# and puts the menu BELOW its artwork, where GRUB's default menu box used to
# cover it. Only on a graphical terminal: gfxmenu draws nothing anywhere
# else. Without the theme, the background with the theme's colours; plain

# file on a PXE boot and the theme never loaded there. GRUB fell back to its
# plain framed menu with the picture stretched behind, and that frame and the
# entry editor ran straight across the artwork. splash.jpg and theme.txt are

# The menu on the board's serial console as well as the display. EDK2 exposes
# the UART as GRUB's efi0 (terminal "serial_efi0"), so GRUB never programs
# the UART itself. But the
# speed must still be NAMED: `serial efi0` without --speed reprograms the port
# to GRUB's default 9600, and no single value is right for every machine -- a
# universal 1500000 would be wrong for any board running another rate. So it is chosen per board
# from SMBIOS type 1's product name (offset 5, the same string Linux shows as
# /sys/class/dmi/id/product_name), and an unknown board gets NO serial mirror,
# exactly as before. Only boards with EVIDENCE belong in this table:
#   ROCK 5 Model B  1500000  Radxa ROCK 5B: efi0 present in GRUB (seen on
#                            HDMI); 1500000 is the device tree's stdout-path
#                            (serial2:1500000n8) and the rate EDK2 and the
#                            kernel use. Readable output NOT yet seen: no cable
#                            was attached. Confirm before trusting it.
# NOT the GB10s, deliberately: their 921600 exists only in configuration (an
# /etc/grub.d snippet and console= arguments), and no serial console has ever
# been seen working on one -- not even which physical port carries it. Add a
# row when a console has been watched, not before.
# --append keeps gfxterm and the theme (verified on the ROCK 5B's HDMI, with
# keyboard input in every phase); same idiom as the installed GB10 system's
# /etc/grub.d/05_scutarius_gb10_serial.
