I do it when workbench start ... in case you can boot without startup sequence add the stack and do loadwb

this is my working amigaos install cd
qemu-system-ppc64 -M sam460ex -device ide-cd,drive=cd,bus=ide.0 -drive file='/home/gigi/Sam460Install.iso',if=none,id=cd,format=raw -display gtk,gl=on -m 2G -device ide-hd,drive=hd-drive,bus=ide.1 -drive file='/home/gigi/amigaos.img',if=none,id=hd-drive,format=raw

just tested not stack issue... are you using last qemu version?

I'm using qemu-4.1.0-rc3. Should I be pulling from the git master?

No joy. I get the same guru using David Gibson's repo. Meditation 80000004, which I think used to mean invalid memory address or something. Not sure how that works with OS4 honestly.

@Samurai_Crow

Qemu with PPC emulation on a V4?? Yeah, that sounds very achievable....

@tlosm

I will try this tomorrow, thanks.
edit:
I tried it anyway it does not like sdl and now it does not like format = raw.

edit:
I downloaded the latest SDL dll for win10 64bit.
Where do I need to copy this, I if I need?

@Trekiej

this is a Zoltan Email to me hope helps issues



Your QEMU command lines work but sdl,gl=on may not make much difference as
3D is not emulated so this only decides how the screen is drawn which will
be slow anyway due to being rendered by guest (simple framebuffer) so gl
proabably does not help much other than introducting potential video card
related problems so maybe -sdl is the simplest way.

Also your morphos command line has a few unneded options that could be
omitted to simplify it: -cpu G4 is the default so not needed, -net user
also not needed for same reason. -device rtl8139 works but the default
sungem netowrk card should also work so likely there's no need to use any
network options just set up the netowrking correctly. Some people said if
it does not boot after installation they've fixed that by booting from CD
and copying default network config from CD to EnvArc or something like
that, I think it's somewhere in comments on my qemu/amiga page.

Setting the stack 2000000 may not be needed, maybe only for some apps but
I don't think it helps with the crash. That seems to be related to how
things happen to be in RAM so changing memory size, startup-sequence or
using different filesystem or block size when installing may affect it.
Stack size indirectly also but only if you can put it in startup sequence
and then I'm not sure it's changing startup sequence or the stack option
helped maybe other change would have same effect. This crash is mentioined
on my page in Known problems #2 but I don't know why it happens and how to
fix it. I'd need help from AmigaOS4 developers but they probably need a
simple way to reliably reproduce it with the least amount of software
running (like during boot) otherwise it's hard to debug. This probably
means there's a bug that happens randomly so even if you don't get it
during boot it can happen later any time or cause random memory
corruption. Unfortunately I don't understand what may cause it so no way
for me to fix it.

For building from source no need to build all targets if you only want
mac99 and sam460ex so adding --target-list=ppc-softmmu to configure would
cut down build time to only build qemu-system-ppc (or use ppc64-softmmu if
you want G5 as well but that's not working very well but you may try on
Linux with KVM for Linux guest). Also you can disable some thing you don't
need such as --disable-gtk --disable-tpm then you don't need to always say
-display sdl as that will be the only one compiled in.

As for needed minimum versions my qemu/amiga page clearly says what is the
minimum required so I don't know why people even try with 2.x. If that's
what their LTE distro gives them update to a newer distro version if they
can't compile it.

I've forwarded reports about the Windows serial assert crash to Stefan
Weil (I've told people before to report it there but looks like no one
bothered) so this should now be fixed in final 4.1.0 release next week.
Also QEMU 4.0.0 had some AltiVec bugs so maybe best to use 4.1.0 for
mac99.
