Hi guys,

I currently use the /dev/bios work for flashing BIOS in a production
evironment on a GX1+5530A platform. It works great.  It may not work out of
the box for SC2200/SC1200 (I have no experience on these platforms), but it
would be well worth getting it working - it supports a large number of
different flash parts and provides a great interface.  Sounds like Adam has
already done the hard bit!

One issue might be that most SCx2xx-platforms probably wire up the flash CE
and WE differently, and they need to be enabled before any writing to the
flash will work.  Register hunt, anyone?

OTOH, if you're working on flashing LinuxBIOS on a platform you might
already have access to the neccessary documentation, it's needed for
tweaking the configuration as well.

devbios works fine for me too and I've tried it on one SC2200 board
and a lot of GX1+CS5530 boards.  I've had to add definitions for a few
new chip ID's every now but that's all.
