I installed Mklinux DR3 on my Powermac 6100. When I installed
it I had my extenal zip disk installed. Now if I try to boot
Mklinux without the power to the zip drive (or without the
zip drive plugged in) I get lots of complaints, it won't mount
the various file systems and won't boot. What have I done wrong?

The SCSI ID of your internal drive is higher than the SCSI ID of your
Zip drive. The 6100 has just one SCSI bus for both the internal and
external devices. When you installed DR3, this caused your Zip drive to
get the designation "/dev/sda", and your internal drive got the
designation "/dev/sdb". When the Zip drive is turned off, your internal
drive gets the designation "/dev/sda". Since MkLinux is looking for all
your files on /dev/sdbX partitions, it gets confused.
Here's what I would do:
- boot into MkLinux with the Zip drive turned on.
- adjust the file "/etc/fstab" so that all references to /dev/sdb are
changed to /dev/sda
- shutdown
- turn off the Zip drive
- boot into MacOS, change your lilo.conf's rootdev (by pressing "custom"
from the MkLinux Control Panel) so that it points to /dev/sdaX instead
of /dev/sdbX (where X is a partition number)
- boot into MkLinux, your file-systems should mount okay.
If that works, then you need to adjust your SCSI IDs so that the Zip's
ID is higher than the internal drive's SCSI ID. You may be able to get
away with simply setting the Zip to ID #6, or you may have to open up
your machine and remove the correct jumpers from the SCSI drive so that
it gets a lower SCSI ID. (It's usually preferable to have your internal
drive be SCSI ID #0.)
When you're in MkLinux, you can do this to see what's what on your
SCSI bus:
cat /proc/scsi/scsi

Yes! That was it. Thanks for the reply.

1. More newbie MkLinux questions ...
Greetings ...
OK, I finally figured out how to display the time / date, as well as set
the time / date on MkLinux (date +%c to display, date -s"time and date
string" to set). I'm an NT developer by trade, so a lot of this setup
stuff is very new to me, but i'm diggin' it, I can see how powerful
Linux can be, in part 'cuz the granularity of things you can do is
smaller (I don't recall having the option of recompiling the NT kernel
<g>) ...
However, i've still got questions:
1. locate / find -- can I have MkLinux automagically update this file
database, so locate / find _always_ work? I find it distressing that I
can find no functional equiv. to the old DOS "dir /s "funky file to look
for"" command. I mean, ls -R|grep "funky file to look for" does it,
but, like grep on NT, it only shows you the line, the directory it was
found in was on a different line. If I run updatedb, sometimes it works
and sometimes not (i.e. sometimes I can find new files I added after
running updatedb, sometimes not). What am I doing wrong?
2. Environment -- is there a TCL / TK / Perl / something script that
runs when you log in? I'd like to put set commands in there i.e. set
MOZILLA_HOME /opt/netscape. How do I do this? What is the name of the
script? What is it's secret? Who does it serve?
3. X settings -- AfterStep looks nowhere near as cool on my MkLinux DR3
7100/66 as it does on my uncles' 486/66. How do I set up color /
background / etc. prefs using FVWM? KDE does it via the GUI but wow, is
it s-l-o-w. FVWM is _so_ much faster.
4. Mach / server pair -- is there a later release of the Mach kernel /
Linux server pair? One I can easily install without recompiling
anything (i'm used to compiling C/C++ code at work on NT, but not on
MkLinux, and I figure i've got lots to learn before i'm comfy with that).
5. G3 upgrades -- I read on www.mklinux.org recently, something about G3
upgrade card support in the kernel / server / something. I've another
Mac (6100/60) that I put a Sonnet G3 card in. It rocks ... I use the
6100 for music production, the idea is to not use it for anything else
i.e. use the 7100/66 Mklinux box to do everything not music related
(internet, email, etc.) I'd like to get a Sonnet / Newer card for the
7100 as well eventually, and if I don't need to muck with extension
typing (i.e. if MkLinux supports G3 upgrade cards itself without the
need for the MacOS extension) that would rock ...
I _do_ appreciate all the help here ... I really do!
