How to upgrade BIOS? (Toshiba Sattelite/F16)

[basmoen]

Hello there!

While trying to resolve my problem on CPUscaling(in another thread), i thought that mabye a BIOS update
might help my problem.
But,everything stops here...

I've searched the Toshiba website,and only found something for Ubuntu,and a totally different laptop than mine.
I've altso searched here,and couldnt find anything :/

The Laptop:
Toshiba Sattelite C660D-11K (Only sold in Norway&Sweden)
Fedora 16 (custom kernel due to CPUscaling bug)

Every solution I could find,related to Windows-users,and thats no help for me :/

BIOS update guide i found for UBUNTU at the Toshiba site:

General BIOS udate guide for Windows users:
http://aps2.toshiba-tro.de/kb0/HTD9502M10000R01.htm

Files for this laptop at the Toshiba site:
http://nordic.computers.toshiba-euro...rvice=ND#tab3;

Is it possible to upgrade via USB og DVD/CD? Cannot find any information about this anywhere!
If so,what files do I have to put on the stick/disk?
I really hope someone can help me here.
Thanks in advace

The best way to do a BIOS update is on a windows installation, probably not linux.When it comes to BIOS, you need to have the right software for the right OS.

Your mileage may vary

Ok, so install the syslinux package. Very important.

Get from Dell, the biosdisk package. http://linux.dell.com/biosdisk/archive/

* The mkimage action will create a floppy image on the user's hard drive. Usage is the following:

biosdisk mkimage path/to/.exe

After creating the image, move it to /boot
copy memdisk from the syslinux package to /boot

for GRUB add AS AN EXAMPLE the following:

title E6500A22.img
root (hd0,0)
kernel /memdisk floppy c=8 s=32 h=64
initrd /E6500A22.img

for GRUB2 add AS AN EXAMPLE to /etc/grub.d/40_custom
(Make sure that the --set=root matches the other entries so the UUID is correct)

menuentry "BIOS E6500A27" {
set root='(hd0,msdos1)'
search --no-floppy --fs-uuid --set=root 08e757a9-bf74-4ed6-82f1-a017f83b3870
linux16 /memdisk
initrd16 /E6500A27.img
}

then run
grub2-mkconfig -o /boot/grub2/grub.cfg
