Hi Andy! Hope you're doing well. This is a sequel of https://visopsys.org/forums/viewtopic.php?f=3&t=292 thread. Old testing instruction there got broken, so I made a new one for you - much more user friendly! Simply get this archive - https://github.com/informer2016/shr/raw/master/visopdebug.zi...

wow Andy, my sincere congratulations to you !

This is done now, for release in 0.84 or 0.9 (whichever comes first!) Huge thanks to you, Andy! I am going to make a 2.88MB Visopsys floppy sometime in the future (since this rare "ED" floppy format is also supported by coreboot/SeaBIOS ) and your change will be really helpful for making ...

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...

It seems to me that this Error:kernel process:kernelDisk.c:identifyBootDisk(2081): The boot device could not be identified is the main problem that causes to fail kernelInitialize(351) and kernelMain(90). Please could we just print a warning message for the identification of BootDisk and just conti...

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 "virtu...

Finally I put Visopsys 0.83 inside that open source coreboot BIOS of AMD Lenovo G505S laptop - https://visopsys.org/forums/viewtopic.php?f=3&t=281 - and tried booting it ! ;) However I am getting the errors below (re-typed from a screen by hand) , - and I can help you to debug them if you could ...

. 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...
