I released a new version of the /dev/bios flashrom drivers some
minutes ago. With these you are able to read/write any System
BIOS flash chip (Well, errm. You ought to do that. It may not work
on your computer, though)
New features in this version are:
* thousands of bugfixes :-)
* you need to insmod bios.o write=1 to allow writing (sysctl support
will follow)
* PCI chipset probing to detect which shadow/deshadow routines to use.
Well, this may cause problems with 2.1.93 PCI code. I've only tested
it with 2.1.90
* some few ioctls implemented to switch on/off shadowing and reprobe
flash chips
* Lots of other stuff
I've tested /dev/bios successfully on some Intel 430*X chipset boards as
well as on two
486 PCI mainboards using the UMC 8881 chipset.
The only flash chips that is securely supported is the winbond 29ee011.
This does not
mean flashing is not dangerous on that chip, but that chip had most
testing right now.
Please test this careful and report anything. I am in no way responsible
what happens to
your hardware (Though I'll try to help you if anything gets burned
because of /dev/bios)
