Subject: cdrecord fails
Date: Thu, 27 May 1999 22:39:40 -0600
OK, I'm starting to get frustrated and wonder if there is a problem with
my drive. I have not been able to successfully burn anything under
Linux with cdrecord 1.8 and have also had problems under other operating
systems as well. cdrecord gives me more info than anything else,
though, and I wonder if someone out there could help me decipher what
exactly the error message is telling me.
I am attempting to burn copies of the Cheapbytes RedHat 6 CD, 634 MB in
total. I usually get through about 600 MB and then the bus appears to
lock up.
The drive is an Acer CRW6206A with firmware 1.3A.
The messages from cdrecord are listed below:
Identifikation : 'CD-R/RW CRW6206A'

The command I used to do this dummy burn (same thing happens during a
regular burn) was:
cdrecord dev=0,0,0 -dummy speed=2 /dev/scd0
Additionally, during the boot sequence, I seem to get a hard reset
during the device detection.
Kernel version is 2.2.5 as shipped with RedHat 6, recompiled for
ide-scsi emulation into the kernel.
My hard drive is on the integrated primary IDE controller, CD-ROM and
CD-RW drive are on the integrated secondary controller. I've tried
both:
* CD-ROM as master, CDRW as slave
* CDRW as master, CD-ROM as slave
This did not seem to make a difference.
The system uses an Abit BH6 system board. I have downloaded and applied
the latest flash ROM for the system. That also didn't seem to make a
difference.
Given the problems I'm having with the drive, I'm tempted to send it to
Acer for repair/replacement. It's outside of the return period to the
retailer, but definitely not out of warranty. I thought at first the
problem was media related - I had been using Memorex bulk media (50 CD
spindle) and had not had a single successful burn; however, switching to
Hi Val media has resulted in two failed burns, one successful burn, and
then the problems during this dummy burn.
Any help would be greatly appreciated. If you wish to e-mail me, please

Yes.
Notice, however, that there doesn't seem to be any work going on towards
providing support for 3D acceleration for the R-TNT's. If you want to do
Linux 3D, see http://glide.xxedgexx.com/ and consider the pros and cons

Didn't see anything about it during configuration, and my AGP card works

Granted, fragmentation is not much of a problem with any decent
filesystem, but if you are already moving the bits, why not?

Next week I'll be installing RedHat on my CD-ROM tower when it gets
moved from Novell over to a SMB network. I know that the stock install
does not have enough /dev/sd? entries to handle 28 SCSI cd-rom drives.
How can I remedy this situation so that I can use all of my CD-ROM's?
Thanks,

Try 'hdparm -tT /dev/hda' and reread quantium's page. 33MB/s is the
theoretical burst rate from the disk's cache. Also see the Ultra-DMA

To my knowledge, today's ext2fs on ix86 hardware can support file
systems upto 2 TB (2^31 blocks of 512 bytes). However, file sizes
are limited to 2 GB (which is not a problem in your case).
Now, ext2fs probably doesn't have a problem handling millions of files
in such large a fs.
Also, you might benefit of Linux's RAID5 features to create this huge
device. However, Linux, at this time, as no volume management: you cannot,
for example, extend a filesystem by giving it a few more
disks. However, if your files are on /big-disk/area1 and /big-disk/area2,
area1 and area2 can live on different filesystems, making expansion
possible, but painful.

These things are usually due to your monitor specs. Check your monitor

i was having a similar problem, and still am, in some repects with the
imm driver in the 2.2.9 kernel release. I checked through the
documentation of the kernel (referrence: parport.txt) and found that if
PNP support was loaded into the kernel there would be possible
problems. If my memory serves me right, the problems mentioned were it
would find it on another port, or not find it at all. Check out that
txt in /usr/src/linux/Documentation

Subject: Any benefit to tweaking the 3C900B optimization settings?
Date: Fri, 28 May 1999 05:23:36 GMT
I've got a 3Com 3C900B (10Mbps PCI NIC) card that connects my LAN's server
to a cable modem.
The 3C900B has 3 optimizations settings that can be configured with 3Com's
config utility:
1. Optimize for maximum performance.
2. Optimize for minimum CPU use.
3. Normal (balances performance and CPU use).
The factory default is setting #3 above. Given that this card acts solely
as a conduit for the packets transferred between the server and the cable
modem, I wonder if "max performance" wouldn't be a better option.
Any thoughts on this? Thank you.

that's odd. being an external modem, how would it know it what ttySn

One of the big features of AGP is the ability of the card to access the
main memory at high speed. e.g a 3D card using main memory for things like
texture memory.
I have a sneaking suspicion that the extra bandwith (2x and soon 4x) is
only for these special transfers. For normal sort of work (i.e "2D") it's
just your normal PCI speed. But I might be mistaken.

I second the G200. If you're coming from a Matrox Millenium II, you might
not notice much of a difference. I came from a $50 Virge 4M card and the
difference in the clarity of the picture was amazing. I've since heard
that Matrox cards have always had good picture quality.

... and a GLX (AKA OpenGL) module is in the works. I have a beta version
and it works pretty well. I don't seem to have enough memory to run full
screen with all of the acceleration (Z-buffers and the like), so I might
upgrade to 16M. Lower resolutions like 640x480 and 800x600 seem to provide
for some acceleration. I know the developers are working on optimizing the
code. Q3Test runs, but not very fast.

So, if a video driver has to be modified, I think it's very little - if at
all.
XFree86 3.3.3 supports most of these newer cards, including the G200 (AGP
and PCI versions). Don't know much about the TNT.
hope this helps,

The AGP and PCI#1 slots share an interrupt, so the freed up slot is not
usually that valuable. Given that the memory to AGP slot speeds are 5x
faster than PCI bus, I thought it would make a bigger difference. Try

for a dated but readable introduction to AGP.
