I think this was the original point I tried to make at the start
of this thread. Mips chips (r10k's et al.) are capable of doing far
more work per clock cycle than Intel chips. At least with my code,
which I mentioned previously was astrophysical fluid dynamics
with a SPH (smoothed particle) code and with another (grid based)
PPM code.
By the way, sorry to all for starting a religious war.
I didn't mean to.

Hey Peter, you helped me in spite of yourself :) THANKS :)
For anyone else out there besides Peter, how can I handle this problem
of the chmod failing (quite rightly, I understand now). For instance,
with "gmc" file mgr, it refuses to copy the file because of the chmod
issue, which (understandably) fails. If I "cp" it in a shell, it works
fine despite the error. Just ignore it?? Thanks.

Subject: Booting troubles, MBR not right?
Date: 6 Sep 2000 21:55:35 GMT
At boot time I end up with a cursor on an
otherwise empty screen. No "LILO" or subset
thereof.
With a boot floppy, everything is fine.
/boot has its own 19 Mb partition, /dev/hda1.
LILO has been used to install to both the
MBR and the partition table. (No luck
either way) Linear is turned on.
The BIOS is set to look at the hard disk
after any removable devices (though strangely,
the disk where Linux is installed is listed
twice, there is also a SCSI data disk
not visible from BIOS)
This was not a problem until I upgraded from
Redhat 6.0 to RedHat 6.2.
The hardware is an older Micron Millennia
Mme, 200 MHz.

Subject: Re: Partitions
Date: Wed, 06 Sep 2000 14:53:03 -0700
Whatever is said in the how-to's, this has worked for me. I
have a 2GB drive with an old (does not support large drives)
motherboard.
IBM's Disk Manager software (originally installed from DOS).
This allows access to the area above 504M.
Partition 1 DOS/Windows C:
Partition 2 Extended (contains DOS/Windows D:)
Partition 3 Linux Native
Partition 4 Linux Swap
The first 2 partitions take up well over half the disk.
Lilo is installed in partition 3, and this is set as the
active partition. If I want to disable Linux I only need to
set partition 1 active, but even then I can start Linux
using Loadlin.
This originally ran using a 1.2 series kernel, but now has a
2.0.
I had no problems with Lilo being or looking outside the
first 512M. When Linux starts it detects the presence of the
disk manager software and does the right thing.

Of interest we used a bunch of that i860 bug as a
subprocessor in an older generation of graphics hardware. As
limited as it was/is as a general purpose engine it was
nifty where we put it. Gaggles of TI DSP's made the
Personal Iris gfx upgrades possible. We have built AMD
29000's into networking cards.... ARM's show up here and
there.... MIPS cores in ASICS too.
SGI used to use a Motorola 68020 to run its OS on... and
transition to the MIPS seeing the future at hand.
All in all SGI has been good at reading the tea leaves....
By no measure is the MIPS processor finished.
But the industry is a three ring circus. Today MIPS;
PA-RISC; and RS/6000 are in the center ring leap frog
jumping over each other. On another ring the ISA32 boys are
fighting it out. And in the third ring are the MEMORY and IO
guys.
Off in the wings are encores by all the players (clock ups
to the MIPS,,, additional pipelines etc.).
Out on the back lot some others are puttin a polish on the
new IA64 wild animal opening act. They know that others
were eaten alive by very long instruction engines.... But
today we have more transistors and improved compiler tools
to tame that beast. http://www.intel.com/pressroom/archive/releases/sp082200a.htm
Buy a ticket, get some cotton candy and enjoy the show.
Something new for all ages is coming....
For me the encores and sequels are the fun part of the game.
Stay tuned...

get a small (single disk) distribution like tomst from linux.org in the
distributions section. (needed for lilo to be reactivated.)
boot to msdos.
type fdisk /mbr
install NT
reboot.
put in tomst (or similar ) disk
login.
mount your hard disk
eg
mount /dev/hda4 /mnt -t ext2
cd /mnt
run lilo using /mnt/etc/lilo.conf as the config file.
i can't remember how but type lilo --help to find out.

I have exactly the same problem with the same kernel version (in RH 6.2)
with the Zip 100 Plus (on parallel port). The drive works perfectly on
RH 6.0 and with Win98 & NT 4.0. I think there is a problem with kernel
2.2.14-5 as far as imm & ppa are concerned, but I don't have enough
knowledge to sort it out.
No help, I know, but maybe someone else out there will see this and be

Date: Wed, 06 Sep 2000 15:12:11 -0700
I can't seem to properly set the locale with the glibc-2.1.3 that came
with my Slackware 7.1. Though I can change the LANG environment variable
and have the other LC variables changed appropriately, programs such as
kterm or perl insist in the following manner that the locale cannot be
changed:
Warning: locale not supported by C library, locale unchanged
Couldn't set locale:
ja_JP.eucJP,ja_JP.ujis,ja_JP.EUC,japanese.euc,Japanese-EUC,ja,japan
I tried to install a reconfigured glibc, thinking that locale support
had not been enabled, but even after configuring it thus:
./configure --enable-add-ons=linuxthreads,localedef
I still had the same problem. So help me I can't find any other
configure options or anything else to "support" locales. Is it just that
the ja_JP locale that comes with Slackware is broken? What am I missing?
(Everything on my system is the standard english version that came with
Slackware, except for Pine and XFree86 4.01, which is a binary from the
xfree86 site.)

But it dosen't have to be a bad web browsing platform.
for a os that prides it's self on stability with networking cap
why shouldn't it be able to handle web browsing with all the features.
unfortunatly my programing skills can't possibly hope to create a web
browser, but im sure some one out there could.
kfm is resonable for small jobs.
netscape is big (20 + Mb)
and crashes to often to worry about. (more than ie on 98)
this shouldn't be the case.

Well, I had the problem, but it was because I was coding the wrong
interrupt into the
/etc/conf.modules file. Once I got everything correct, my ZIP ZOOM
worked. (I am now using a more sophisticated SCSI card.)

Do you know of any current-production processor we could possibly
have been discussing which is actually single-issue?
As was very, very, *very* much made explicit in the thread you're
responding to, the poster I was responding to said that for his
code, the "MIPS" (I'm assuming R10000 or functional equivalent) gets
about two to three times the work done per clock cycle that the
IA32 does. This is totally unsurprising, if he's doing "floating-point
stuff" :-). However, clock rates on current IA32 processors have been
running at about two to three times those of current MIPS processors for
quite some time -- a rather depressing symmetry. Essentially, the inability
of the people fabbing the MIPS designs to get the clock rate up has almost
(or completely, depending what code you run) managed to compensate for the
horrific instruction set that the IA32 crowd are stuck with.
