SMBIOS-TYPE-11(7) smbios-type-11 SMBIOS-TYPE-11(7)

.SH "NAME" smbios-type-11 - SMBIOS Type 11 strings

.SH "SYNOPSIS"

.PP /sys/firmware/dmi/entries/11-\*/raw

.SH "DESCRIPTION"

.PP Various OS components process SMBIOS Type 11 vendor strings that a virtual machine manager (VMM) may set and a virtual machine (VM) receives. SMBIOS Type 11 vendor strings may play a similar role as [**kernel-command-line**(7)](/man/os/systemd/kernel-command-line.7) parameters but generally are under control of the VMM rather than the boot loader or UKI.

.PP For details on SMBIOS Type 11 see the **System Management BIOS**\[1] specifications.

.SH "STRINGS"

.PP The following strings are supported:

.PP *io.systemd.credential:CREDENTIAL=VALUE*, *io.systemd.credential.binary:CREDENTIAL=VALUE*

This allows passing additional system credentials into the system, in textual or binary (Base64) form. See [**systemd.exec**(5)](/man/os/systemd/systemd.exec.5) and **System and Service Credentials**\[2] for details.

Added in version 252.

.RE

.PP *io.systemd.stub.kernel-cmdline-extra=CMDLINE*

This allows configuration of additional kernel command line options, and is read by the kernel UEFI stub. For details see [**systemd-stub**(7)](/man/os/systemd/systemd-stub.7).

Added in version 254.

.RE

.PP *io.systemd.boot.kernel-cmdline-extra=CMDLINE*

This allows configuration of additional kernel command line options for Boot Loader Specification Type 1 entries, and is read by **systemd-boot**. For details see [**systemd-boot**(7)](/man/os/systemd/systemd-boot.7).

Added in version 256.

.RE

.PP *io.systemd.boot-entries.extra:ID=DEFINITION*

This allows inserting additional entries into the **systemd-boot** menu. For details see [**systemd-boot**(7)](/man/os/systemd/systemd-boot.7).

Added in version 258.

.RE

.PP *io.systemd.boot.loglevel=LEVEL*

This allows configuration of the log level, and is read by **systemd-boot** and **systemd-stub**. For details see [**systemd-boot**(7)](/man/os/systemd/systemd-boot.7) and [**systemd-stub**(7)](/man/os/systemd/systemd-stub.7).

Added in version 259.

.RE

.PP *io.systemd.boot.timeout=TIMEOUT*

This allows configuration of the menu timeout in seconds, and is read by **systemd-boot**. For details see [**systemd-boot**(7)](/man/os/systemd/systemd-boot.7).

Added in version 260.
