I would also like to suggest PAN. It is starting to become very useful, at first
it was to buggy, but as of version 0.8.1 it is much better.
It is a GTK based application somewhat similar to Agent but from what I can
see a much nicer interface.

Marc,
Problem solved... Your hints did the trick. It
turns out to be a combination of two problems.
First, since I did the configure on the PentiumII machine,
it configured itself for a default of PPro instructions.
Secondly, the kernel make file has a bug in that while
it uses the standard CFLAGS arguments for all the kernel
modules itself, it does not use these same arguments when it
builds the kernel piggyback program, hence it only passed
-O2 to the compiler, leaving it default to PPro instructions
and hence on the misc.c module a program un-runable by
Pentium computers.
The problem could have also been prevented with a little
better configure documentation and prompting as its not
really clear that it will choose a PPro instruction set
by default bases on the installed computer.
In fact the docs discourage overriding the
default target and don't document what valid options are.
In my case, I actually did the configure on the Pentium
to ensure it picked Pentium as default
Anyway, I'm not looking to assess blame, but rather
posting this message to say thanks and hopefully provide
a clue to other people who might stumble into this in the
future; hence I'm .cc the news groups and pgcc group
to get it into the archives.
Thanks again.
Brian

Try to run etc/config.sub.. if it outputs something with i686 then gcc
and
pgcc will use ppro-instructions for the runtime libraries (and
everything
else) by default.

Yes, just configure it as "i586-something" instead of as
"i686-something".
gcc -v displays the current configuration:
cerebro:~# gcc -v
Reading specs from /usr/lib/gcc-lib/i586-pc-linux-gnu/pgcc-2.95.2/specs
gcc version pgcc-2.95.2 19991024 (release)

Indeed, the pgcc version makes a lot of use of the conditional move
instructions:
+ cmovae %eax,%ecx
However, since you said you call it with -march=pentium this should not
really happen. Strange. Are you sure the switches reach the compiler?
Anyway, configuring pgcc with pentium as default target will solve that
problem.

2.2.16 But as I said it is a custom built kernel, stripped down to only
what my system needs. After being compiled there is a lot of the code
that can be removed from the system. About the only thing left on my
system is .h files for the kernel.
You do know about the bug in all kernels prior to 2.2.16 don't you?

You only need execute on the user's home directory (chmod o+x).

Make all users home directories owned by the user and group "users".
Put all users in "users". Take away rwx for "users" on the home
directories, but leave execute for "other".

Which edition of the book? It's currently in its 3rd edition as I
recall. There is sufficient change and variance among distributions
that discrepencies may be apparent.

Use what works. "nrst" means "no-rewind scsi tape", "nst" abbreviates
the "r" out of that. Not sure if/when that changed. If you do note
changes, check out the feedback section of the book and submit your
remarks to the author or editor as appropriate.
For documentation, refer to books for context, system documentation for
your system specifics, and actual behavior for how things work. Usually
commands have a -help or --help option which will show switches. In the
case of device files, you might want to look under the kernel sources
(/usr/src/linux) for some information as to what's significant (hint:
mode numbers, not names).

My $0.02, using the *1st* edition, is that it is useful in terms of
describing general philosophy and tactics of Linux. Most of the specific
installation and configuration details have changed significantly.
Sections dealing with X configuration are almost completely historical.
The rest of the book becomes an overview of general system capabilities.
I refer to this book less often than I do references for specific tasks
(networking, programming languages). I also have Nemeth and Frisch's Unix
system administration texts handy, as well as Kernighan and Pike's _The
UNIX Programming Environment_, which, though *very* dated (early 1980s),
is also quite useful in desribing what the fundamental Unix philosophy
is all about.

Yes. The odd thing is the other things I can do. I just made a boot disk, dd
if=boot.img of=/dev/fd0, which I used to upgrade to RH6.2. However, this
didn't help, attempting to mount either the floppy or the cdrom still hangs. I
guess it must be something with the kernel, considering the RH boot.img was
able to mount the cdrom. I would think a prepackaged kernel wouldn't give
difficulties like this. Or perhaps some library mount uses got corrupted, but
then it mounts /dev/hd[ab] fine on bootup. The hardware certainly works.
Still not knowing what action to take,

According to the LILO documentation, error 0x10 means "CRC Error". This
often means that LILO has been installed to a spot on the disk which
contains bad sectors. The documentation suggests trying to boot again,
booting from a floppy disk and re-running LILO, re-installing Linux,
this time using the "Format and Check" option when it comes time to
format/partition the disk, and as a last resort replacing the hard
drive.
Someone else reported this same problem not too long ago. It might help
to know the motherboard and hard drive makes/models so we can determine
if there are problems with a specific type of drive or chipset....

The G400, though, should work fine. Just lie and tell the kernel you
have a G200. (The two are similar enough that for most things the G400
appears as a fast G200 with some added capabilites.)

As >spamless< suggested, mount has a -v (verbose) mode, so what happens
if you try this:
mount -v -t iso9660 /dev/cdrom /mnt/cdrom
and then (when it won't work)
do this:
tail -f /var/log/messages
which will let you see the last 10 or so messages in your log. I just
tried this and my mount command is working, so /var/log/messages had
three lines telling me hdb had just been mounted with an ISO9660
filesystem. Yours possibly will have something saying what went wrong.
Then maybe we can come up with a solution!
Hope this helps,

This would most likely be prohibitively expensive in terms of CPU
time... the root partition is accessed dozens of times per second, if
only for libc. If you could tell us what you need this for, it's
possible that we could tell you of a tool that would do what you want.

syslogd writes to the disk every so often, and update syncs the disks
every 30 seconds by default. You can change this behavior by editing
/etc/inittab (/sbin/init.d/boot on SuSE systems) and changing the line
that says "/sbin/update" to "/sbin/update -s NUM -f NUM" where NUM is
a time value in seconds. Also, read the man page for hdparm to find the
command to sping the drive down after N seconds of inactivity.

1. Why? Is this a laptop? If not, probably not. If so, it's very
dependent on actual hardware. If you just want to blank the screen and
have the drives spin down, see above for "update" tweaking, and mess
with hdparm and the X-Server's DPMS options. (Better yet, turn off the
monitor when you're going to be away from it for a while.)
2. Dependent on actual hardware. Wake-On-LAN Ethernet cards are
available, and Wake-On-Modem capability may be present in your
motherboard BIOS.
Keep in mind that modern hard drives are built/made to operate
continuously. I've had mine running for a month at a time without
problems, and these are cheap-arse IDE drives. If it's noise you object
to, get a heavier case or put sound-insulating material around the case
you have.
