An X server would be a pretty decent candidate, although rumor has it
that XFree86 is a real bear to get compiled, which might make the
exercise sufficiently daunting as to be impractical.
Libraries (libc, compression libs, ...) would be the "second best"
candidates.
If you're using RAID, there are some particular MMX optimizations that
may be of benefit, but there does not otherwise appear to be
*substantial* benefit available from recompiling.
Do you have a particular application that doesn't run fast enough, and
you've exhausted the improvements that come from low-effort options
such as:
- Adding RAM
- Upgrading CPU?
If so, then you should already have a good feel for the precise
bottlenecks that need to be dealt with.
The *right* approach is to benchmark the application that runs too
slowly, and relieve the bottleneck associated with that application.
If you *don't* have a good feel as to what bottlenecks need to be dealt
with, then flailing away by fiddling with compiler options may feel
good, but is highly likely to be wasted effort.

Date: Wed, 02 Jun 1999 15:48:39 -0700
Hello everybody!
As far as I know, a Linux version for the Palm Pilot and even one for
the Atari Portofolio has been already developed. Did anybody start to
develop a 'Pocket Linux' for Palm-size PCs? (I mean this devices running
now WinCE)
If not, I would like to know if there is a way to synchronize
(appointments and to-do list would be enough ;) such a device with a
Unix-box.
Thanx,
Christian

Subject: dmesg: Unknown PCI device
Date: Mon, 07 Jun 1999 22:04:53 GMT
Hello,
I have a cheap 56K modem I picked up at Best Buy for $19. It's a PCI
PnP modem, works beautifully under Win95. I'm using TurboLinux 2.0
(based on RedHat), kernel version 2.0.33. Upon bootup, I get "Unknown
PCI device found", and dmesg confirms it. I did recompile the kernel to
exclude stuff I don't use and put other stuff into modules. Is it
possible that the kernel does support it, but things are broken because
of recompilation? (I just want to make sure, but I don't think so
myself). I'm thinking of upgrading to the latest Linux. Does the newer
kernel still have problems with the PnP PCI devices?
Another question: I boot Linux through loadlin, but when I cold- or
warm-reboot (reboot=warm kernel param), Win95 will always lock up on
startup. Apparently it fails on loading esdi_5x6.pdr driver. Is there
anything I can do to solve this problem, or has it been solved with
newer kernels?
Thanks in advance.

Reply-To: Flash <[EMAIL PROTECTED]>
Hey,
Just got a nice 19" Viewsonic G790 Monitor. I need to upgrade the video card
to take full advantage of the higher-res modes, but for the time being, I am
running in 1024x768 on the S3 server, 16bpp.
My question is, since the monitor is not listed in the XFree86Setup, is there
a monitor I could choose which would match the settings of my own monitor
to very closely.
Thanks for any help.

Doesn't the 'i' in ibcs stand for 'Intel', as in x86? A Sparc CPU is
NOT an x86 family member. I'm guessing that ibcs is an x86 only thing.

(Please pardon if this is posted twice, deja.com is new to me)
I had similar problems, my /var/log/messages file showed these errors
when accessing the offending directory:
isofs_read_level3_size: More than 100 file sections ?!?, aborting...
So I patched fs/isofs/inode.c in two places (search for More) to use
10000 instead of 100 as the limit on retries. It seems at least some
CD-R's have many more file sections than the isofs author anticipated.
Can anyone confirm this is the correct solution?

Hi Will,
Staroffice, Nescape and KDE or 3 programs that use a lot of mem. Take
some time to try out other WM's like Window Maker (
http://www.windowmaker.org ), blackbox or icewm. They use a lot less
memory and things might get smoother. Further more it also counts what
deamons you are using...
Open a console and type:
top
This will give you an overview of what processes are running and the
amount of mem they are using.

Date: Mon, 07 Jun 1999 23:48:38 GMT
I've got a real problem. I followed the instructions for driving an
ATAPI CDR by configuring my kernel for scsi emulation. All works fine
for the CDR, but now I can't access my scsi harddrive. A listing of
/proc/scsi/scsi shows the two cdroms but no harddrive. If I boot the
kernel without scsi emulation, the harddrive shows up fine. Can I have
both?
Thanks.

Linux can easily remove NT without any problems. During the install you
can remove the NT slice (partition) and make new Linux partitions right
over where NT was.

A WINModem is a really bad idea in any system. Normal modems have a DSP
which actually run the modulator algorithm (which is now in software).
WINModems attempt to be cheaper by running this code on the host
processor.
As you can guess, the host processor was not designed to do that sort of
thing nor is it a good thing to take such CPU power away from what you
really have to do.
Honestly, I only buy external modems anyhow (since I have a lot of Sun's
and HP's that won't take internal modems)... External modems are nicer in
many respects.
> I had heard in the past that this may cause difficulties under Linux, is

Yes. I don't doubt that somebody will write the appropriate kernel driver
to make them work one day; but I do doubt why anybody would want one.
Bottom line: Main CPU != DSP.

It was a while ago, but I had a chance to compare gcc 2.5.8 (I think)
against Borland 3.0. gcc blew away Borland so bad it wasn't funny.
Took me a week to come up with the (assembler) code that gcc spat out
by just typing -O.
