RE: [CentOS] How do I identify my hardware?
by Mark Hull-Richter 25 Jan '07

25 Jan '07

So if it's not there, does that mean the device is not supported on Linux? Yoik. Neither of the video ids is in the list.... My audio id is there - it is the integrated mobo audio, but it failed initialization - does it need something to be plugged into it to work?

What I do is # get plain-language pci listing lspci # get numeric only pci listing lspci -n Match the plain listing with the numeric listing to get the raw PCI ID of the device in question, e.g., # plain language 01:0c.0 Ethernet controller: Intel Corporation 82540EM Gigabit Ethernet Controller (rev 02) # numeric 01:0c.0 0200: 8086:100e (rev 02) Then head to the Linux PCI ID repo and search for the specific ID ($3 to awk :-), in this case, "8086:100e": http://pci-ids.ucw.cz/ In this case, 8086 is an Intel vendor ID and 100e specifies a '82540EM Gigabit Ethernet Controller' device. -- Paul Heinlein <> heinlein(a)madboa.com <> www.madboa.com _______________________________________________ CentOS mailing list CentOS(a)centos.org http://lists.centos.org/mailman/listinfo/centos

How do I identify my hardware?
by Mark Hull-Richter 24 Jan '07

24 Jan '07

I'm a little new to CentOS and very rusty on Linux in general (it's been 7 years since I worked on a Linux kernel), so this may seem like a dumb question. I have two issues with my machine - sound and video. My sound card is not recognized at all (I think it's on the mobo, but I'm not sure how to identify it), and I have an ATI dual video card with two screens, but both show the same output, so I'm guessing that my CentOS does not know what it is, either (they show up as unidentified in the config file). I'm running 2.6.9-42.0.3ELsmp and can't upgrade to a newer kernel for the time being. Any suggestions? Thanks.

System hangs at "Rebooting System" on VIA KM400 chipsets
by nethub＠gmail.com 24 Jan '07

24 Jan '07

Hello, We have a number of systems running KM400 chipsets from VIA (Socket A/462). Two different models have produced the same results -- DFI KM400-MLV and MSI KM4M-V. When a /sbin/reboot or /sbin/shutdown -r now is issued, the system does everything you would expect from a reboot, but when it gets to Rebooting System, it hangs and requires a power cycle. The logs do not indicate anything is going wrong. It's not a kernel panic. I've tried appending "acpi=off noapic" or just "apci=off" to grub.conf and neither help. We've tested these boards extensively with various CPU's, hard drives, and RAM and they show no other issues, so it's not hardware defects or hardware compatibility issues. I'm not sure what is going on, but assistance would be greatly appreciated. Thanks.

RAID performance design? /home and os
by Christian Nygaard 24 Jan '07

24 Jan '07

I'm considering how to design a new file server with a 3ware 9650se RAID controller. How much would you estimate the impact to be on sharing /home and the operating system on one raid 6 set? /home is mostly read only accesses with a ratio 10:1 read/write. I'm a little bit concerned that the log writes in /var/log could impact read performance on /home causing disk head movements or that a little/non issue with modern Raid controllers? What would give best performance Scenario 1 8*500G Raid 6 /home and operating system Scenario 2 6*500GB Raid 6 /home 2*250GB Raid 1 operating system Looking for feedback Chris

Centos 4.4 in a cf card + ramdisk
by Erick Perez 24 Jan '07

24 Jan '07

I want to install centos 4.4 in a CF card and use a ram disk for operations. It means no hard disk attached to the computer. The machine will only run an antispam antivirus gateway. What documents can I read to make /var and /tmp sit on a ram disk and boot the operating system in read write and switch to read only after booting? thanks, -- ------------------------------------------------------------ Erick Perez Panama Sistemas Integradores de Telefonia IP y Soluciones Para Centros de Datos Panama, Republica de Panama Cel Panama. +(507) 6694-4780 ------------------------------------------------------------

How to configure CD-RW in CentOS for cd burning using cdrecord
by balajisundar＠midascomm.com 24 Jan '07

24 Jan '07

Dear all, I am using CentOS 4.4 Version Now.I want to Burn multi session CD using commands "mkisofs" and "cdrecord" on command prompt. I don't know how to configure the cdwriter(Samsung)? I am able to find the device using "cdrecord -scanbus" but when I want to get next track of already written cd using "cdrecord -dev=X.X.X -msinfo", system displays error and I am unable to get the next track. Previously, I was using Red Hat Linux 7.2, for that I have configured lilo.conf and fstab file as adding "append hdX=ide-scsi" and "iso9660 X,X,X,X 0 0" respectively. I have a scsi card which is already loaded and I can see the entry in "lsmod". Same 7.2 configuration is not working and even I also don't want to continue with that as CentOS supports cd-RW/DVD as default. Can any body help me to figure out the problem and advise me to take necessary steps do fulfill the requirement. I don't want to use K3B or other as I have some data and I want to make this cd burning process automatically in incremental manner into CD. Looking for a fast reply. Thanks in advance.. --Regards S.Balaji

wireless question
by Jimmy Bradley 24 Jan '07

24 Jan '07

I've had no luck with getting a wireless card to work. Before I go buy another card, I wanted to see if there is a way I could do this instead. I've got a second wireless router that I'm not using right now. So I would like to find out if there is a way I can make this work. I was thinking about connecting the second wireless router to my pc through the ethernet port, and let the router be my wireless connection instead of a wireless card. Now, is there a way I can get the second router to talk wirelessly to the router that's connected to my broadband modem, and surf the web and everything else that way? Any help would be appreciated. Jim
