help
Stable SeaBIOS version

bool "master"

Newest SeaBIOS version
config SEABIOS_REVISION
bool "git revision"
help
Select this option if you have a specific commit or branch
that you want to use as the revision from which to
build SeaBIOS.
You will be able to specify the name of a branch or a commit id
later.
endchoice
config SEABIOS_REVISION_ID
string "Insert a commit's SHA-1 or a branch name"
depends on SEABIOS_REVISION
default "origin/master"
help
The commit's SHA-1 or branch name of the revision to use.
config SEABIOS_PS2_TIMEOUT
prompt "PS/2 keyboard controller initialization timeout (milliseconds)"
default 0
int
help
Some PS/2 keyboard controllers don't respond to commands immediately
after powering on. This specifies how long SeaBIOS will wait for the
keyboard controller to become ready before giving up.
config SEABIOS_THREAD_OPTIONROMS
prompt "Hardware init during option ROM execution"
default n
bool
help
Allow hardware init to run in parallel with optionrom execution.
This can reduce boot time, but can cause some timing
variations during option ROM code execution. It is not
known if all option ROMs will behave properly with this option.
config SEABIOS_VGA_COREBOOT
prompt "Include generated option rom that implements legacy VGA BIOS compatibility"
default y if !VENDOR_EMULATION
depends on !(VGA_BIOS || VGA_ROM_RUN) && (VGA_TEXT_FRAMEBUFFER || LINEAR_FRAMEBUFFER)
bool
help
coreboot can initialize the GPU of some mainboards.
After initializing the GPU, the information about it can be passed to the payload.
Provide an option rom that implements this legacy VGA BIOS compatibility requirement.
config PAYLOAD_CONFIGFILE
string "SeaBIOS config file"
default ""
help
This option allows a platform to set Kconfig options for a basic
SeaBIOS payload. In general, if the option is used, the default
would be "$(top)/src/mainboard/$(MAINBOARDDIR)/config_seabios"
config SEABIOS_BOOTORDER_FILE
string "SeaBIOS bootorder file"
default ""
help
Add a SeaBIOS bootorder file. From the wiki:
"The bootorder file may be used to configure the boot up order. The file
should be ASCII text and contain one line per boot method. The description
of each boot method follows an Open Firmware device path format. SeaBIOS
will attempt to boot from each item in the file - first line of the file
first."
See: https://www.coreboot.org/SeaBIOS#Configuring_boot_order
If used, a typical value would be:
$(top)/src/mainboard/$(MAINBOARDDIR)/bootorder
config SEABIOS_ADD_SERCON_PORT_FILE

help
Select this option to enable SeaBIOS' VGA adapter emulation
on serial port.

depends on SEABIOS_ADD_SERCON_PORT_FILE
default TTYS0_BASE
help
Set this field to the IO address of a serial port for SeaBIOS' VGA
adapter emulation.
By default primary console UART defined by TTYS0_BASE is used.

help
The higher the number, the more verbose SeaBIOS will be. See the table
below for the current values corresponding to various items as of SeaBIOS
version 1.10.1. Set this value to -1 to use SeaBIOS' default.
Output at various SeaBIOS log levels:
level 0 - Logging disabled
level 1 - Basic output, interrupts 5, 18h, 19h, 40h, SMP, PNP, PMM
level 2 - AHCI, Floppy, Basic ps2, interrupts 11h, 12h, 14h, 17h
level 3 - bootsplash, initializations, SeaBIOS VGA BIOS interrupts
level 4 - bios tables, more optionrom
level 5 - Extra bootsplash, more XHCI
level 6 - ATA commands, extra optionrom
level 7 - extra ps2 commands, more OHCI & EHCI
level 8 - extra malloc info, more AHCI
level 9 - interrupts 15h, 16h, 1ah, APM, PCI, SMIs, PCIBIOS,
USB-HID commands, SDcard commands, Floppy commands
level 10 - interrupt 13h (Drives other than floppy)
level 20 - interrupt 10h (Display)
