Now for something different

My band released a new EP and video in February, if you're into that kind of thing (punk rock things). I'm the singer.

Re: Visopsys 0.85 Released

Hi Ron, Ahh, ha ha, no. I'm not quite sure how I'd even go about that. The majority of the code is in the monolithic kernel, which is fairly hierarchically flat. A meaningful diagram would have to describe a sequence of things that happen at initialization. It's like a big library after that - kind ...

Re: Bug reporting thread

It might be worth trying the new 0.85 release. I did a bunch of work on the APIC driver and interrupt infrastructure, and definitely solved some problems (for example, it can now boot on my own dev workstation)

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

Visopsys gets its IRQ routing info from the multiprocessor tables (not ACPI), if that helps. By the way, your 0.85 floppy still doesn't boot if embedded to a BIOS (same errors as your previous releases), so I don't know if your special code - which made 2019-08-09 floppy working as a part of BIOS - ...

Re: Is it possible to PXE boot Partition Logic /Visopsys?

If anyone here is still interested, the newly-released version 0.85 may do what's required here. I implemented it for Coreboot/SeaBIOS support: if you create a file /ramdisk in the root of the floppy disk image, the loader will load the boot medium into memory and pass the address to the kernel, whi...

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

Sorry for the delay. The patches ended up being quite large, mostly because I'm fussy about my code, and ended up rearranging and reformatting a bunch of (mostly older) stuff. Here's your first link. This is just a debug USB image with my latest code - just in case I've already solved the problem. T...

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

Yes, I could debug it using a USB. Will be waiting patiently for your USB debug image ;) So after disabling all the PCI interrupts by default: Apparently, yes, on this machine my IDE controller is actually going wild with interrupts, and the OHCI and XHCI USB controllers are doing a few unexpected ...
