Just a question Toni:
For UAE RTG on AmigaOS 4 its "only" needed a native PPC driver for Picasso96 (AOS4 version) or is there even more work needed? |

also winuae crashes if I do a key reset (ctrl amiga amiga) on the other way I solved the powerup problem, I run ppcinstall from cli and after that I can run powerup programs btw Toni can you check this game : http://aminet.net/game/shoot/VAxen.lha using idem workbench installation: on b12 the game run perfect on b15 when I run vaxen.elf says "Bus clock is 32 mhz" then freezes ??? :shocked |

Just a note for better performance: I recommend to use CyberStorm SCSI instead of mainboard IDE (SCSI works since QEMU PPC was added). Select "Accelerator board SCSI".
SCSI is fully DMA, software basically only needs to say "transfer this much data from block x to block y, transfer all data to/from address z", everything else is done by UAE host side code. IDE is PIO = emulated code needs to do everything "manually", (reading or writing requires word by word CPU reads or writes) and running emulated code is always slower than native code, especially JITs rarely work very fast when they need to continuously access IO addresses. |
I did another OS4.1 installation test with latest beta and SCSI: install took only 3 minutes! Previously it took about 1 hour..
I think performance is now as good as it can get. |

But most important part is line like this: hardfile2=rw,DH0:.\hdf\os41.vhd,0,0,0,512,0,,scsi0_cpuboard (only difference between ide and scsi should be scsi0_cpuboard vs ide0) |
Hm, same here. I manually modified the config file to "scsi0_cpuboard" and now OS 4.0 doesn't boot anymore. There is only the Kickstart screen.
|
Perhaps OS4 needs to be installed using SCSI (cybppc.device). If installing to IDE boot kernel won't include any SCSI drivers?
|
OK, I will give it a try.
Is it ok that my config is missing "Accelerator board SCSI ROM file"? And is it the right way to manually modify the config, because I didn't find a way to do so in the GUI. I can only add CD images but no hard drives with this attribute. Edit: Sorry, was too blind to find it in the GUI, forget my last question. |
You can install via ide, but the os4 installer will ask if you want to keep cybppc.device or not. I did keep it enabled when I installed sometime ago and can switch between ide and accelerator scsi as I see fit and the boot speed is dramatically faster in the Qemu pcc than pearpc.

EDIT: Someday useless options from SCSI list will be filtered out. |

Hey Toni. A special ROM file is needed for this to work (like te blizzard SCSI, 4091 etc) or you just select it as an option and it works? |
SCSI is always onboard of Cyberstorm MKIII/PPC boards, not optional like on Blizzard (and content of Cyberstorm ROM)

Cheers mate

This is much better than beta 15.
In OS3.1, 3.9 FXpaint still won't load. That didn't happen in the pre qemu betas. I tried the no buffering and accelerator board scsi options with OS4.0 It still takes a long time to boot but is much more usable once it does. The OS4 68K emulation now works and all the programs that work on a real Amiga with cyberstorm PPC work in emulation. A bit slower than in a real Amimga on my system--1.8ghz dual Centrino Core Duo. And speaking of the real thing, I bought another A4000D last week and just moved my Cyberstorm, Cybervision 64 and CF drive onto it yesterday afternoon and now have a working setup to do one on one emulation vs. real Amiga comparisions. I also have a faster Core Duo laptop with a much better gpu to test on as well as recently purchased I5 laptop/tablet convertible to test the PPC emulation on. The I5 is rather slow as I5s go. The thing was designed for extremely long battery use and I'm not sure how much faster than my Core Duos it will be. Log and configuration files attached from a quick test of FXpaint in OS 3.9. I quit Winuae just after trying to launch FXpaint. |
Is it possible to boot OS4.1 using Blizzard PPC yet? I've tried and just get the disk animation (OS4 kernel). Will provide logs if it's been known to work.

BlizzardPPC: not supported.
- memory mapping is not correct enough (can't have >128M) - use of Z2 or Z3 boards is impossible in real world. No one knows what should happen. |
