I currently have four old SCSI disks which I would like to use and I've
heard that RAID0 disk striping is possible through a standard SCSI card.
I know software RAID1 is possible now, but what about RAID0.
The main reason is for hard disk speed. I believe that striping does improve
disk performance but can anyone give me an idea of how much or is it just a
waste of time trying?
I use Mandrake 7.2 but have installed kernel 2.4.
Thanks for any info.

Yes, I also had to use mknod as Slackware only installed 16 partition
devices for each IDE disk. So, what does your /dev/hd*17 look like? My
/dev/hdc17 looks like this:
brw-r----- 1 root disk 22, 17 Jan 21 2000 /dev/hdc17
That is a block device with major number 22 and minor number 17.

/dev/hdd has major number 22 and minor number 64, so you will only be
able to have 63-1=62 partitions.

You will only be able to have one extended partition with logical
partitions inside, but the limit is 62 as you have 63 partitions, but
one of them is only containing other partitions. For more info, see the
file /usr/src/linux/Documentation/devices.txt

I then tried the lsmod (to list all the loaded modules to see whether
the wished modules are installed or not.
The result is the following. To me everything seems to be ok. Does the
possibility exist, that the loaded driver bttv and tuner are not capable
of driving the WinTV-PCI FM but only the WinTV-PCI? Or might there be a
problem between the sound modules (I use kmp3 which was loaded when I
tried the kWinTV)?
Actually I tried to unload all the sound modules with rmmodule and
started kWinTV again....no success. (Only that clicking on the "sound
symbols" in kWinTV crashed kWinTV....probably missing sound modules :-))

By not being able to access, do you mean that they won't play? If so I have
this symptom too. Under KDE the cd player reports that the cd is 'ejecting'
when the play button is pressed.
It's an ATAPI IDE cdrom drive running with UDMA33

They're fast. Terribly fast. But unfortunately, they're also terribly
expensive. Intel chips are to the point now that on a dollar-per-FLOP,
they're either even, or slightly ahead of the Alphas, it seems. Of course,
that only applies to a point - Intel chips only come up to 4-way, once you
need more power than that, then it's Alpha or Sun.
(Or, the new IBM setups with 8 CPU's per module, but that will be quite a
bit of dinero...)

Yes, that is a very potential downside if he wants to do graphics. For
us, a terminal's a terminal, so we just stuck in whatever PCI card we could
find. They're tough to find, these days! (which makes it hard to do MDA
setups...)

I have a 5000e, but things are mostly similar. You need XFree86
4.0.2, or a patched XFree86 4.0.1 to get this working properly.
Redhat 7 comes with a patched XFree86 4.0.1 which works. Mandrake 7.2
comes with an XFree86 4.0.1 which doesn't work, at least on mine, but
if you replace /usr/X11R6/lib/somepathIdontremember/r128_drv.o with a
newer one (like from RedHat), it works.
Check out <http://groups.yahoo.com/group/linux-dell-laptops/messages>.
A month or two ago there were lots of messages just like yours, and
lots of answers from people who had it working.

You will save yourself some money and aggrivation if you just
add a Hauppaguge WinTV card to your existing video card. ATI
has terrible support, espicially if you also run other
operating systems. The WinTV cards are supported on most if
not all operating systems that support video capture. When
you want to upgrade to a faster video card, you also don't
have to throw away video capture, or pay more for it, since
they are separate cards.

There are MPEG2 and hardware MJPEG cards with Linux support.
Infact there is an MJPEG card that does full PAL and NTSC
resolutions made specifically for Linux.
VHS/NTSC->DV sounds like a nice gadget to have just in the
TV room. Although, I imagine the MPAA would try to squash
such a thing.

Since I compiled and installed 2.4.1 on RH 7.0, I can't get XCDRoast to
work. (Xsane doesn't seem to work either -- that may be a clue. Neither
seems to find the devices?!
Now the CD and CDRW -- both SCSI -- seem to work fine for reading CDs,
even the UDF (which I compiled in or read but not write.). [CD is NEC
466, CDRW is Yamaha 6416s]
The aic7xxx is configured as a module. It loads okay to mount CD / CDRW.
It shows up (with the CD and CDRW identified) during booting.
When I do insmod, however it just loads the module, and doesn't give the
rest of the info -- but the CD & CDRW work this ways as well as
automount from KDE. ?? probing problem??
I did NOT put SCSI-emulation in the kernel -- but then again that's only
for ATAPI-IDE. I have no ATAPI-IDE CDs.
Any help would be appreciated.
