other possible location for shortcuts:
c:\ProgramData\Microsoft\Windows\Start Menu\Programs\MSYS2\

(if they are in graphical start menu at all)
if you do have the shortcuts there you can check their location by right click -> choose properties

.exe is ok too

That worked really well! Thanks again @robertmo3!

How come the dlls it needs to run aren't built into the same folder (build)?

The shortcuts were there, but they weren't showing up in the start menu, even after typing the whole thing.

yeah win11 search doesn't find 😉
but you can find them manually under letter "M" 😉

It used to be there, I just typed m and up it used to pop

@robertmo3, is there a quick way to build all the libraries for qemu in one go (like sudo apt-get depmod qemu) AND

do you know to specify a specific video BIOS? The VGA routines are relatively straighforward, I should be able to:
1) Define a PCI manufacturer/device ID
2) IO ports
3) Memory mapped ports (mmio)
4) VRAM (both direct at an upper address and paged into VGA segment 0xA000).

The one thing I don't know how to do yet is to replace the stock VGA BIOS and (preferably override Int 0x10, though being a VM this might not be possible).

It's got an internal mechanism in there somewhere to specify the actual BIOS data (segment 0xC000), I haven't worked out where that is yet.

c:\msys64\home\User\qemu-10.0.0\hw\display\cirrus_vga.c

1    k->romfile = VGABIOS_CIRRUS_FILENAME;
2    k->vendor_id = PCI_VENDOR_ID_CIRRUS;
3    k->device_id = CIRRUS_ID_CLGD5446;
4    k->class_id = PCI_CLASS_DISPLAY_VGA;

I missed that! I'm out of commission because of thundershowers at the moment. The breaker keeps tripping every time there's a lightning strike nearby. Aargh! It's ridiculously hot for brief periods followed by insane amounts of rain.

@Robertmo3, how do you actually run this?

qemu-system-i386w.exe with all the parameters from the qemu.bat file (with your test apps) doesn't work It just shuts down.

has qemu left any message in the cmd?

robertmo3 wrote on 2025-04-23, 10:09:

Nope. Just quits. It's running from msys2/bin.
I did a separate build with whpx support, using your original command line.

I'll have another go once the afternoon thunderstorm stops.

I've got part of the rendition_vga stuff done. I'm not sure the int 0x10 calls work because the bios is going to mess around with the registers and that won't change resolution or anything because there isn't a full register implementation, yet.

Dosbox has a stock implementation of int 0x10 which Dosbox-Rendition overrides to do some of the rendition initialisation.

does it run without any parameters?
what parameters do you use exactly?
run it from a separate folder from cmd

Yeah. Usually it's pretty dry around this time of year. When May rolls around usually the hydro-power reservoirs run out. I don't think that'll happen this year.

My command line is:
