I'm annoucing the first release of my own distribution of Visopsys, think of it as my personal playground, where I try adding features or fix issues I find. It's not at the point where I really wanted to make a first release, but well, I thought it was better to do this release than making it linger...

Visopsys 0.75 does not boot successfully on QEMU (tested on 2.0.0 and 2.1.0), it stays still while waiting for IDE drive interrupts.. (as compiling the kernel with debug enabled reveals). I did a bit of research and I found the culprit: it is the APIC support that was added in this very release. Vis...

About copy-boot and bootable images It is unfortunately not normally possible to build bootable Visopsys images on non-Linux platforms. The problem lies in the following piece of code in the setOsLoaderParams() function in src/programs/copy-boot.c (the source code for the copy-boot program, which co...

I think it's better keeping this as an extra - the base system needs to be as small as possible, in my opinion. If package management is to be implemented, I think it needs to be as lean and unobtrusive as possible... packages will need to be mostly self-contained, i.e. requiring (almost) no depende...

This something I've been working on lately. NineGB is a port of the Nintendo Gameboy emulator shipped with the Plan9Front operating system (a fork of Plan 9 from Bell Labs) to other operating systems, started by me. The emulator's not very accurate and the sound emulation is disabled because it's cu...

The network stack only implements IP and UDP currently and supports the AMD PCNet network card (which QEMU emulates). That's enough for simple protocols like telnet, but many things require TCP, which is not yet implemented, due to data integrity that TCP provides. As such there is currently no web ...

What version of QEMU are you using?

Just a thought, it may probably related to an issue Visopsys has when reading from some CD drives.. if the computer you want to boot Visopsys on is a testbed, and used only for tests, you may consider swapping CD drive for the time being; otherwise the best course of action is to boot Visopsys on a ...

By the way you can add Italian to the list of translations, as I'm currently translating the strings. One issue I have found is with prompts - prompts to enter Yes/No, etc. - there is no way to change the keys that must be pressed in order to answer the prompt. For example, instead of 'Y' (yes) and ...

Right now it appears that the way most people use to compile applications for Visopsys is to place the code in the Visopsys source tree, and let the makefiles in there do the work; while that is fine if you are coding an application that is going to be contributed to Visopys' core system, for many a...
