Hi hooptydoopty
The problem that Ron was having over in the Visopsys forum seems to have been transient, and I can't reproduce it either.
I started looking at your description of your system. This 'Bolton' chipset triggered a memory, and a search of earlier posts turned up this:
https://visopsys.org/forums/viewtopic.php?f=3&t=400
which was similar and motivated me to spend a bunch of time to sort out the APIC driver and interrupts for the 0.85 release. I never did fully get to the bottom of some of the things I saw, however.
In your case, it looks like things start to go wrong during the detection of the old-fashioned PIC interrupt controller, which normally happens just before detecting the modern APIC controller. It might be interesting to disable the PIC initialization and see whether that's the key to these mysterious problems (on AMD boards, seems like -- my dev workstation is one of them). Would you be able to test a custom version?

Hi Andy,
Sure, I'll be happy to test a custom version. You'll have to give me some details how to run it, what to enable/disable, etc., as I do have some PC literacy, but can't say that I speak it fluently.
Thanks,
Franz

Hi Andy,
I know we've gotten caught up with the situation regarding the virus. Hope all is well on your end. If you have still have time to whip something together, I'm willing to give it a go.
Thanks.

Hi hooptydoopty,
Sorry for dropping the ball on this one. Yep, life's been a bit different lately! Although I did manage to get a big 0.9 release finished in April. Since then I've been pretty occupied with other stuff. When I've been working on Visopsys, it's for a fairly major, necessary change to the multitasker/scheduler. It's tough going though. With that stuff, until you get it completely correct, the system just goes BOOM pretty quickly.
Give me a little time to get my head back into this problem. I think all I was planning to do was disable that legacy PIC code. I'll need to give it a go here, and make sure that I think it should work.

Re: Won't finish booting
Bear with me -- just doing a bit of maintenance/prep work first
Re: Won't finish booting
Hmm. I'm trying this out - skipping PIC initialization. It works fine in a VM, but not so much on my dev workstation.
If I can get something working, what format do you prefer to try? ISO image?
[ EDIT: I see that you've earlier stated a preference for USB]
