Did some more digging with google, and saw some more posts from his lordship
Bruce Adler (author
of ata.bef on Sol8x86), and from Phil Brown, author of a hpt 366 driver for
Sol x86..(my card has hpt370 chipset... very close).
Phil says his driver was not really for production use and needed ironing
out.
Have seen hpt370 support in Linux kernel code, which is very thorough with
code and comments from HighPoint wizards, and also got actual driver source
from Highpoint for Linux..
Have also seen Sun's sample Dev Driver source for a scsi controller...which
is supposed to be good starting point for Disk Controller Driver..
Think it would be nice if more solx86 users/coders started to produce dev
drivers for their own hardware to work and made it available freely... Thats
one of reasons IMHO, Linux really took offf... (apart from being free with
source code of course).
Think I'll have a look at the Open/Free BSD ata driver implementation (If I
can find it), before I make
decision to start coding, or locate a used beloved Adaptec 2940UW for use
with an old SCSI II UW drive I have hibernating under my bed.
