Has anyone tried upgrading the BIOS on Dell laptops?
This is the Dell Windows based update for my Studio 1558 laptop. http://dell.to/fp5qcj
Would this work using Wine? Is there a Fedora way to apply this update?
It won't work in Wine. Use Unetbootin to make a bootable USB stick and flash from that.
yum -y install unetbootin
Then use the FreeDOS option when making the boot stick and you'll be set. Once you've made the boot stick you can copy the flash .exe file over and give it a go.
