Pegasos2 Tips & Tricks

[sailorMH]

Last upgrade: overclocking Radeon9800Pro:
I succeed to overclock GPU from initial 338 MHz memory a 378 MHz GPU core:

to 351 MHz memory, 392 MHz GPU core.

I also equip the card with new cooler - Thermalright V-1 Ultra, slightly modified to don't block nearby PCI slot.

even if overclockig is only by 2-3%, SDLbench faster by another 8%.

Nice! Just now, my Pegasos have overall score 3341.66 in http://hdrlab.org.nz/benchmark/gfxbench ... esult/2155
It is faster than some SAM460Ex with HD cards, even if this card have no compositing under AmigaOS.

Best 2Gb memory configuration:

I checked many ram company for add 2gb full system bosted on pegasos but the best result i had with

Serials of the rambank:
Crucial: PC3200U - 30331Z 1GB DDR 400 CL3 not ECC unbuffered (perfect woking with 2x modules)
Buffalo: PC3200U -30330-B1 1GB DDR 4000 CL3 Not ECC unbuffered (working great in second slot in couple with kingstone 3200 1GBDDR 400)
Kingstone: sorry i dont have the stick on it for know the serial

Since those Crucials seem to be hard to get, what about those: 1GB Crucial CT12864Z40B.E16TY PC3200U 400MHz DDR1 Non - ECC? Would they maybe also work?

[Reth]

So the combination of a fully functional 2GB RAM:

2x 1GB DDR SDRAM PC-2100 ECC - 266MHz (KVR266X72RC25/1GD).

What is your motherboard/firmware revision?

@All
Did anyone were able to boot from the SII314 card directly?

Tried to do this now, have there FFS "boot" partition on SSD with amigaboot, and all i can see now when do "show-devs" in open firmware:

/pci@80000000/raid@5

If i "cd" to "/pci/raid" and do ".properties" i have:

Now the question is how to boot from?

AFAIK the OF only boots from the IDE bus. It is a Peg. OF limitation. Just as the required PS2 keyboard.

@Lazy

You are wrong at least about the PS2 keyboard: I am using a USB mouse and keyboard in my pegasos2, and they both work fine in OS4 and MorphOS and even in the OF boot menu and in the OF itself.

So, you may also be wrong about botting from only the IDE bus. Someone told me, that if it can be seen in OF (as I show previously) it can boot from. Just need somehow alias it and so on.

I use SiI3114 for Amigaos and Morphos, but as lazi said, it cannot boot directly from it.

You still need booting partition on ide IDE bus, but your System can reside on SiI3x1x partition.

Configuration on my Pegasos 2:
1. CF card (with IDE->CF adapter) on IDE:0 with two partitions only :
- bootcf:, formatted as FFS, size 1GB (but 100MB is sufficient). Here is amigaboot.of (Amigaos), boot.img(Morphos), various linux kernels and bootscript. Bootscript is generated with bootcreator and I use it like boot menu for selecting between Oses.
- amkernel:, formated as SFS, size 1GB (but 20MB is sufficient). It contains only single directory - "Kickstart". You have to copy it from AmigaOs SYS:.
To avoid conflict with MorphOs with high boot priority, I recomend edit your Kicklayout (add MODULE Kickstart/BootDevice) and create file BootDevice with your AmigaOs System: device name (Echo >Kickstart/BootDevice "ADH0"). See original Docs.

2. SATA SSD on SiI3114 with other partitions
- DH0:, SFS, MorphOs System:
- ADH0:, SFS, AmigaOs SystemAOS:
- DH1:, SFS, MorphOs Work:
- ADH1:, SFS, AmigaOs WorkAOS:, etc...
3. other SATA with linux, backup, etc...

Then you can boot from OF:
boot hd:0 boot.img for MorphOS
boot hd:0 amigaboot.of for AmigaOs
you can add also parameters BD=DH0, BD=ADH0,...

This configuration works very well. Only you cannot forget to copy boot.img from System: to bootcf: after every MorphOs upgrade.
And copy SystemAOS:amigaboot.of to bootcf: and SystemAOS:Kickstart/#? to Amkernel:Kickstart/ after every change of these files.

Note: for AmigaOs you need also Kickstart directory on path visible from OF, because amigaboot.of have no driver for SiI 3114 ( MorphOS boot.img does). The driver is loaded as kickstart module, and then you can use it.

@ sailorMH

Well, it was mostly for sake of interest, as I compare the speed I got from ide2sata and connected SSD to it, and si3114 and connected SSD to it: speed about the same. So that not big sense to have si3114 as a replacement for ide2sata, only maybe in case you need many HDDs and co.

Sadly that I can't boot from through, want to just make a bit more space inside But in terms of speed about the same as ide2sata

The next step will try to overclock CPU to 1.33, ordered that tasty sip-dipswitch already

[sailorMH]

@kas1e

yes, you are right. Speed of SATA HDD or SSD is pactically the same with SiI 3xxx and with IDE->SATA adapter ( I tested Axago). But only with standart CPU clockspeed 1GHz.

Here is my old results: viewtopic.php?p=47924#p47924. Lines with red crosses are with frequency 1GHz, and they are almost equal.
Here: http://powerpc.lukysoft.cz/upgrade-pega ... mment-2116 (Czech language) is result after overclockong to 1.33GHz, and speed of SiI 3xxx is much better then IDE->SATA. The best result have PCI Promise SATA2 controller (about 115MB/s).

Unfortunatelly Promise is practically unusable with Pegasos2, you cannot boot from it. For Morphos there are 3rd party driver on Aminet, but you have to make moutlist and mount the drives after boot. For AmigaOs there are no driver at all. I only tested it and don't use it, I have no spare PCI slot.

Note: all tests was made with MorphOs, Idon't have AOS-MOS comparison.
Here is also my post on MorphZone https://morph.zone/modules/newbb_plus/v ... 1&forum=11. Interesting is, that AmigaOS recognized SiI 3xxx correctly like UBDMA6=133MB/s with S.M.A.R.T feature, but MorphOs like UDMA5=100MB/s with no S.M.A.R.T. AmigaOs SiI 3xxx driver is better on AmigaOs.

@sailoMH

Unfortunately, Promise is practically unusable with Pegasos2, you cannot boot from it.

Wait, but we also can't boot from Sii3114 as well? I mean, we can't both from both. Or with Promise one there is just a new issue about morphos you describe but in terms of "boot from" they both "useless"?
