My mobo has the usual options of EPP and ECP, but also has an EPP + ECP
option. Some of the "extras" I occasionally use on my port need ecp, and
some work better with epp (notably a parallel zip drive). The mobo settings
imply that the port can be switched from one mode to the other in software
if EPP+ECP is selected, and indeed windoze does seem to do this (Hurrah!
Bill got *ONE* thing right!). However, under Linux, it always seems to
default to ecp with the ensuing dismal zip drive performance.
Is there a way of "persuading" these ports to adopt one mode or the other,
or do I really have to go into the bios and reset it everytime I switch
from using the zip drive to the other devices. (The other problem is that
Win2000 only recognizes the port as ecp+epp! If I set it to epp only, it
refuses to acknowledge the port exists at all! Take away Bill's brownie
points :-(

Hi Christophe:
Does your video card use part of your memory? Try reducing the memory
from 384m to 376m. To be on the safe side, reduce it even more, such as
370m. if this works, slowly increase the memory until it fails and then
back off some.

Subject: Hard drive is *really* slow
Date: 30 Mar 2001 18:29:54 GMT
I have a Maxtor Diamondmax 20G (92041U4) hard drive which is incredibly
slow on my Linux system. To wit:
% hdparm -t /dev/hda
/dev/hda:
Timing buffered disk reads: 64 MB in 147.96 seconds =442.93 kB/sec
I'm running the "unified" UDMA patch (from Andre Hedrick) on 2.2.18pre21.
I've tried just about everything -- played around with the settings using
hdparm, rearranged the master/slave configurations (there is another, older
hard drive), and even booted kernel 2.4.2 in the hope that it would better
configure my hardware. No luck.
Incidentally, tweaks with hdparm had absolutely no noticeable effect. That
is, when I set 32 bit I/O (hdparm -c3) and multi-sector (hdparm -m16) options
I did not notice a difference on the thouroughput. Yes, I've got a "double"
UDMA cable.
Details on the drive and my dmesg are below.
Thanks,
Matt

Date: Fri, 30 Mar 2001 18:37:43 GMT
Thanks to all who responded, the -pad option to the cdrecord command
was what I was missing.
=================================================================
Hello All;
I'm using some instructions I found in an earlier post to try to
convert some mp3's to wav and burn them to a CD using cdrecord. I
have come across a problem that was not addressed.
I convert the mp3 files to wave with:
splay -t 1000 -d - file.mp3 | sox -t raw -r 44100 -s -w -c 2 -
file.wav
I issue this command to burn the data:
cdrecord -v speed=4 dev=0,0,0 -audio *.wav
But, cdrecord responds with:
cdrecord: Bad audio track size 31707648 for track 01.
cdrecord: Audio tracks must be at least 705600 bytes and a multiple of
2352.
I can burn audio CD's normally if I get the data using the cdda2wav
utility.
Any pointer would be appreciated as to how I should change the size of
the resulting wav file, I didn't see an obvious switch in the splay or
sox commands.
Thanks in advance.
PS. I realize I can probably install some other utilities to do this
BUT this solution is supposed to work and until I understand what is
wrong here I'd like to try and make this approach work. Also, using
this method I can batch process files a lot easier.

Reply-To: "M.K.Venkatesh" <[EMAIL PROTECTED]>
Hi,
I am trying to get networking started with RH Linux 7.1. The Network Adapter
I have is SN 2000 P (PNP ISA version). The IO is 240 and the IRQ is 5. These
details I found from Win 95 running as a dual boot on the same box.
This is a summary of the things I tried.
. I ran Linuxconf and tried to add the IP address, Host Name IO port and IRQ
in the Basic Host configuration. This did not work. I get delaying eth0
initialization.
. I ran pnpisa and added it as a module in Linuxconf. I found that the
pnpisa wrongly puts the IRQ as 3. I edited the pnpisa.conf and changed IRQ
to 5. I then rebooted the machine. The pnpisa module at boot time shows
OK( actually this shows OK if the IRQ is 3 or 5). However eth0 is still not
successfully initialized.
. I again ran Linuxconf and this time I added the module name as detected by
pnpisa as AXE 2010 and added IO port and IRQ in the Basic Host Information.
The same settings have been added in modules.conf with Alias AXE 2010 and
setting. Upon reboot the same error is displayed delaying eth0
initialization.
. On checking the linuxdocs, the advise is to run modconf and add a module.
The utility apparently seems to have been removed in RH Linux 7.1
Any advise would be appreciated.
Thanks,
Venkat

Try turning AGP down to 2x or 1x. My Xserver has been unstable at 4x,
and I get no performance gain at 4x. However I suspect that won't help
you if it is segfscking.
On any given day, I'd say there's about a 2/3 chance a CVS build will
work for me. When I get a stable build, I archive it. I've actually
got a few stable builds archived so I probably won't blowing off any
more time doing CVS downloads untill they've added some
performance/features to make it worth the time.
So all I can say is keep trying, as you have time to do so of
course. If you get the same problem over and over agian post it on the
dri-devel mailing list. When you get a build that works, be sure and
archive it (tarball /usr/X11R6-DRI) before you try installing any new
builds.
>It won't be long before the CPU is a card in a slot on your ATX videoboard
Oh Gosh. Your CPU scheduler and ISR's will be modules inserted into
