Ilo – a Forth system running on UEFI

Ilo/Konilo is pretty cool, but I already knew that. What I didn't know about was qemu-system -nographic.

Any idea why crc is specifying a custom BIOS image? QEMU comes with a default one, right? Questions like these make me wish asciinema supported recording voiceovers.

I'm guessing that the slow text screen updates are some kind of an artifact of unoptimized UEFI implementation, and/or QEMU, because I'm pretty sure Konilo is a lot snappier than this running under Linux, even though the Ilo implementation is not a highly optimized virtual machine.

I'm not well versed in qemu's various options. When I didn't specify a BIOS image, it seems to be using SeaBIOS, not UEFI, and hangs on "Booting from Hard Disk...". I should be able to start doing proper videos soon; I've been slowly working towards that.

I can say that the display & overall performance is noticeably faster on the two actual computers I tested on than under qemu on my Linux system.

you probably should set the serial port speed
