As far as PCI passthrough, I was able to get a Geforce card working with IBM SLOF on the p-series machines in Qemu. However Openbios lacks some of the .words needed, I've been hoping someone with more programing knowledge would help in implementing the needed @config .words for Openbios.

I did test a PCI Firewire card, in a PCI-E to PCI adapter and that worked great in both OS 9 and OS X in Qemu. Tho my host system refused to boot with a PCI Radeon 9200, so I was unable to test that with Qemu.

Until we add the needed .words to Openbios, the only video option other than Qemu-VGA would be a Voodoo2 PCI 3D card. I'm still trying to find one at a reasonable price for testing, unfortunately the price on them keeps going up.

If anyone has one they'd like to donate, or sell cheaply, that would help the cause. :mrgreen:

Hi,

I created new sound enabled (screamer) builds for OSX and Windows.

OSX: viewtopic.php?f=34&t=8848#p52104
Windows: viewtopic.php?f=34&t=9028

My current experiences with them are:
-The windows build performs slightly less well compared to the OSX build.
-You need the most recent Quicktime and iTunes installed in the various guests for best performance.
-10.4 and 10.5 guests can play internet radio with some crackling (like playing an old scratched record).
-Starting the sound control panel in OSX guests when already playing music creates havoc in the audio stream.
-Moving the whole window in which the guest runs disrupts the stream in Windows host, but not in OSX host.
-9.x are still the best for audio playback.
-I experimented with various variables available for controlling the audio, but haven't found a perfect mix.

Please report your experience,

Best,
Cat_7

Do you happen to have a link to the source that was used to create the binaries? Has any attempt been made to build them on 64-bit Linux? Just to clarify, the screamer builds do have a hard requirement on iTunes and QuickTime for audio support?

Hi,

The screamer source code is at:
https://github.com/mcayland/qemu/tree/screamer

I build on Linux regularly, but the sound performance is no better there.

iTunes and QuickTime are not strictly required.

Best,
Cat_7

Not sure what I'm doing wrong. I've got iTunes 2.0.4 and Quicktime 6.0.3 installed under 9.2.2. Audio is glitchy at best and most of the time is nonexistent completely :sad: This has been the result for every screamer build. This is my one tiny problem with Qemu. Everything else is awesome. Never thought I'd be running 9.2.2 like this. If I can figure out the audio problem, it'd be almost perfect.

Here's my Qemu launch command:
Code:
#!/bin/bash
cd "$(dirname "$0")"
./qemu-system-ppc64 -L pc-bios -boot c -M mac99 -cpu G4 -m 1536 -prom-env 'auto-boot?=true' -prom-env 'boot-args=-v' -prom-env 'vga-ndrv?=true' -drive file=MacintoshHD.dmg,format=raw,media=disk -drive file=AdobeMac.dmg,format=raw,media=disk -netdev user,id=network0 -device sungem,netdev=network0 -device usb-mouse -device usb-kbd

I'm having an intersting issue: with the new build, -rtc base="2000-12-25",clock="vm" is being ignored, which is a problem for the OS X Public Beta. -rtc base="2000-12-25",clock="rt" returns the same result -- "OSXPB has expired".

Anyone know what might be going wrong? This works fine in all other builds of qemu I've tried.
