Hi,
When using EFI booting with GRUB on Ubuntu and Linux Mint I am able to include "outb" commands in my grub config file to write values to particular memory addresses. But on Fedora 18 this gives a command not known warning.
Can anyone suggest how to get outb working?
Thanks, Keith
$ yum provides \*bin/outb
Loaded plugins: langpacks, presto, refresh-packagekit
ioport-1.2-6.fc18.x86_64 : Access I/O ports
Repo : fedora
Matched from:
Filename : /usr/bin/outb
Is this what you're looking for?
Hi randomuser, not quite. I want to send commands to the multiplexer in my laptop to switch off the Radeon graphics card. I have vgaswitcheroo working but it's a bit flaky and I think using outb commands from grub will help.
