Hi
Does RedHat 7.0 works on a notebook with chipset SiS 630/540?
I tried to install but during the kernel loading I got this message:
Kernel panic - Attempted to kill the idle task!
In Interrupt handler - not syncing
And with the kernel 2.4?

Subject: ide-scsi and ls-120 drive.
Hi - i have come across a niggling little problem.
on ide0 are 2 hard-drives, and on ide1 is an ls120 ( master ) and smasung sm308b
dvd/cd-rw combo (slave)
i have got cd writing working using the ide-scsi emulation.
I have set up the ls120 to be a scsi ( emulated ) device, but it can only mount disks
( 120M and 1.44M ) readonly, and the software
eject no longer works. ( all worked fine as ide-floppy ).
what am i missing ?
kernel version 2.2.18 - slackware7.0.
IIRC when the ls120 was introduced the only way to use it under linux ( cannot
remember which kernel) was under scsi emulation.
TIA

I used to use one of these (a TapeStor 3200 which I believe is essentially
identical to the CTT3200) until about a year ago when I bought an atapi drive.
The CTT3200 and the Conner card should work fine with the vanilla ftape
in kernels 2.2 and 2.4 -- you will have to supply I/O port, IRQ#, and DMA#
as parameters though (in modules.conf or as compile-time options).
Unfortunately the ftape "maintainer" hasn't sent a single update to the
official kernel for several years now, so there's a big difference between
the in-kernel driver and the one you can download from the ftape site.
Either version should work with your hardware, however.

Yup. I know that, but on the other hand, I've not seen a RPI modem
on the market for a very long time. And I've definitely never seen
a 56K RPI modem at all.

That's news to me, then. I was always under the impression that the

isn't capable of providing.

All,
I discover that the problem with my ATI Xpert 2000 Pro is the TV-out option,
if when turn on the computer there is connect a RCA input jack to the card
the screen goes black when running startx, in other hand, if the RCA input
jack is not connect when turn on the PC, startx works fine. These two
options occurs with Suse 7.1 and Mandrake 7.2 Linux versions.
This option I try on Red Hat 6.2 as soon as possible, perhaps occurs the
same.
The manual say that when the TV-out is connect, the monitor has support
refresh rate 50Hz and the 600x800 maximum resolution.
I see the XF86Config file and there is not monitors definitions with
refresh rate 50 Hz.
Regards ... Paco.

Funny. I had several hundred 720k disks which I formatted to 1.44mb
during the late 1980's. Never had a bit of problem. Spot checks
now show no problem. I had a lot more problem when I started buying
1.4's. Now if you talk 1.2mb vs 360kb, then you have specs that are
truly "quite different"

Doesn't actually eliminate the flux reversals. MFM (modified
frequency modulation) required clock bits, RLL (run length limited)
does not, but uses the data as a clock unless the run length was too
long, at which point it inserts a clock pattern.

But both media surface and inaccurate head positioning would affect
MFM just as much. MFM has no greater tolerance for media errors or
head positioning that did RLL. The only issue was electronics...
Could the electronics accurately clock the greater amount of data,
or would noise and latency issues disrupt the signal.

Subject: Networking -- switches vs hubs ??
Date: Tue, 24 Apr 2001 11:46:18 GMT
I've just picked up some hardware for making a network, and reading in the
accompanying manuals, I see "switches" and "hubs" in a baseT network are
either same thing for practical purposes -- or different; and I can't guess
which out of the manuals. The "switch" I have here is a Linksys EZSX55W
5-port switch Version 2.0. Apparently it's appropriate and I can use it to
network a few desktops and laptops that I have in my home; but I'd like to
be sure.
Can someone advise me on this?
<comment> My above is really an amazing question. A few years ago most
people thought it was remarkable if not extravagant, to have *one* computer

array). For someone who grew up in the 1930's, this is unexpected and
runaway-velocity change.

Subject: IDE DMA reset on spin-up
I'm having a problem with an IDE drive. It's a Western Digital 27 GB
drive that's a couple years old. I have it set to power down after ten
minutes with:
% hdparm -c1 -d1 -X66 -k1 -K1 -S120 /dev/hda
as well as manually setting DMA mode and telling the driver to keep
its settings. However, after the drive has spun down, I frequently get
the error:
hda: timeout waiting for DMA
ide_dmaproc: chipset supported ide_dma_timeout func only: 14
hda: irq timeout: status=0xd0 { Busy }
hda: DMA disabled
hdb: DMA disabled
ide0: reset: success
This apparently happens because the drive takes quite a while to spin
up, about ten seconds. This sucks because the read performance for the
drive drops from about 22MB/sec to 5MB/sec after the DMA is disabled.
I have a second IDE drive that spins up in about two seconds and I don't
have the timeout problem with it.
So my real question is what part of "keep_settings" does the IDE driver
in the 2.4 kernel in Red Hat 7.1 not understand? In the mean time,
is there some way to increase the IDE timeout to about 15 seconds?
The driver should do something like this anyway since it knows, as
evidenced by 'hdparm -C', when an IDE drive is active or suspended. It
should automatically use a longer timeout when the drive in question is
suspended.

When good dithering is used? And at high resolutions (which makes the
dithering more effective)? If you say so, but 16-bit is essentially
undistinguishable from 32-bit, to me under these conditions, and
there's nothing wrong with my color perception that I'm aware of.
If it were not for a few professional applications where color is
vital, the world wouldn't miss "true color" at all, IMO. Of course,
with modern hardware, it's like "why not" use true-color.

Both /sbin/reboot and shutdown -r now exhibit the same behavior.

A switch isolates the connection from one machine to the next. A hub allows
everyone on that network to hear. Because of this, switches have more complex
circuitry and are more expensive than hubs.
In a home network with minimal traffic a hub is all that's needed. In a larger
environment switches make better use of the bandwidth.
