|
variables set by
|
|
.Xr loader 8 .
|

|
|
defauilts.

|
|
.Ic autoboot

as-is.
|
|
.It Fn core.boot argstr
|
|
Loads the kernel and specified modules, then invokes the
|

as-is.
|
|

|
|
.It Fn core.isSystem386
|
|
Returns true if this bootloader was compiled as an i386 binary.
|
|
This generally applies to i386 loaders as well as non-UEFI loaders on amd64.
|
|
.It Fn core.deepCopyTable tbl
|
|
Recursively deep copies
|
|
.Fa tbl
|
|
and returns the result.
|
|
.It Fn core.popFrontTable tbl
|
|
