Custom Splash Screen

[Ahamed Husni]

Hi all,

I want to display a custom logo in the splash screen for a specified amount
of time (SeaBIOS as payload). How do I configure the logo and give a
timeout when building coreboot? Any pointers will be really helpful.

Regards,
Husni.

Logo: https://www.seabios.org/Runtime_config#Bootsplash_images

You may add the custom logo to the CBFS by specifying the path to logo 
file during coreboot build in menuconfig General Setup -> Add a 
bootsplash image
SeaBIOS is quite picky regarding the format of the JPEG and BMP. Be sure 
to use some legacy screen resolution, the logo file must also exactly 
match the screen resolution.
Here is a blog from Purism where some struggles with JPEG format and 
SeaBIOS are discussed: 
https://puri.sm/posts/librem-13-coreboot-report-february-25th-2017/

Specified amount of time: 
https://www.seabios.org/Runtime_config#Other_Configuration_items 
(etc/boot-menu-wait)

The timeout can be added using cbfstool after the build is finished:

cbfstool coreboot.rom add-int -r COREBOOT -n etc/boot-menu-wait -i 
<timeout_value>

If you have vboot with multiple CBFSes then you would also need to run:

cbfstool coreboot.rom add-int -r FW_MAIN_A -n etc/boot-menu-wait -i 
<timeout_value>
cbfstool coreboot.rom add-int -r FW_MAIN_B -n etc/boot-menu-wait -i 
<timeout_value>

Hi Michał Żygowski,

Thank you for the quick response. The links you provided
have important information which I could not have figured
myself out. I will try it and let you know the results :)

Thank you,
Husni.

Yeah the Purism post is written by the great Youness Alaoui who worked
pretty hard to get the LibreM BIOS working. I remember the time where he
was posting regularly on the coreboot list here. Amazing work and
documentation. I for one am thankful for Purism hiring him.
