Here’s a weird one. While running Borland Turbo C++ in a VM on UTM/QEMU, every cursor keypress appears to jump 2 lines. A quick Google found this post, and there’s a QEMU flag that you can add to your VM settings to apply a fix for this behavior:
-global i8042.kbd-throttle=on
The key x86 hardware spec in UTM for DOS, Windows 3.1, 95 and 98 guests in order to get CDROM support appears to be this 1996 one:
If you pick the 2009 PC, most installers will fail when you get to the MSCDEX CDROM drivers.
Let’s attach the floppy disk images and start it up!
Done!
A while back I was playing with UTM to setup an x86 VM on my M1 MacBook to install Windows 98 from an iso. I got as far as booting and starting the install but then ran into issue with the MSCDEX driver on subsequent boots during the install where it would no longer see the virtual CDROM drive and so could not complete the install:
From some additional playing around, it seems there is a major difference in the virtualized x86 PC hardware between this x86 2009 option which has the CDROM driver issue:
and this older 1996 version which does work and the install will complete successfully:
A couple of additional findings:
In the Input settings disable USB input (the default is USB3.0 support) and this will give you a mouse:
Success!
Virtual PC 7 for Mac OS X comes with a preconfigured VM image for Windows XP. The approach for installing from disk image (.iso, .dmg) files instead of physical media is not so obvious, but here’s the steps that worked for me.
I’m installing on Virtual PC 7 on OS X 10.5 running on a dual G5 Power Mac.
Select the ‘Install from a Virtual PC for Mac CD’ option:
Next you’re prompted to install the install disk:
At this mount if you double-click the first of the .iso images for Virtual PC, it will mount the disk image, and should appear in Virtual PC:
This step seemed a bit flakey for me. If it doesn’t work, unmount the image, close Virtual PC and try again. I also noticed that it doesn’t work with the .dmg images, only the .iso images.
If it does pick it up, you’ll see in Virtual PC it shows the XP Pro disk is inserted:
Press Continue and it starts installing:
It only take a couple of minutes:
When it prompts for disk 2, double click the second of the .iso files:
Once installed, you’re ready to start up the VM:
XP starts up and you can continue through the XP setup steps:
Done!
