Subject: [PATCH 1/1] Add runtime option: etc/only-load-option-roms (load, but
|
|
||||||
don't run)
|
|
||||||
|
|
||||||
From anecdotal reports, sometimes it is useful; I've heard of instances where
|
|
||||||
certain Nvidia graphics cards can, if using the nouveau driver on a GNU+Linux
|
|
||||||
system, be used without running any option ROM, but where the option ROM has
|
|
||||||
certain data tables in it that the driver can use.
|
|
||||||
|
|
||||||
If set to 1, this will disable *all* option ROM loading, even SeaVGABIOS. It
|
|
||||||
also affects CSM. In practise, the only time someone would ever use this is if
|
|
||||||
they were using a graphics card in the above scenario. Such a use-case is
|
|
||||||
incredibly rare.
|
|
||||||
|
|
||||||
If set to 0, the normal behaviour can be observed (load, and execute). The
|
|
||||||
run time option etc/pci-optionrom-exec will still be in effect.
