Re: IDE?

OSDL does not support IDE.

See, I asked some time ago about testing raid arrays and a possible thread
driver. All you will find there is onboard hosts, and I do not believe
they stock the all the junk systems out there.

150 systems is a not a large enough sample.

500 ++ w/ various add-in cards * (the number of drive models per vendor) *
the number vendors eek stop ....

Add in ATAPI devices, CFA, etc ...

You see the combination are of a scale unchecked.

I started at one point trying to have a single drive vendor with at least
1000 or more systems in one lab to test their product over the host
hardware base, to run kernel checks. The task was beyond scale.

All it takes is a bus analyzer and a few systems known to be good to
perfect the driver. Then you deal with all the exceptions of the crap
combinations.

That is how I do it, since I have a code base that has been run over a
bus analyzer I know it works.

Cheers,
