I got interested by @jdog320 trying to run amithlon within qemu and by the fact that i don't have an amithlon computer and that the latest version of virtualbox just doesn't support it. Multiple reasons to try it with qemu. Looks like there is a problem with ide and i tried with both kern310 and kernel4 but CD doesn't work. Ide controller is piix3 and it is supported by the kernel (otherwise cd won't show up at all). Some problem for sure.

I am bit rusty with setting things up so thanks to @SnkBitten for helping me to set the build environment. I managed to get it working and to start amithlon with CD and both bigird and smallird inside qemu. I was using scsi driver from the kernel. Amithlon is running just fine, both hd and cd attached to the same scsi. I am doing some tests with vmware video card, second attempt, because the first one ended badly :-) It boots fine. There is no accel, just to see to get it initialized first. I will try then to get it accelerated. If anyone is interested I can write how to get it running under qemu (my version is 6.2.0).

All the best and Happy New Year to everybody!

Hi Milanca and welcome back. Please do share a write up. I'm a keen KVM/Qemu user and would love doing GPU passthrough to Amithlon VM

You can use Virutalbox for Amithlon with all features working (USB, Network, AHI) except for hardware accelerated graphics. You just have to use an older version. "VirtualBox-6.0.24-139119-Win" works perfectly.

https://download.virtualbox.org/virtualbox/6.0.24/

Just configure it as a DOS based system, 16MB video card, 1 GB ram and IDE drives. Audio setup as ICH AC97 and network depends on the kernel you plan to run.
Kernel4 set your adapter type as Intel PRO/1000 MT Desktop and Kernel 3.10 set your adapter type as PCnet-FAST III. I attach it as a bridged adapter on my host computes NIC so I can access my internal stuff (wireless printers, NAS storage, etc..).

Thanks @SnkBitten. Yes i read in your previous post that it works fine using that version. Unfortunately I can not use it (at least currently) which will require me to downgrade currently installed VBox. As I am a developer by trade I have some projects (some of their parts) which are under vagrant (and virtual box) and segments are on CentOS. I am afraid not to break it. Not sure if it will all go smoothly so I am not keen to risk. That's why I wanted to try it with Qemu.

It is actually not going well with Qemu. I am not able to get any mode other than builtin 640x480, even in vesa, and i tried with all available video devices in qemu which are supported by kernel. Vesa mode is working but only in 640x480. Ati rage 128p was promising but its support looks minimal. I spent a weekend messing up with it, it was fun though, but I'd suggest staying away from amithlon in qemu (which is great by the way). Looks like that amithlon doesn't like virtual video devices at all. Could be that i missed installing something, all amithlon updates are installed. Anyways, if anyone wants to try running amithlon in qemu here is the way I am running it:

Code:
qemu-system-x86_64 -machine type=pc,accel=kvm \
-m 768M -vga vmware \
-device dc390,id=scsi0 \
-device scsi-hd,drive=drive0,bus=scsi0.0,channel=0,scsi-id=0 \
-drive file=path-to-hdd-image.vdi,format=vdi,if=none,id=drive0 \
-device scsi-cd,drive=drive1,bus=scsi0.0,channel=0,scsi-id=1 \
-drive file=path-to-cd-image.iso,if=none,id=drive1
Here I am using image from virtualbox(which is supported) so the format is vdi. So make sure to use appropriate format, raw,qcow,etc.

The way drives are added to scsi
Code:
-device dc390,id=scsi0 <-- here we set scsi device id=scsi0
-device scsi-hd,drive=drive0,bus=scsi0.0,channel=0,scsi-id=0 <-- here we set scsi hd drive=drive0
-drive file=path-to-hdd-image.vdi,format=vdi,if=none,id=drive0 <-- attach image to drive0
Kernel to use for qemu is attached.

Best
