Re: Visopsys 0.84+ (2019-08-09) cannot detect a harddrive

APIC, or just an old PIC? Small bump ;) How could I get more debug info for you? Hi qmastery, sorry for the delay. I guess I was in transit to Australia, in Hong Kong, and I saw this but didn't have my dev environment available, and then forgot about this! It's normal for several PCI devices to sha...

Re: Visopsys discussion forum

Hello admin, Thanks & congratulations for this great forum. I would like to know if we can use Visopsys for different pc games like Destiny 2, Fortnite, Minecraft ? Hello and welcome, No, Visopsys is a different operating system and not specifically a gaming platform. Theoretically yes if the peopl...

Re: Visopsys 0.84 - [NEW INSTRUCTIONS] Init failed while booting as a Virtual Floppy from coreboot/SeaBIOS

OK! So this works for me - what do you think?

I'll need to remove some debugging messages and do some polishing, but I think it's looking good.

Re: Visopsys 0.84 - [NEW INSTRUCTIONS] Init failed while booting as a Virtual Floppy from coreboot/SeaBIOS

All your stuff works well for me and I'm up and running, so now I'm working on the code part - thanks! The kernel side of things should be fairly straightforward with the existing ramdisk driver, but there's a bit of BIOS OS-loader work to do. That's all in assembler which I (thankfully!) don't have...

Re: Visopsys 0.84 - [NEW INSTRUCTIONS] Init failed while booting as a Virtual Floppy from coreboot/SeaBIOS

Alright, I'm finally free to try this. The last bit of UTF-8 work made it obvious (if it wasn't already) that the text editor needed a massive re-write. Text editing is one of those things that's a lot more difficult and complex than it sounds. I should have some kind of response soon, even if it's ...

Re: Bug reporting thread

That's great, thanks. Curiously, they all seem to have the same interval. That kind of suggests some things to check out. The number bInterval in the interrupt-in endpoint descriptor says the maximum rate that the controller should poll the endpoint for data. For a low-speed device 10 means 10 milli...

Re: Bug reporting thread

More good detective work, thanks! Earlier I suspected the interrupts, just because that's a common kind of problem. With your latest discovery about moving the mouse, that suggests that the keyboard is generating the data, but the controller is not firing the CPU interrupt when the keyboard packets ...

Re: Bug reporting thread

Ok, good sleuthing. Can you run the Visopsys 'Devices' GUI program in 'Administration' (preferably on both the working and non-working systems) and expand the tree - the USB controllers should be on the PCI bus - to where we can see the keyboard(s) connected to a particular controller, with all the ...
