interesting to see the inclusion of the "promise pdc20270"
this is the same chipset off the original "fasttrack" ide raid pci cards
which i was writing about suspecting them as the origin of the
"mac bootable" seritek firmware after reading the hex code inside the firmware file

Yes, it is Interesting...

Mactron... I am so interested in the results of this thread. 

Yes, me too... LOL

Those are just "preliminary studies" ...
An "active member" of the forum  kindly offered me a machine to test ...

So, we will see ...

I'm waiting to do the real test ...
