Re: Missing iBook HD driver?

[Robert E Brose II]

After corresponding with Ben H. on this and doing some testing
I reached the conclusion that:

If you have a dvd/cd-rw combo drive on a 600 mhz ibook the
stock 2.4 kernels will not recognise it. Ben has fixed this in
his kernel and I found an old reference in the faq-o-matic
(to an iMac) that you can work around it by specifying

hda=16383,16,63

as a kernel arg when booting from the install cd. I thought
I'd drop the info here so others can search it out when they
run into the same problem...

Subject: (fwd) Missing iBook HD driver?
Am I missing something? I'm trying to install on a 6 mo. old
iBook, 600 mhz, combo drive and 20 gig hd.

Neither debian 3.0, ydl 2.3 or gentoo 1.2 boot cd's find the
hard disk (though they all find the cd).

What's up with this??

I don't recommend the kernel arg thing. There is indeed
a workaround that seem to work properly in my current tree,
I'll try to get that merged upstream.

booting without any CD in that drive will also fix the problem.  that
of course means for initial install you need to boot via tftp or so,
unless your fast enough to remove the CD right after yaboot reads the
kernel, but before the kernel gets far enough to puke (that may not
work anyway).
