I thought I'd share a small success with installing Debian 12 under VMM,
in case some might find it useful. The boot parameters are "install
gfxpayload=text console=ttyS0,115200n8". I added these boot parameters
from the Debian installer after selecting the Help menu using "H", then
selecting "Special boot parameters for special machines." using <F6>.
By the way, I found an article that suggested using "vga=off" instead of
"gfxpayload=text". This worked in the installer, but hung up the boot on
the post-install, because "vga=off" has been deprecated.
This was under OpenBSD 7.4, run from an xterm. Let me know if there are
any comments or questions.
Cheers,
