biosconfig Requirements
-
You must run
biosconfig
as root because it needs to use drivers that are in read- and write-protected physical address space. -
Close all other applications and quiesce your system before running
biosconfig
. -
Linux versions of
biosconfig
depend on access to/dev/nvram
to guarantee serialized access to the CMOS.Red Hat Enterprise Linux 4 distributions do not include the device by default. Red Hat Enterprise Linux 5 and SUSE Linux Enterprise Server distributions do include the device by default.
To use
/dev/nvram
, the driver needs to be compiled into the kernel (or loaded as a module), and/dev/nvram
must exist (root can create it usingmknod /dev/nvram c 10 144
).
