Reply-To: [EMAIL PROTECTED]
I have the buggy CMD604 IDE chipset on my system, so in order to boot with both
my HD and CD, I need a kernel w/ the support for the chipset. I have compiled a
minimal kernel to get this functionality.
What I want to do is replace the default kernel on the RedHat Boot disk with
this modified kernel so that I can use the RedHat CD to install RedHat on the
system. I tried simply rm'ing the old kernel and cp'ing the new kernel to the
floppy. When I try booting with this disk, I get an "invalid kernel" error
message.
Or, maybe this is the problem: I thought the only difference between 'vmlinux'
and 'vmlinuz' is that the 'z' tagged file is gzip'ed. So that's all I did to the
newly rolled kernel. Is this the right way to do that? (I need to do something
in order to fit it on the floppy).
Any advice is greatly appreciated! Thanks..

I'm running RH5.2 on a pentium 233. I've got a Buslogic pci scsi control=
ler,
with seagate HD, scsi cdrom and HP travan scsi tape drive. I've been run=
ning
this machine for over a year with pretty much the same set up. I ran a f=

system backup, to the tape drive a couple days ago. Then last night I st=
arted
to run a backup of my Win98 pc, over the network, and the tape drive just
stopped responding. Now I can't initialize tapes, or access the drive in=
any
way. The unit is still detected by both the controller bios, and linux.=20
Looking through the log files I've come across the following -=20
kernel: Unable to get major 9 for SCSI tapes
and also=20
kernel: st: Unloaded
The latter appears after I try to use the unit. So, does this look like =
a
hardware or config issue ? Any ideas ? Thanks.

There's a program in the bttv or xawtv directory to make a
backup file for the contents of the WinTV EEPROM. Run it.
I then installed the drivers as per directions and didn't
have any unusual problems. The WinTV card works great!
Since it IS working, I'm leaving well enough alone.

Subject: Newbie -- Iomega Ditto Max Tape Drive
I am brand new to Linux. I have Redhat's 5.2 version
installed.
I have a Iomega Ditto Max Tape Drive that I would like
to use. In looking at various docs and getting a little
info from Redhat, it seems that I need both ftape
support and an application program.
How do I determine whether I have ftape support in my
current kernel? If I don't have it and must rebuild the
kernel, what option do I select from xconfig program to
give this support?
I would really appreciate some suggestions -- and a
copy of all replies to my personal email address.

Hi. I use the Viper 550 and it rips. I'm running RedHat 5.2
As someone else suggested you want to upgrade to XFree86 3.3.3.1.
http://www.redhat.com/support/docs/rhl/rh52-errata-general.html#XFree86
will give you links to all the needed files and directions.
Below is my /etc/X11/XF86Config file. It is for a 17" monitor, check
your monitors HorizSync and VertRefresh and change as neccessary.
Good luck! - Jonathan

Ummm...try providing support to multiple scientists developing code on
their personal workstations (x86 based), running multiple jobs on
multiple machines, writing data to the same location (typically a
partition on their personal workstation), using the generated (binary)
data as input to other jobs on other machines...add to that the problems
of maintaining some type of version control over the software being
developed...so now add to that simply *recompiling* *all* the code that
has been developed, and make sure that the version of code (and
compilers, and libraries and utilities, and...) are the same on both the
x86 *and* the alpha / ppc machines... And on top of all that, the data
produce MUST BE CORRECT!
So, while in concept having an alpha or ppc machine on the LAN with x86
machines is good idea, in practice there are a lot of minor problems and
it introduces a lot of places for bugs to enter the processing setup...

hi there,
total newbie here, first off i attempted to put a linux (rh 5.2) partition
and a linux swap parttiton both on my 2.6gig slave. for some reason it
failed and i am now left with a dud drive. i read somewhere else in this
newsgroup that a sililar problem was occuring with another person that had
seemingly done the same thing. my 2.6gig is now rendered useless as the
linux partitioning programs (disk druid and linux fdisk) cannot pick it up,
however the dos fdisk can pick it up but no changes to the partition can be
made. i don;t want to lose 2.6 gig overnight without a fight!! any help
whatsoever would be appreciated.

I believe that the Maven chip is responsible for the TV-Out functioning of
the chip, and only that. The actual mode switching is done by the G200
according to my interpertation of the documentation. I am working on this
driver as part of the Linux DVD project. http://linuxdvd.dhs.org
I am hoping to get a working TV-Out module in two weeks. (I need to get
the add-on for the G200).

possible to do it on Windows: you put a purple window in front of your TV

Subject: Some questions (hardware/software recommendations, issues/concerns, WTB,
etc..)
Date: 4 Mar 1999 18:39:12 GMT
I have a few questions. I run a mail server(pop accnts) on a NT box. I use to
have my own Linux box but that was sold. So, now I want to move my mail server
to Linux. But, I also want to be able to do a few things other than serv mail.
I want to use terminal/serial cards(isa/pci), raid(http://www.arcoide.com I saw
recommended), use of either a Oxygen or Intergraph video card. My current setup
is:
Pentium II 233MHz
96mb ram
9gig scsi hd
2x/4x HP SureStore cd-r
I can't find any drivers for my scsi card, so I will have to get a new scsi
card. So, I am wondering if people can make some recommendations for hardware I
am looking for. (also, any good grphical front-end to cd-record? or any good
cd-r apps?)
This is what I want:
Oxygen, Intergraph, or other Professional 3D Cards(is there a driver for the
Intergraph 3D Pro 20mb PCI? or any Oxygen cards(Oxygen 402 Quad Open GL, 102,
etc.?) But the g200 agp is supported? (matrox)
Camera (Quickcam? what interface?) I am looking for still/video/conferencing
A Linux supported dual Pentium II/III mother board(any one selling a P-II
233MHz cpu?)
RAID controller (http://www.arcoide.com a good choice?)
Also, a pop mail server for Linux that is easy to use. I know how to do
webbased email using sendmail, but I don't want that. I want to just serv pop
accnts and also to be able to easily add other pop accnts(free email, so you
can just sign up and the info gets added to the database). Use IMail server 4.2
and 5 for NT, so you get an idea of what I am used to.
Also, this box will be on a dedicated connection to the internet to serv mail,
but I also want to use it for personal use at the same time (compiling,
video-conferencing, newsreading, games, office productivity, etc.) So what do
you see as my experience being with my current hardware? (P-II 233mhz, 96mb
ram, scsi) How about running as a secondary DNS also?
Also, I want to add termial/serial cards to run xterms off of, and maybe have
some diskless clients. (please recommend!)
How about dual monitor support( I have two 20"..), and video capture? (link me
to what's a supported config or hardware).
How about TV-in/out? I wouldn't mind watching Cable TV while I am downloading!
My biggest concern is can I do everything I want on one box? And for links(even
offers) of hardware I am looking for that is supported under Linux. Use is fine
with me, as I can't spend too much.
Also, I know SGI is/has porting Linux to Indy's, but how about an Octane?
Please cc me any posts...comp.os.linux.* runs alot of traffic and I don't want
to miss any replies.
Also, if you think your system rocks, send me your configuration and which
distrubution you are running.
P.S...I am filled with questions..how about webpage templates? If I was to
offer webpages, is there anything like webpage templates for new users? (like
geocities.com has) for people who do not know html. And also, the popserver and
down the road, the webpage template/geocities thing will be used by Windows
user(just in case your recommendation was only a Linux-Linux thing..I need a
Linux-Linux/Windows/Mac/NeXT/Irix/etc thing)

Subject: BTTV problems with 1600x1200
Date: Thu, 04 Mar 1999 18:34:38 GMT
Hello!
I have been using Hauppage TV-grabber card (Stereo version with radio
support, Bt848) for few months. I haven't had much problems with it
until recently, when I upgraded my monitor to 19" (1600x1200).
With 1600x1200 resolution, TV picture gets misplaced a lot.
My setup is Matrox G200 AGP, XFree 3.3.3.1, BTTV with kernel 2.2.2
or with XawTV 2.3.7 (results are the same).
cat /proc/pci says that:
VGA compatible controller: Matrox Matrox G200 AGP (rev 1).
Medium devsel. Fast back-to-back capable. IRQ 11. Master Capable.
Latency=64. Min Gnt=16.Max Lat=32.
Prefetchable 32 bit memory at 0xe8000000 [0xe8000008].
Non-prefetchable 32 bit memory at 0xe4000000 [0xe4000000].
Non-prefetchable 32 bit memory at 0xe5000000 [0xe5000000].
so I guess correct value for vidmem is 0xe80. X -probeonly confirms
this and it is the value I have always been using. BTTV image isn't
misplaced with 1152x864 resolution. I also tried hardcoding vidmem
into bttv driver but that didn't work either.
I found other interresting detail about this problem when I compiled
frame buffer into my kernel. I'm running fb at 1600x1200 too, only
difference is that X is at 77Hz, fb is at 60Hz (haven't had time to
configure it yet). Now if I jump into fb window from X window that
had misplaced TV image, I can still see TV image and it is placed
on the exact position of where I had that empty TV window on X screen.
Maybe this is modeline specific problem? My current modeline is:
# 1600x1200 @ 77 Hz, 96.0 kHz hsync
Modeline "1600x1200" 199.68 1600 1616 1968 2080 1200 1200 1215 1254
Maybe I should try to run X at 60Hz too and see if the image is misplaced,
but I couldn't use it anyway so that isn't really a solution.
The problem can be seen on this screenshot:
http://www.iki.fi/jf/images/problem.jpg
PS: If it doesn't create too much trouble, would you please send your
responses also to my email address. Thanks!

That can be interpreted as meaning it supports 36 bit address spaces, so it
is a true statement.
It works in much the same way as, back in the "good old days," you had to
reprogram applications on the 8088 so as to support 20 bits worth of address
space using segment registers.
I am less than intimately-knowledgeable about that; I preferred at the time,
as a "Motorola-partisan," to skip over the grunginess of having to
continually write extra code just to address memory.

continually switched between the paging modes ...

Nope. It will intrude on all user code as well, because user code deals
with logical addresses, which must be mapped to physical addresses, and
therefore need to have an isomorphism to do so, ergo the compiler must be
modified to use the 36 bit addressing mode, libraries must be modified to
use the 36 bit addressing mode, and applications must be modified to use the
36 bit addressing mode.

It's a ton of work that pushes its way all the way from user applications on
through the "tool stream" to libraries, compilers, and the kernel.
Addressing is quite entirely pervasive.

The only things you've heard are comment concerning trying to support more
than 32 bits worth of memory addressing on 32 bit systems.
Linux has been doing 36-bit addressing on Alpha for a while now. There are
vendors selling machines with as much as 4GB of RAM. (Note that you can
only hold as much RAM as the motherboard can hold, based on the sizing of
available slots.) (See: <http://www.aspsys.com>)
It does not seem to be a reasonable idea to start tying the OS to an
odd-ball addressing mode that will hurt portability later, particularly
when:
a) There are on the order of a dozen architectures that Linux runs on,
b) various of which *do* support large memory spaces,
c) It appears likely that Xeon is merely a transitional processor to tide
people over until IA-64 becomes available.

that ok
during installation you will only see the harddisk partitions (not the
cdrom)
you can just continue it wil automaticily see the cdrom drive .....

From reports I've read, it does, but I haven't tried it myself...
I'm still using 2.0.36 with the ALSA drivers. They do fix those problems.
