Re: Visopsys 0.83 - Initialization failed while booting as a Virtual Floppy from coreboot/SeaBIOS

Is there any way you could post some instructions about how to set this up in an emulator, such as Qemu or VMware or VirtualBox? Sure! ;) Please download and unzip this coreboot.zip - https://github.com/informer2016/shr/files/2728463/coreboot.zip ( just 574KB but too big to be attached to this mess...

The Visopsys kernel does have a ramdisk driver. Normally you request the creation of a ramdisk (allocates memory, etc) but I could add a function that takes existing memory and uses that. I'd also have to add an extra kernel parameter to pass a memory address instead of a media signature, but again...

Please could we just print a warning message for the identification of BootDisk and just conti...

Re: Visopsys 0.83 - Initialization failed while booting as a Virtual Floppy from coreboot/SeaBIOS

are there any constraints about what kind of code can run within this firmware environment? Is it OK/possible to do things like take over control of various bits of hardware? (such as the interrupt controllers, say) Hi Andy, There are completely no restrictions: after SeaBIOS jumps to a "virtual fl...

Re: Issue when getting file size

. Good day, Andy! A couple of bug reports; this is the first message (+ now with a proposed help-floppy.txt attached ) "help" command prints a quite long list of commands, however not all of these commands are available at the floppy version. Perhaps you've decided to keep the unavailable command d...
