Ja,
I don't have an answer for your question, but I noticed that you just did
the same upgrade that I just did. I was wondering, did you have any cd-rom
problems? and do you have a cd-recorder in your system?
I've got a problem with 2.2.17. I have a plain cd-rom reader and a
cd-recorder.
Both were working fine in 2.2.16, but with 2.2.17 I can't mount my cd-rom
reader.
Chris.

Boot from your boot diskette, mount your / device to /mnt
vi /mnt/etc/shadow
root:deleted_your_crypted_passwd:
umount /mnt
Reboot and you should be done, set a new root pwd, as you shouldn't have
one anymore!
Good luck

That may be what someone might _claim_ if they were ignorant.
The _real_ "whole point" of SVGAlib is that it's small, small, and
small.
That, in turn means that:
-> It's not got a whole lot of functionality
-> There's very little in the way of services that people could misuse
in ways that would make programs appear slow
-> Since it's small, it doesn't consume much memory, and so memory is
left to other things like cacheing disk accesses, thus making
everything else fast.
Since SVGAlib is so unfeatureful, and provides no ability to
"multiplex" with multiple applications connecting to the screen
simultaneously, nobody ever bothers trying to build ambitious
applications on top of it that could possibly turn out to be slow.
Paul Graham's comparison of C to Lisp is probably relevant:
In Lisp it is easy to construct software that runs very slowly; in
C, that is almost impossible.
The point being that any of the things you can do with C are likely to
run quickly, because the primitives are necessarily pretty quick. The
problem is that with C, you're likely to need to connect together a
whopping _lot_ of primitives in order to accomplish anything useful.
With Lisp, you likely don't need as many primitives...
In like fashion, SVGAlib may be quicker, at toy applications, than X.
But you're unlikely to see anything more than toy applications running
on SVGAlib.

Perhaps, did you read Documentation/Changes, I remember there were among

Subject: Re: help! new kernel - can't mount cdrom
Date: Sun, 25 Feb 2001 15:13:30 -0500
Glitch,
A. Yes on my system it is /dev/cdrom0, because yes I do have another cdrom
drive ( /dev/cdrom1 ), and yes I know they are both links to the "real"
devices, because I created those links myself (cdrom0 -> hdc, cdrom1 ->
hdd).
B. No its not /dev/cdrom, because I removed that link.
As I said, 2.2.16 works OK, specifically including "mount /dev/cdrom0"
so the device link is not the problem.
I think it has something to do with the 2.2.17 ide-scsi module.
I think its aggressively "taking over" both cdroms, whereas with 2.2.16
it just uses hdd like I told it to.
Thanks anyway.

Subject: Linux partitioning question
Date: Sun, 25 Feb 2001 12:32:56 -0800
I'm reading up on setting up linux, and it states that many will setup
separate partitions for /usr and /home besides ones swap space. I would
like to ask you how you usually setup your partitioning. I was a little bit
confused on it, for you at least need a mounting point of root. This is how
I did it, but I'm not sure if it's how it should be done. I set one
partition for about 3/4 of the drive as '/'. I thought that would cover my
separate partition for /usr as well as the mount point. My second partition
and about 1/4 of the drive (not all, as the last is for swap) I set as mount
point /home. Then of course the remaining 256 megs I set for swap.
At first I was going to create a 7 meg partition just for mounting root,
then the larger 3/4 approx for /usr, and then the last primary for /home but
I thought it just made more sense to make just a / and /home partition.
Maybe I'm just not thinking about this correctly. Any suggestions would be
appreciated!
I'm running Mandrake 7.2

From: "David" <[EMAIL PROTECTED]>
Subject: audio CD's
Date: Sun, 25 Feb 2001 20:22:10 GMT
The answer may be more complex that anyone can figure out, but hope someone
can.
Tried Mandrake 7.2 and RedHat 7, but no sound.
Used sndconfig and says found cs4232 card and that didn't work. I knew I
used Soundblaster in Dos so tried that. Worked, but read on.
By the way, my sound card chipset is CS4236/37/38 according to SiSoftSandra
and the MIDI is Crystal FM Synthesis and the Auxiliary Devices I/O is CS4232
Codec. On the Motherboard.
In /etc/modules.conf reads.
options cs4232 io=0x534 irq=5 dma=1 dma2=0 mpuio=0x300 mpuirq=11
alias sound-slot-0 sb
options sound dmabuf=1
alias midi op13
options op13 io=0x388
options sb io=0x220 irq=5 dma=1 mpu_io=0x330
1) Sound worked in sndconfig, Midi didn't. Went out and sound didn't work.
Removed the mpu_io=0x330 from 'sb options' and sound works. Had to do this
in both Mandrake and RedHat.
2) Is is possible that since the cs4232 doesn't have an alias is why it
doesn't work?
3) Tried a couple times removing this or that and that didn't work. Might
just not have hit the right combo or maybe something is missing.
4) I am sticking with the RedHat 7 now. Mandrake after several installations
would write my fstab file all wrong and had to reconfigure it.
So if someone knows how to fix in RedHat 7 that is what I am using.
Tried playing several audio CD's and they don't work, says it is playing
them, but no sound. Sound is enabled and looks like everything is installed.
Sound for events works fine now that I got the 'sb' in, but that is all that
works for sound.
Help Pretty Please.

Thank you, Michael, for your reply. I booted from the boot diskette,
entering linux rescue, as instructed. However, all that happened was the
beginning of the installation procedure. I did the same from the cd - linux
rescue at the prompt and again, the installation procedure started.
Perhaps, one cannot enter rescue mode from either the boot diskette or the
cd? Is this trur?

Subject: Reserve fraction of CPU time on server?
Date: Sun, 25 Feb 2001 13:01:04 -0800
Hello,
I have a 2 CPU P3-1GHz Linux RH 7 (2.4.0) server. The server is used as
a file server (SAMBA) but users can also run scientific simulations on
it (MATLAB/C). The problem is that when there are more than 2
simulations jobs running at once, both CPUs are used and the file
service becomes sluggish. How can I reserver a certain amount of CPU
time for the kernel/samba?
Please reply by e-mail.
Thanks,
Eugene Grayver.

Those who have more should pay more. It's not fair, but neither is how
those who have more got it, no matter how you try to deny it.
That's my proposal to "deal with it." as you state above.

No but the govt. subsidizes the poor with food stamps and the Earned Income

The govt isn't in it for a profit, but for the benefit of their constituents.
They need not be fair about their practices when their practice has a higher
overall benefit for all their constituents.
But as I said from the jump, we agree to disagree, so this is my last post on
