapter, And I switched back to my Radeon 9700 Pro which is much faster and have full 3D support. It also can handle 2K resolutions with no issue.

I use more, 200 or 300. But if you have low speed with read/write big files, I think it is not the case. Look for max tansfer value - it it limited somehow?

Quote:
It is up to you. If you have big case with good airflow, you can use this cooler without fan.
CPU MPC7447(A):
6.5W @ 900 MHz
7.5W @ 1066 MHz
19W @ 1420 MHz
ARCTIC Alpine M1 Passive RECOMMENDED FOR TDP UP TO: 35 W

I have nearby bigger cooler of graphics card and I want also have some airflow around northbridge - thus I used the fan. And yes, is is active now. But the name of cooler itself stays "M1 passive"

Quote:
OK - same values like me. But these numbers are OK for internal IDE. For SiI SATA cards you can (in theory) have 133MB/s, but MOS sata.device is show stopper here.

Quote:
Yes, overlay is for playing videos.
As a said - I do not used any PCI card, I simply don't know.
In theory - if you succeed to find (or make) some AGPx1->PCI riser ( something like reversed riser for efika) you can try PCI card in AGP slot - in such case it will have double speed - 66MHz ( compares to 33MHz of other PCI slots).

Quote:
So the PCI cards are only better for more video RAM to show more windows and screens? This would be good but if it is slower then it is not a good change. I think I only have AGP Radeon 9200P or so. Is it also faster then PCI cards?

Quote:
I don't know . I don't underdtand all these settings. I always let them on default. Only for IceFS I changed them like written in the manual but IceFS still has so many bugs that it is impossible to use - but other construction site.

Here I use SFS. And for SFS the Max Transfer is 0xffffffff and Mask (on the right to it) is 0x7ffffffe.
How big is one buffer? One byte? Kilobyte? Megabyte? How can I know the right number of buffers? Because it is the same for all partitions. For 1GB and for 120GB.
Quote:
No. I have a normal Micro ATX case. Maybe this is too small. I do not know which one is enough.
I found the cooler on amazon but not avilable. Maybe it is too old. I will look further. Funny thing: warranty 6 years, haha. It is just a piece of metal. Only a block. Nothing more. What should happen after 6 years? Break it? Melt it?
Quote:
I already use passive graphics card. But the CPU is noisy.
Quote:
I have one of the cards that work with ulsata2.device. It says UDMA6. So this seems to be good. But MOS cannot from that. Pity. Because hten I could remove the IDE disk. Or maybe the mos team should upgrade the sata.device to allow boot from it and higher speed.

Quote:
I see if I can find it. Then I can look for a 2D card with overlay.

> Overlay is only for MPlayer important?

It's also for playing video inside Odyssey as well as for many emulators (for free resizing of the window).

> So the PCI cards are only better for more video RAM to show more windows and screens?

MorphOS can't use more than 256 MiB VRAM, btw.

> I think I only have AGP Radeon 9200P or so. Is it also faster then PCI cards?

Yes, likely.

I thought OWB uses MPlayer. How is it with scene demos or SDL programs that use full screen or window resize?
OK emulators I don't need.

> How big is one buffer?

I think that one buffer equals the size of the block size set for the filesystem.

Good luck. I've never seen such thing.

> I thought OWB uses MPlayer.

It doesn't use any external program for anything unless explicitly configured to do so. Both OWB's internal video player and MPlayer use integrated FFmpeg for video decoding.

> How is it with scene demos or SDL programs that use full screen or window resize?

No idea, sorry.

Me also not. Only xserve G4 have similar 90° riser.
You need AGP 1x v1.0, 3.3V and PCI v2.1 3.3V 66MHz.
If you very need it, you have to made it. It looks easy.

It's default value, thus OK. I don't know why you have such slow speed. You can try other disk and other cable. If I copy real big files IDE <-> SiL SATA, I have around 30MB/s.

Code:
This result is file from SATA HDD(SiI controller) to SATA SSD (internal IDE+Axago IDE-SATA adapter). I don't remember, if it was before overclocking or after.

@Connor,

You have set up too few buffers for your partitions. Type the command addbuffer in a cli/shell to know how much buffers you have for all your partitions. Where have you find this value of 64 for the buffers of each partition ?

I have searched on obligement.free.fr by typing 'installation morphos' and here are the results with differents versions of morphos. At the beginnings of morphos 1.4.x with scsciconfig the buffers setup was 600 for each partition. With morphos 2.0 this value was lowered to 300 for each partition. On the article morphos 2.6/2.7 as 2.x/3.x the value is the same, 300. On most recent articles about morphos 3.0/3.9 and 3.10/3.12 the value indicated is lowered to 128 but on grabbed pictures the value is steel 300.

By tries increase the buffers value for each partition to 128 or 300 and verify how better the datas throughput are. This will take a few more memory but if the transferts are better it is not a problem.

Very nice find, I wasn't aware of this riser. The AGP side seems compatible with the Pegasos 2 and the (64-bit) PCI side seems compatible with (32-bit) Radeon HD cards. Would be cool if someone tried in his Pegasos and compared performance with the same Radeon HD card installed directly in 33 MHz PCI slot.

Last rest - I need to find new free place for photos

cooler for overclocked Radeon 9800 is modified THERMALRIGHT V-1 Ultra.

Exactly this I have in plan. I want to buy this riser, and wait for some cheap HD 4350 PCI. I don't need 3D, but want video accel, thus HD 5450 have no sense for me (yet). And if it will work and be faster then Radeon 9800, I try to produce riser that fits to Pegasos.
Right to say, that this plan is very very long-term...

Quote:

I already tried several disks. The cable is new and good. I copied from SATA one SFS partition to another SFS partition. If I copy such large files then I have to wait for hours because it only achieves (in average) a bit more han 1MB/s. It is also like this when I copy only on the IDE disk from one poarttion to another or from IDE to SATA or from SATA to IDE.

Quote:

Not I have set this up but MOS has set this up. I said "create a new partition" and MOS set all the values. I must expect that MOS knows right what the correct values are becuase it does all the detection and preparation, how can a user know this and if they are different then MOS has to inform the user about the right settings.
The value for the buffer is written in HDConfig if you click on the partition.
With addbuffers it shows that every partition has 128 buffers. Only the IceFS partitions say "unknown DOS packet request type".
I Installed MorphOS with 3.10. I added all buffers to 300 now. With a large file I get almost 4MB/s. Still very low. So there must be nother reason.

Was anybody lucky enough to boot from sii1414 directly? I just created FFS based boot partition, put the necessary stuff in, and when I come to OF and type "show-devs" I have together with others:

regarding CPU overclock. Is it possible to change the G4 on the CPU card for a higher clocked model? Don't know if they're pin compatible with newer versions.

There's been some discussion on MPC7447A and MPC7448 and their pin compatibility with MPC7447 some years ago:

https://morph.zone/modules/newbb_plus/viewtopic.php?forum=2&topic_id=6252&start=50

Even if the 7447 could be replaced by a successor part in terms of pin compatibility (which has so far not been definitely answered), there're still the potential issues of SmartFirmware compatibility and cooling.

@All
By the way, is anyone know where to check what kind of UHCI controller chip exactly pegasos2 have ?
