Need help configuring additional serial ports
by Alfred von Campe 23 Jun '06

23 Jun '06

I installed a 2 port serial PCI card on a system running CentOS 4.3, but I can't get the additional serial ports to work. The card I used is from StarTech (http://www.startech.com/Product/ItemDetail.aspx? productid=PCI2S550&c=US). When it is detected by kudzu, it shows up as a "NetMos Technologies PCI 9835 Multi I/O Controller". I've included the output of "lspci" and "cat /proc/pci" below. The (very sparse) instructions for Linux support for this card state that you should look for the string "serial port x" in the contents of /proc/pci, and then use that information with the setserial command to configure the port as follows: # setserial /dev/ttyS2 port 0xc000 uart 16550 irq 11 baud_base 115200 The problem is that I can't find the equivalent of the "0xc000" and the IRQ on my system in the contents of /proc/pci. Here is what the built-in, working serial port looks like: # setserial -a /dev/ttyS0 /dev/ttyS0, Line 0, UART: 16550A, Port: 0x03f8, IRQ: 4 Baud_base: 115200, close_delay: 500, divisor: 0 closing_wait: 30000 Flags: spd_normal skip_test auto_irq Any ideas how to get these serial ports working?

Installing from a usb drive
by Emmanuel Seyman 23 Jun '06

23 Jun '06

Hi, all. We've make custom isos of CentOS and having trouble during the installation. Here's what we did : Add our rpms to CentOS/RPMS Add a folder of scripts and two kickstart files to the base directory run "pkgorder /path/to/base i386 CentOS > /tmp/foo.txt" run "genhdlist --fileorder /tmp/foo.txt /path/to/base" rerun the pkgorder command Add a custom group to CentOS/base/comps.xml run "buildinstall --pkgorder /tmp/foo.txt --version 4.2 --product "CentOS" --release "BAR_V1" --discs "BAR" --prodpath CentOS --comp BARv1 /path/to/base" change isolinux/isolinux.cfg to add two labels, one for each ks file run "mkisofs -o foobar.iso -b isolinux/isolinux.bin -c isolinux/boot.cat -no-emul-boot -boot-load-size 4 -R -J -v /path/to/base" to generate the DVD iso. This iso works fine when we burn it to dvd and install from it but when we boot from DVD and select the kickstart file that installs from a USB drive, we get the following error : "trying to mount already-mounted image!" Could anybody explain why ? Emmanuel

x86 uniprocessor 4GB memory
by Bruno Sousa 23 Jun '06

23 Jun '06

Hi there, I'm currently using CentOS 4.3 (Server edition) in a HP DC 5100 with the IntelR 915GV chipset, powered by a PIV 3.0GHZ. Now I'm facing a problem, with memory. I got myself 4GB of memory, the system bios detects it correctly, but in Linux can only see around 3.5gb memory. With the default kernel-smp (I use hyperthread) or with kernel-hugemem , I have the same results. Is there any way to workaround this issue? Thanks in advance, Bruno Sousa

RE: [CentOS] x86 uniprocessor 4GB memory (fwd)
by Maciej Żenczykowski 23 Jun '06

If you have an AGP video card which you aren't actually using you can try selecting the minimum possible AGP apperture (window whatever) size (possibly even disable it?). This might help. Also removing the AGP card and using a junk 1-8MB svga card will also possibly work. In my experience the linear framebuffer of video cards is by far the greatest memory hog these days. Cheers, MaZe.

OT -- BASH
by Robert 23 Jun '06

Can someone explain why this: find . -depth -print0 | cpio --null -pmd /tmp/test will copy all files in and below the current directory -and- this: find . -depth -print | grep -v .iso$ | wc -l will count all the non-iso files -and- this: find . -depth -print | grep .iso$ | wc -l will count *only* the iso files -but- this: find . -depth -print0 | grep -v .iso$ | cpio --null -pmd /tmp/test doesn't copy *anything*? Any suggestions for a work-around would also be most welcome.

Hello, We're getting around to upgrading our mail server and here are the quick specs: MegaRAID SCSI 320-2X http://www.lsilogic.com/products/megaraid/scsi_320_2x.html TYAN Transport TA26 B2882T26U8H 2U Barebone Server-Rackmount - Retail http://www.newegg.com/Product/Product.asp?item=N82E16856152007 plus RAM, CPU and 4 SCSI drives setup in a RAID-5 Is that MegaRAID controller supported in CentOS4.3 out of the box? I really don't want to muck around with driver disks and the like. Anyone else have suggestions? Thanks, Ajay -- Satyajot (Ajay) Sharma REVShare System Administrator

HP DL360, tg3 driver, bonding and link flapping
by Michael Grinnell 23 Jun '06

23 Jun '06

Hi *, I'm running into a problem configuring bonding on an HP DL 360 G4p, running 4.3 + tg3 driver version 3.43f. I'm connecting eth0 and eth1 to a Cisco 2948 (CatOS 8.1(3)) and receiving flapping notices. The ethernet address is that of the primary interface. I have tried several different modes, including balance-rr (0), active-backup (1), and balance-alb (6). All have the same problem.
