Howdy all,
I wonder if anyone can provide any assistance regarding the
installation of the Promise Ultra100 ide controller under Caldera
eDesktop 2.4?
I've Googled the net and there isn't much info. Promise is of no use
and the Ultra100 isn't listed under the Hardware Compatability List.
Anyone else gotten this controller to work?
Any and all assistance appreciated.

I could not find the driver i2c.o anywhere on my system (Red Hat 7.1).
It existed in Red Hat 6.2. There is a driver in the directory
/lib/modules/2.4.2-2/kernel/drivers/media/video named i2c-old.o but
when loaded it does not resolve the i2c externals required by bttv.o
and tuner.o. What do I have to do to get kwintv to work in Red Hat
7.1? Why do things get so easily broken?

Red Hat seems to think this is a hardware problem, at least according to the
Installation Guide.
They suggest looking at: http://www.bitwizard.nl/sig11

Hi,
I am having sound problems on my linux system which runs Redhat 7.0 on
P111 - 400 , 128MB ram, and an i810 motherboard.
sndconfig did detect the 810 sound card but occasionally my system just
hangs when starting *any* sound. So when i start xmms I have a 50-50 %
chance that my system won't hang.
Anyhelp would be appreciated.
Thank you,
Raheel..

Linux doesn't get to influence which disk is booted, but it does

drive letter/device designation.

Well, actually, I was trying to do the opposite of what people hate --
I want to get some naming stability in the face of physical change.

I mean what drive letter/device designation to assign them. Thus,
the CD-ROM drive could still become /dev/hdb, even if the hard drive moved
(and no matter which IDE channel the CD-ROM drive was on).

I'll have to look into this. I might have found another option for

Use a variation upon the same idea. :-) Of course, this is a
somewhat trickier problem, due to the greater number of options for

I might have to try this out . . . or I might not. Last Friday I was
messing with a Red Hat 7.0 installation (as opposed to just the rescue mode of
the installation CD) for the first time. I noticed that /etc/fstab has
entries for hard disk partitions that begin with things like "LABEL=/" and
"LABEL=/boot". Intrigued, I tried to find out about this, and came upon ext2
disk labels, set by the "e2label" command. The upshot of this is that you can
edit /etc/fstab to find partitions by their ext2 disk labels. For some
reason, this option seems not to have been used in the Red Hat series before
version 7.0, but version 6.2 has the e2label command, and I tried it on a
MontaVista Hard Hat 1.1 system (almost the same as Red Hat 6.1), and the
system boots and mounts its file systems properly, except that it keeps giving
me this stupid error about one of the file systems being "already mounted"
according to mtab (even after I deleted /etc/mtab). My best guess is that the
"LABEL=" feature works almost right in earlier versions of the Red Hat series,
but was only fixed to work completely right in version 7.0. I haven't yet had
a chance to try moving that hard disk, though (I discovered this pretty late
on Friday). If this does what I need, it will solve half of the problem; the
remaining half of the problem will be to convince Lilo to point to the disk
that it is on rather than where the disk used to be.

Not sure if the OP got an answer to the kgcc thing (and I missed the
original post).
Look in the kernel source's toplevel Makefile and you'll see
CROSS_COMPILE =
I believe if you put the letter `k' there then make will use kgcc
(and other `k' stuff if they exist - I know nothing about RH's gcc
stuff layout).
In the Makefile is stuff like:
AS = $(CROSS_COMPILE)as
LD = $(CROSS_COMPILE)ld
CC = $(CROSS_COMPILE)gcc
which would then use kas, kld, kgcc, etc. I have no idea what happens
if it can't find a `k' utility such as kas, kld, etc.
Maybe just uncomment the CC line to CC = kgcc (??).

Actually, this was one of the first things that I did.
Lilo was installed on the 1st native linux partition.
Then SC2000 detected this new OS, but then gave an error message about the
boot information being in "error" or corrupted. I subsequently re-installed
and choose not to have lilo install at all, only from floppy.
My next plan of attack, re-install RH7.1, but this time I will mount 3
partitions,
/boot
/
/Swap
Will this automatically make linux put the necessary startup files in the
first partition (of the 2nd physical drive), such that SC2000 can reference
this OS?
I have found SC2000 setup relatively easy to use, because I can manually
specify the device and toggle if that partition is bootable or not. The
only area which I find difficult to understand is the way linux install sets
up boot information when lilo is not choosen. Seem like Linux install will
always assume that if Lilo is not choosen, the boot up information can only
be passed to the floppy disk. Thus my main question, how do I manually pass
the boot up information to the front of the disk, such that another 3rd
party loader can pick it up.
(c.f. like using the sys command in dos to transfer the necessary boot up
informatio to a HDD).
Thanks again in advance.

Will a PS/2 keyboard/mouse Y cable work on the PS/2 port on this
laptop? Then you could connect both a mouse and keyboard to it
simultaneously. These things cost about $6 or $7. You might still have to
stop and restart the mouse driver manually when you plugged in a mouse or
removed it. If so, use "gpm -k" and "gpm -t ps2" to do this.
If you have to switch between serial and PS/2 mice, I don't know of an
automatic way to do it, but at least in the Red Hat series you can run
"mouseconfig" to change your mouse configuration in seconds. If Slackware
doesn't have this command (and I don't know off hand which rpm it is in, and I
don't have a Linux machine next to me to look it up, and don't know if it will
work on Slackware anyway), you will have to stop, reconfigure, and start gpm
(the mouse service) manually (after you get it working, of course, write a
script to do this so that you just have to type 1 command). You might even
be able to write something to poll the mouse and serial ports periodically,
but right now this is beyond me. (Note: if anyone knows of a way to do this,
let me know -- the lousy Belkin KVM switchboxes we have at work often hose the
mouse, requiring the gpm service to be stopped and started manually -- at
least you CAN do that in a few seconds, unlike in Windows).

Greetings all,
I clean formatted Mandrake 8.0 and am lovin it, but I decided to poke
around the Mandrake Control Center to try out 1280x1024, instead of my
usual 1024x768. As I guessed, things were too hard to read. So I changed
the resolution back, and everything's fine, except for the fact that now
my background is stretched to 1280x1024. If I center it, it's also off
center. Seems something forgot to tell Gnome that the rest is back at
1024x768? How do I fix this?
Thanks,

Welcome to Linux-land!
Linux IS a workhorse, serving many masters (multiuser), so a mounted part
of filesystem tree cannot be removed by "anyone" as it can be used by
someone else.
First it has to be unmounted (usually by root). Even root will get "part
busy" notice if this part is accessed.
So "umount" (NOT a typo and no brackets) the device you want to remove and
try again.
Have fun.
