I have a hard drive which has 2 ntfs partitions (c,d) one Fat32 (e) and
then Linux (hda7). I would like to enlarge e and make the linux partition
smaller using partition magic 6. Will I be able to boot after this?

The 2.2.x series should have 2k block size support without patches.

BZZT! the throttling method is very much available using APM, and the HLT
instruction is available in almost all pre-compiled kernels I've ever come
across and I put it in every kernel I compile myself.

well, only if it's necessary. the larger fan is likely to use more power
itself (though heatsinks do seem to be getting more efficient rather than
larger so perhaps the same is true for fans...)

not really as daft as it sounds, think about it, if I run vmstat it'll tell
you something...
sammy@osyd:~$ vmstat
procs memory swap io system
cpu
r b w swpd free buff cache si so bi bo in cs us sy id
0 0 0 49096 2444 5576 20568 1 0 3 3 6 6 7 3 10
sammy@osyd:~$
ten percent of the time my cpu is doing _nothing_ (or rather running the hlt
instruction) and that's while running setiathome (I guess it has to wait for
network access which it usually only gets for an hour a day) so on average
my CPU runs at 90% of its maximum available speed. Over time this means that
I only need 81% as much cooling (heat produced is proportional to the square
of the cpu speed, approximately) and that's with background processes using
the cpu nearly all the time, on my laptop (before it died!) I got 99% idle
time even while I was using it! that means that my cooling requirements
would've been drastically reduced if the cpu'd understood hlt (didn't,
crappy 386 ;) so much so that the cpu would've been totally insignificant in
energy requirement! so whatever the exact figure, you'll need less cooling
and can put your max speed up higher for the same cooling, providing you
don't use it at max speed for a long time (throttling can handle this w/o
problems if you have temperature sensors etc.) and you get almost _all_ the
advantages of the fast cpu, given that (almost) all the time the cpu does
anything, it does so at top speed.
err, that might've been more effluent than eloquent, but hey :)
Cheers & God bless

grep -i idle/usr/src/linux/.config
if you compiled your kernel yourself, or otherwise less /var/log/dmesg (or
just dmesg) will show you the bootup sequence (unless, like me, you have had
your computer running a long time since then, the program dmesg only shows
you the last bit, the file seems to contain only the first bit, oh well :)
anyway, you're looking for a line like the following:
Checking 'hlt' instruction... OK.
which indicates that your kernel successfully found and has activated use of
the hlt instruction.

I think he means the multitude of background processes that run on a typical
linux box, telnetd, inetd, apache (on a surprisingly large number of boxen
when it's really not needed on most!) and a squillion other little daemons.
OTOH, even between them they tend to spend most of their time waiting for
something to do and v. little of it actually doing anything :) for example:
sammy@osyd:~$ ps waux | grep -v sammy | wc -l
34
sammy@osyd:~$
and that doesn't include things like xscreensaver which fall v. much into
the category of daemon behaviour, though I run them as my normal user.
Cheers & God bless

it'll complain bitterly, but if you read the manpage I believe there's an
option to make it tollerant of missing files, it'll just produce a bunch of
*.rej files containing the bits of patch you haven't got, then you can do
something like find /usr/src/linux/ -name *.rej | xargs rm -f

Then you should have given the group write permission.

Now *that* makes sense [is normal]. Use 'mount' with umask=007, along with
uid=1234 and gid=123, for example.

umask accepts the complement of the desired permission, so for 777 you
enter umask=000

You probably messed up things so they're now worse.

isn't supposed to work! chmod 777 /hda ! /hda refers to complete disk, /hda1
refers to partition 1 on that disk.

Now THAT was stupid :)
I knew the default permission field was the umask command and forgot about
the subtraction thingie :)
It's a stupid field name though!Couldn't it say <umask>?Default permission
makes you think..what permissions do i want?Let's enter the value..
Either way it worked.
Thanks again Eric (for the 10th time or something) :)
I was wondering..since the default permission is 666, is there a way to
make it 777 through umask? -111 didn't work of course but i thought that
-(-111) equals to +111 :)

Date: Fri, 18 May 2001 08:54:48 -0700
Reply-To: [EMAIL PROTECTED]
Hi, I have a piece of fortran 77 code which compiles find on various
unix machines
that I have access to, Suns, SGI machines etc. I attempted to compile
the code on my linux box, redhat 7.0 with gcc 2.9.6 (I assume it calls
f2c),
I also tried f2c directly. It seems to have some problems understanding
some logical operators. Here it a snip of the error message:
movcol.f: In subroutine `movcl1':
movcol.f:633:
if (phypde.eq..false.) y(m*i) = rwk1(m21+1)
1 2 3
Use .EQV./.NEQV. instead of .EQ./.NE. at (2) for LOGICAL operands at (1)
and (3)
movcol.f:642:

1 2 3
Use .EQV./.NEQV. instead of .EQ./.NE. at (2) for LOGICAL operands at (1)

if (phypde.eq..true.) then
1 2 3
Use .EQV./.NEQV. instead of .EQ./.NE. at (2) for LOGICAL operands at (1)
and (3)
There are several more lines of this corresponding to each encounter of
such
logical tests.... is there any compile time option which will allow this
to compile
without having to change the code. This is not my code so even a
marginal rewrite
would cause problems besides the obvious portability issues.
Any help would be greatly appreciated. If you could reply to my email
as well
as the group that would be great.
Thanks,
R Haynes

Don't know, but there's a program called symlinks on the 2.2 CDs which can
