Add support for up to 35 boot menu entries (2 pages if >18). To solve the
">10" problem currently experienced by SeaBIOS users (there are no 11, 12, etc.
keys on a keyboard - so impossible to choose the last menu entries if you got
>10 entries because of multiple hard drives / secondary payloads / floppies)
- the boot menu has been extended to the letter keys. NOTE: TPM menu has been
moved from T to M letter: it is at the end of keyboard's 3rd row of letters and
"Trusted" is adjective while "Module" is a noun; alternatively could press '-'.
Also, add support for a numpad. Small USB numpad could be really convenient for
choosing the boot entries at coreboot boards used as (maybe headless) servers.
'/' char on numpad could be used to open the boot menu or to exit it. If there
are >10 boot menu entries - the numpad console interface will be enabled: press
one or two digit keys and then ENTER to confirm your choice, or remove a digit
by pressing the '.Del' key. Also you could call TPM with '-' key at any moment,
or boot with a single key press of your fullsize keyboard.

(patch body is after the testing instructions below)
This "advanced_bootmenu" patch is much more useful when used together
with my "multiple_floppies" patch:
[SeaBIOS] [PATCH v2] ramdisk: search for all available floppy images
instead of one
https://mail.coreboot.org/pipermail/seabios/2018-December/012670.html
Sadly I haven't done the suggestions by Kevin (I have so many unfinished tasks)
so the "multiple_floppies" patch is also not merged yet. But you could install
both patches to your coreboot by executing this script while at ./coreboot dir:
https://pastebin.com/raw/hv9sSuMU
And here is a coreboot image for QEMU with these two patches applied and my
collection of wonderful and useful floppies added to popular the entries list:
https://github.com/mikebdp2/floparchive/blob/master/coreboot.rom?raw=true
Descriptions of the most prominent floppies could be found here:
http://dangerousprototypes.com/docs/Lenovo_G505S_hacking#Useful_floppies
Run this coreboot.rom by executing this QEMU command: (some floppies are 64-bit)
qemu-system-x86_64 -L . -m 768 -localtime -vga vmware -net nic,model=rtl8139 \
-net user -soundhw ac97 -bios ./coreboot.rom -boot menu=on -serial stdio

Hi there Paul, Sorry for a late reply and thanks for your message, wish you a happy time and good health. > >> Add support for up to 35 boot menu entries (2 pages if >18).

With Gerd’s commit 18d237b4 (bootmenu: > add support for more than 9 entries), 34(?) entries are currently supported. > (No idea, why 0 is left out for example.) This " advanced_bootmenu.patch " has been already rebased in a coreboot change 32351 ( [1] ) and it still applies to a SeaBIOS master. This rebase was a bit lazy to be honest, but it still works thanks to boot.c not getting any significant changes for a long time since 18d237b4. Despite I love SeaBIOS so much, maybe because SeaBIOS isn't on Gerrit (or other reasons?) - it's so hard to get anything merged there, much harder than to coreboot or flashrom. I wonder why my "advanced_bootmenu" patch hasn't been even reviewed in its' original form despite multiple resubmissions. Although I was happy to see a Gerd's spinoff accepted in a commit 18d237b4 since it's better than nothing - however, it couldn't boot a large menu entry in a single letter keypress (only numbers are supported there), so I keep using my original version. Maybe I'll try sending the patches to SeaBIOS again when the optimistic mood comes... However, seeing that even a patch which fixes booting USB drives with a write protect switch enabled ( [2] ) has been rejected - despite it solves a real "broken hardware" problem - sadly it's more likely that a pile of "unofficial SeaBIOS patches" in change 32351 will keep growing. If you know any other good patches which also haven't been accepted to SeaBIOS, please let me know and I'll include them to 32351.
