Re: My experiences with Visopsys install on QEMU virt disk

I do think that if I could reproduce this with qemu it would be very useful. I've got a user over in the Partition Logic forum with an apparent interrupt problem, and I'm hopeful that there's just some nuance of APIC setup (or PCI device setup, or interrupt acknowledgement) that I've missed. As I sa...

Re: My experiences with Visopsys install on QEMU virt disk

Hi Ron, thanks for getting back to me so quickly. I'm a qemu noob, so I didn't do anything other than your 2 commands: qemu-img create -f raw ./visopsys.img 200M qemu-system-i386 -m 200M -netdev tap,id=t0,ifname=tap0,script=no,downscript=no -device pcnet,netdev=t0,id=nic0 -cdrom ./visopsys.iso -boot...

Re: My experiences with Visopsys install on QEMU virt disk

I'm reading that Qemu and almost all other virtualization software has plenty of issues with interrupt virtualizations. Qemu was mentioned specifically as having such issues prior to v2.9. I'll check the version I'm using. OTOH, Visopsys v0.82 worked OK with pcnet. I think you're using VMware? Huh....

Re: Won't finish booting

Hello, OK, great, thanks for the info. I have another report (in the Visopsys forum) of a similar kind of thing with these unhandled interrupts. However he's getting it with an emulator, so I can run that here and try to debug it hands-on. I think I'll focus on that and hopefully whatever I turn up ...

Re: My experiences with Visopsys install on QEMU virt disk

when I set QEMU to use the pcnet nic, I got debug messages about interrupt handling. Here's a screen shot (sorry for the poor picture): Hi Ron. Argh. I saw a similar kind of thing with unhandled interrupts on my dev PC. That was when I (unknowingly) had my disk controller set to legacy IDE mode for...

Re: Won't finish booting

Also, can you tell me anything about the hardware? Make and model? I might be able to look up the motherboard specs. Is it a laptop?

Re: Won't finish booting

Oh, and I don't have a 'legacy' setting available for the SATA controller, only IDE and RAID. Ah right, all the BIOS vendors have their own ways of labeling things. 'IDE' is the same as the legacy mode I was trying to describe. As I said, it might be interesting to see whether temporarily switching...

Re: Won't finish booting

I've attached a pic of what I could find in the BIOS. All I see is AHCI, but no mention of 'legacy.' This was on the SATA configuration page. Is there somewhere else I should look? No, that's good, thanks. That second box that says 'AHCI' is probably the one, and that's the non-legacy setting you'v...

Re: Won't finish booting

Hi, I am trying to boot from a flash drive, version 0.9. It gets hung up at the screen attached. Looks like it's looking for a PS/2 driver or something. I have a wireless keyboard/mouse attached to my system. I want to move my Windows 10 OS to a larger drive (who knew 100 GB's was too small?!?!? :s...

Re: My experiences with Visopsys install on QEMU virt disk

Wonder if you've given much thought to UEFI? Lots :-) I've developed several UEFI loaders at work, and the Visopsys one is nearly finished ... but ... 32-bit UEFI firmware is vanishingly rare nowadays - even a few years ago - I've only ever used one, and even Windows theoretically (not really) didn...
