A brief update:
Both my scsi JAZ drive and IDE Zip drive do not show up under devfs after a
reboot.
However, if I try to mount my Jaz using the old command:
mount /dev/sda4 /mnt/jaz
it works, even though neither /dev/sda4 nor
/dev/scsi/host0/bus0/target1/lun0/part4 exist yet. After the mount they
do. Trying to mount the devfs location initially will fail until the node
/dev/scsi/host0/bus0/target1/lun0/part4 has been created by the old
non-devfs mount command above.
In order to mount my Zip disk I must first try mounting it with the old
command:
mount /dev/hdd4 /mnt/zip
and THEN reload the ide-floppy module, THEN try remounting using the old
command, after which the devfs node /dev/ide/host0/bus1/target1/lun0/part4
then exists.
Very odd. Any ideas why?

Subject: Problems with IDE HDD and DMA
Date: Tue, 13 Feb 2001 20:14:01 GMT
Hi!
I have an old P200MMX with Intel TX chipset. The mainboard is from
Chaintech.
My problem is, that my new 40GB Seagate HDD isn't detected in BIOS
(doesn't matter for me because I use an 80MB drive to load the kernel
and boot, and linux recognises the drive).
The real problem is, that since the BIOS doesn't recognise the hdd, it
doesn't initalise the IDE port and sets no PIO/DMA mode (which brings me
to a whopping rate of 2.8MB/s for my new 40GB drive instead of 9MB/s
with my old 10GB drive :(((
hdparm -X 33 or -X 34 (and even -X 11) didn't work either :(
any hints??
thank you!!

Subject: Sv: Linux on MPC860: OK? Or asking for trouble?
Date: Tue, 13 Feb 2001 21:26:15 +0100
I have just completed a project installing Linux on a PowerPC board designed
by the company I work for.
Linux works fine on the MPC860, just make sure you use the MPC860e version
as it has larger cache and has much better performance.
Reasonable Linux experience is important for this type of work. Without any
Linux experience you need to do some research on the desktop. See how the
kernel is compiled, experiment with the file system, drivers and the kernel.
This is a non trivial task and not suicidal either.
When starting our development, we first bought a working MPC860e target
(from http://www.embeddedplanet.com/) and installed Linux on that. When we
got it working we could rather easily move to our own hardware. I can
recommend this procedure.
Some information on Linux on PowerPC is available on: http://linuxppc.org/
and
http://www.penguinppc.org/usr/embedded/howto/PowerPC-Embedded-HOWTO.html. I
beleive the last link has a readymade Linux installation you can use.
Regarding question 2, if you are thinking in terms of application
development more information is needed. If you are developing graphical
software you need to install Qt embedded or something like Tiny-X on the
target and maybe use Kylix (Delphi) for development. Then you have
application code that is directly portable to Windows. If you are thinking
in terms of driver development all you need is on your Linux desktop, that
is the standard C++ compiler and some editors.
Hope it helps,
Karl

I think it's not possible because you need not only AIX jfs but also the AIX
LVM support. Otherwise linux can't import AIX VG's. I have never seen any
implementation of the AIX LVM for Linux. If there is any, than please inform
me about it.

I am one of those who can only get dialup (<28.8), T-1, or DirecPC. I
prefer DPC for the price/performance. I won't likely be able to get any
other options for a while.
I have been working w/ Windows in its various forms for about 10 years now.
Have never figured out how to keep the OS from crashing. Just not stable
enough for me. Also, Bill seems more interested in putting in everything
but the kitchen sink instead of concentrating on making a stable kernel.
I have found that my Linux box will run for months without requiring a
reboot. My Win9X's, on the other hand, need to be rebooted once per day,
sometimes more. Also, I frequently get a message from Nav that the PCI card
has stopped working and I need to reboot to get it working again -- so much
for Newscast!!!
This leads me to my questions, does anyone know of a way to get DPC working
on Linux/Unix. These boxes are so much more stable and come with software
to allow connection sharing --routing/firewall/IPmasq. -- whatever your
preference. I would appreciate any feedback I can get on this.

Subject: different /dev's for tape?
Date: Tue, 13 Feb 2001 14:03:08 -0700
Hi All,
I've got a QIC tape drive which has on-board compression. When I MAKEDEV'd
the /dev directory for the device, it created st0 and nst0 (rewinding and
non-rewinding) devices. This works fine.
But, my tape drive (a Tandberg TDC4100 or SLR3) has other modes, including
compression, etc. How do I get /dev entries for those?
How does anyone create different /dev entries for different modes for a tape
drive? Do you have to create an stinit.def entry for the device?
Thanks in Advance

Helius used to sell DPC drivers for Linux. However, they are no longer
taking new customers. Only _existing_ customers may purchase the drivers.
This question is asked at least once a week and the answer is always the
same.

Some Logitech wheel mice use intellimouse protocol rather than
MousemanPlus, try setting the protocol to imps/2. There doesn't seem to be
much logic to it, it's just a case of try one and if it doesn't work try
the other (I've got some Logitech MouseManPlus opticals at work that are
imps/2, while my Trackman Marble at home is a MouseMan Plus).
You also need to have ZAxisMapping 4 5 set. Even then only some apps will
recognize it (KDE2, recent GTK+ and to some extent xforms).

Use the major and minor device numbers found in the file devices.txt in
the linux source code (../linux/Documentation/devices.txt) or at the
website http://www.kernel.org/pub/linux/docs/device-list/
There appear to even be special devices for QIC tapes, to enable
compression. Make the devices with
/sbin/mknod NAME c MAJOR MINOR
For instance to create the deive associated with the QIC 117 tape drive
one uses the name qft0 for the first drive, and rewind on close, c,
since it is a character device, major 27 and minor 0
/sbin/mknod qft0 c 27 0
to make the device entry for the same device, Unit 0, rewind-on-close,
but now with compression,
/sbin/mknod zqft0 c 27 16

This is why you use cfdisk and mke2fs to create Linux partitions.
Anyway, the 2.4.x kernel series mounts partitions far more quickly than
the 2.2.x series, as well as increasing throughput wrt disk I/O.

http://www.gnu.org/software/parted/ ? Changing the block size of an
ext2 partition appears to be difficult; the default 4096-byte block size
mke2fs uses is appropriate for most ext2 filesystems on hard disks.

If you're having problems hearing anything at all, upgrade your kernel
to 2.2.18 ; the 5880 is actually a very-slightly modified es1371. There
*IS* no hardware MIDI on the es1371 cards; that's why they're so cheap.
Get "timidity" and you can do MIDI in software. Don't know what you
mean by "3D sound" or "effects" but then I have cheap speakers and don't
play the latest k3wl g4mes. HTH,

where hdan is the partition you have the problem on. If you only have
