LSILOGIC also ship 3 drivers to cover the 53C810 - 53C1010 range on NT.
And, btw, these chips are all PCI.

Doing so, 12 different drivers would be needed to cover 4 different O/Ses,
for example. These drivers (I spoke about both LSILOGIC and ADAPTEC
drivers for NT) obviously work for i386, but what about architecture
dependencies at source level?

May-be this is the reason some UNIX vendors seem to love UDI. :)

If you also use SYMBIOS chips, you may give a try with SYM-2. For the
moment, it replaces only 6 drivers :) as also seems to do, for the moment,
Justin's AIC7XXX-6, by the way.

The plans seem clear to me. :-)
Btw, I _do_ like a lot better the 'one driver' plan over the '12 or more'
one.
