Because Linux does something that DOS/Windows doesn't... It actually
uses the parallel port's IRQ. With the IRQ being called every time
data needs to be sent to the port, you're going to see a slowdown on
slower systems. The only real cure for this is to increase the size of
the buffer in your M410 (i.e. Add RAM).
Hope this helps.

Just consider that disks nowadays have more sectors per track on the
outer tracks than on the inner tracks. The outer tracks are longer
and therefore there are room for more bits. That is also how you
can try to multiply the CHS values and won't get a value different
from the total disk size.
The appearent geometry of ide disks is largely dictated by the number
of bits allocated to each of cyls, heads, and sectors. Read the
HOWTO/mini/Large-Disk for the gory details.

You already have SHARE_IRQ enabled - i.e., serial port IRQ sharing WILL
work, and you should ignore the other posters telling you otherwise or
to recompile your kernel. That's not the problem.

You said this was an old 486. 16450's were current back in 486 days, so
I guess that they are the 2 original serial ports, and that the 16550A,
being a newer chip, is the modem. So /dev/modem should be pointing to
/dev/ttyS2, not /dev/ttyS0.

Hallo,

He run good under MSDOS but don't work with SuSE 6.4 (kernel 2.2.14).
I probe it as module "t128.o", comes "... DEVICE BUSY".
And also hardcompiled in kernel will not work.

I picked up a dirt-cheap cheap Compaq Deskpro EN Celeron 333 machine
with a while back and got SuSe 6.4 co-existing just fine with WinNT and
Win98SE.
Using Suse's graphical YAST2, I got the built-in ESS sound to work
under SuSe (using info garnered from Win98), but even the slightest
interrupt-generating event (like moving the mouse) causes the sound to
get choppy. Makes for an unenjoyable MP3-listening experience while
working.
Is there some output buffer I need to set up or something? While I'm
not a UNIX newbie, I am not an expert and I *am* new to Linux. Any
ideas/suggestions would be most welcome.

ServerWorks' website makes no mention of AGP for the HE chipset. I does
appear however, that the HE and WS chipsets use the same northbridge and
southbridge chips, but have a different IO bridge chip, with the WS version
supporting AGP. Do you know of any HE based motherboards with AGP slots? In
fact, do you know of any HE based boards at all?! I have a machine I'd like
to upgrade to 64-bit PCI, but I need AGP as well.

Oh, I'd wish it was that easy. _Most_ of today's el-cheapo ISA modems
are 100% Winmodems. Motorola's AC56 is. The original WinModem (TM) is

This is your modem. It is incorrectly configured to be using IRQ 4,
which will not work. Use setserial to give the ISA modem an IRQ
of its own (check jumper settings on the card first).

If not configured otherwise, the parallel port uses polling, which takes
a noticeable amount of CPU power. You may configure the parallel port to
use interrupts or even DMA. How to do this depends on your configuration
(kernel version, parport support compiled into the kernel or loaded as
modules).
USB may be better. I have an USB scanner and do not notice any slowdown
of the system when scanning. Please not that USB is not fully included
in the stable kernels, but some distributions heve patched kernels with
USB support.

Find out, it is the new via-rhine II chipset, unfortunately can not compile
the new driver from ftp://www.scyld.com/pub/network/via-rhine.c there are
some header files missing. We use Suse 6.3 kernel 2.2.14
There is also a new driver available from D-Link but this driver does not
work either.

Aren't there problems concerning the System.map-file? If cpio just
copies everything to a non-identical-partitioned,
non-identically-geometried HD, then the kernel itself will complain,
doesn't it? And rerunning lilo wouldn't help, because you just can't get
to running lilo...

I ::could:: be wrong on this, but isn't DMA 1 supposed to be 8 bit,

If I'm wrong, I'm sure someone will correct me on this...
You might also try moving the sound card's IRQ to something between 9
and 12, inclusive. IRQ5 is one of the last to be polled, and that
could be causing the "choppiness" in your mp3 playback.
Hope this helps.

Date: Fri, 25 Aug 2000 11:38:58 GMT
Thanks for the reponse!
The problem is that the CD is damaged and all that mount sees (in
Linux and Windows) is the last session (about 1% of the total data
stored). The disk was written in 15 sessions and I can see all those
tracks.
I read about the mount session option BUT it is not available in my
Slackware 7 mount ... it must be very recent. This is not the best
solution however as for future reference I want to figure out how to
just read raw data tracks from the disk.
The skip option for dd is what I'm really looking for BUT trying
various combinations of parameters I could only read the first track,
I just couldn't determine the exact sequence of parameters.
To get the skip value, which utility would I use to determine the
offsets? Using cdrecord and -toc it provides sector numbers
(apparently). When I use dd to read the first track it responds with
the number of records ... doing the math this is the number of 512
blocks, not 2048. I guess dd is what I want to use BUT I'm just not
sure of the numbers to use and where to get them.
I'm at work right now so I'm not able to try the 2048 block size.
Any way thanks for the response and I appreciate the help.

My old Seagate documentation states that "most existing IDE drives do
not implement the SPSYNC signal [pin #28]". The word "most" suggests
that some older IDE drives may support SPSYNC. Do the EIDE and IDE
standards differ in this area, or have drive manufacturers chosen not
to implement this part of the spec?
