It is my turn to be grumpy I think:

1. All the stuff I am working with was "brand-new" (at least as far the
retailer is concerned) as of Sept. 1 and all is SATA/300

2. In an other subthread I mentioned I finally got PATA/SATA working
(i.e. co-existing) but the other 2 items on the wiki (plus the yet to be
recorded acd one) are still in existence

3. The PATA/SATA issue was only fixed by a couple of new definitions in
ata.c thus should not be considered anything more then a custom patch
for my machine I think

And that is why I volunteered to help out but it seems they prefer for
me to just send various diag dumps so neither of us has any grounds for
complaint here I think.

>From being around the industry since the late early 80's (I know you
have been around longer) I have come to the following conclusions:

1. Every 10 years or so there is a whole sell revolution in hw interfaces
2. The last one was Pentium, AGP, UDMA and PCI in the mid early 90's
3. The current one is PCI-E, 64bit, Multicore and SATA

Due to 3 I think if we get stuff right we are safe for a good 8 to 10 years.
