Interrupt settings on SCSI can change on kernel.
Would you rebuild your kernel for you?

Would you use the Gary's zImage-2.2.10-ide image?
That stays on ftp://ftp.linuxppc.org/user/gdt/ .
And you would like to stay Linux with NT?
That sounds difficult on 850.
You would boot up Linux from FDD (or CD-ROM) ?
When boot from FDD, boot up Linux, and automatic boot up NT
without FDD. That maybe selects booting.

When boot up kernel, options for tty output makes signs out
for serial console. To stop this, delete before booting by
backspace.
I didn't use debian/prep (I am waiting for the CD-ROM image.).
So I don't know about it, but if the installer of debian use
some other screen format, like framebuffer?

No. There are at least 4 of us in this situation now. I left an
extensive email trail on -user and then on -workstation; probably only
the end would interest you.

I'd love a working kernel - do you have a URL for that 2.0.32?
Of course, ramdisk format seems to have changed. The last time I tried
an older kernel it choked trying to read in the LinuxPPC 1999 ramdisk
(that I'd used fine with 2.2 zImages).

I had the most success by disconnecting the CDROM altogether.
After doing this, I could pass the partition check and all with no
problems. However, any disk activity (like mke2fs or rpm installation)
would result in many many "hda - lost interrupt" messages. Data would
eventually get written, but it was very very slow and unhappy. I believe
the kernel image I have at
http://www.andrew.cmu.edu/user/hollis/zImage-2.2.10 exhibits these
symptoms (it does have working builtin ethernet though. Yay.).
The conclusion we drew before was that something broke the IDE driver on
PReP machines. A Motorola PowerStack I with IDE was exhibiting the same
behavior I believe. That machine was shipped to the person who knows the
most about this problem, Gary Thomas, who's extremely busy.

I may be receiving a SCSI card to try with (since the problem is
supposed to be in the IDE driver... but now that seems less likely?).
I'd be ecstatic to get these machines working again.
The basic image that's supposed to work (and does on SCSI PowerStacks at
least) is located at ftp.linuxppc.org/users/gdt. I think the one you
want is zImage-2.2.10.install. Install instructions can be found at
http://www.linuxppc.com/think/r5-prep-install.shtml. Any problems you
have with that kernel and instructions should be posted on -workstation
so we can try to work through it I think.
