I had no trouble installing 2.6 on a regular Pentium 166Mhz unit with
a quantum fireball hard drive.  This PC (mine) has only PCI-IDE "ide
capabilities" - those on the motherboard. No problem.

Where did you read that? If that's what was really said then it's
wrong. Every motherboard I've seen that includes a PCI-IDE compliant
controller, has a BIOS which initializes the PCI-IDE controller
in ISA-legacy mode. If the PCI-IDE chip and the BIOS aren't buggy
it's pretty much impossible for an ISA-only ATA/ATAPI driver to
tell the difference between an honest-to-god ISA IDE/ATA controller
and a PCI-IDE controller in ISA-legacy mode. That kind of configuration
covers about 99.9% of the systems out there.

On the other hand, if your motherboard already has *both* a primary and
a secondary ISA IDE/ATA controller, and then you add-on a PCI-IDE
controller hoping to access it as a tertiary IDE/ATA controller it
isn't going to work because there's no standardized configuration
for a tertiary ISA IDE/ATA controller (and the 2.6 DCA ignores any
ISA IDE/ATA controllers at any non-standard addresses).

If you've got a motherboard with two ISA IDE/ATA controllers and you
want to replace either or both of them with a PCI-IDE controller, then
you just have to have a BIOS which allows you completely disable either
or both of the onboard ISA IDE/ATA controllers, and a PCI/IDE add-in
card with its own BIOS which correctly initializes the PCI-IDE chip
into ISA-lagacy mode (i.e., the PCI-IDE controller ends up at either
I/O: 0x1f0 and IRQ: 14, or I/O: 0x170 and IRQ: 15).

Well maybe you should take the opportunity to add some of your vast
knowledge to the FAQ then, I'm sure Dan wouldn't mind a little help from
someone as knowledgable as yourself.
</semi-sarcasm>

I've found the FAQ to be very helpful to me, and I think that most
people should read it before they post a message, many whom don't. I've
had my share of problems getting Solaris x86 setup also, just as others
have, but I don't think thats any reason to take a pot shot at Dan for
how you feel he is maintaining the FAQ. I think everyone is pretty darn
lucky, just that there is someone that is maintaining it.

I'm sorry if I offend you with this reply, but in all fairness, I have a
feeling that Dan would be pretty offended by reading your arrogant
message. I'm not trying to belittle you Bruce, I just wanted to point
out that the FAQ is maintained on a volunter basis, and if you think you
see an opportunity to add to it, by all means, help out rather than
taking a pot shot at the person who is currently voluntering their time.

Alan,

You must be new to x86 - Bruce has been giving good,
helpful advice for years (also on the x86 mailing
list).  Sarcastic remarks directed at helpful
individuals who know the internals of x86
aren't helpful to those of us who appreciate the
help Bruce has given.  I appreciate his posts to
this newsgroup and to the mailing list - he helped
me get x86 going on a notebook years ago and I'm
sure he has helped many others.

(I tried a private reply to you but you don't seem

Stuart

Stuart,

Yes, I am new to x86 and I've seen a lot of messages from Bruce helping
people. I don't have a problem with most of the messages I read, not by
Bruce, but by anyone. I happened to take offense at what Bruce commented
about the maintainer of the FAQ.

Quote:> I appreciate his posts to
>this newsgroup and to the mailing list - he helped
>me get x86 going on a notebook years ago and I'm
>sure he has helped many others.

And there are many other people that have helped many out. I just didn't
think it was a nice thing to comment on the NG, unless Bruce wants to
start maintaining the FAQ the way he feels it should be.

I'm probably a poor example to advocate "political correctness" as many
of my messages border on being in left field at times, but hey, I get my
opportunity to insert my 10 1/2 D into my mouth also! (and I've done it
many times). Maybe this will be one of those times I will had wished I
kept my fingers quiet, but it wasn't to be...;-)

>(I tried a private reply to you but you don't seem


I don't use my email on the NGs, gets too much SPAM in my mailbox. The
above account is not active anymore, IBM pulled it a few months ago. For
those that do know my email, they can contact me, and for those that do
not, can just post a message to the NG and I'm sure I'll read it.
