CentOS 5 :: Available RAM Not All Recognized?

Oct 27, 2009

I have 6 GiB RAM installed in a server. The bios shows 6. They're all identical sticks. The OS says there's 4 though. I'm not sure what to do now. Dell says it should be able to use up to 12 GiB.

# uname -a
Linux 2.6.18-128.1.10.el5 #1 SMP Thu May 7 10:39:21 EDT 2009 i686 i686 i386 GNU/Linux

CentOS 5 :: Disabled FakeRaid Still Getting Recognized

Feb 9, 2009

I can't get CentOS to stop seeing my drives as a fakeraid, even though I disabled the raid settings in the bios. Therefore, I can't install. Previously, this box was running Vista 64 bit. I have an nVidia mainboard and two 500 GB sata drives. The mainboard offered raid support, so I enabled it. Windows saw the drives as a single raid0 drive and installed on it flawlessly. Never had a problem. Two days ago, I finally got off my horse and decided to get rid of windows and install CentOS. I left the raid intact, installed CentOS on the fake raid. Upon rebooting, GRUB wouldn't load. Booted up a live disk, fdisk saw the drives separately but couldn't read data from them.

Tried a second install, same problem. Wiped out the the data on the drives using gparted. Tried a third install, same problem. Did some research, found out that my raid was really a fakeraid and that a better option for my needs is a softraid. Disabled the fakeraid in the bios. Booted up the installer. It still loads the nvidia /dev/mapper driver. It still sees the drives as a fakeraid. Wiped out the drives using gparted. Booted up the installer. Still sees the drives as a single /dev/mapper/nvidia_lkjwer drive. Installed Ubuntu to see if I'm crazy, or if it's centOS. Ubuntu installed w/o a problem (on a single drive). Enabled, disabled, tweaked every freaking possible bios setting. Still sees the drives as a fakeraid.

CentOS 5 Hardware :: USB 3.0 Controller Not Recognized?

Oct 13, 2010

I have just installed a NEC 3.0 PCIe board in my CentOs 5 box, but the card is not recognised, and no drivers seem to be loaded for it. lspci says: USB Controller: NEC Corporation Unknown device 0194 (rev 03) The vendor says the board is supported on Linux kernels 2.6.16 and later. uname says my kernel is 2.6.18-194.17.1.el5

How do I get this device to be recognised, and drivers loaded for it?

CentOS 5 Hardware :: Scsi Drive Not Recognized?

Feb 21, 2009

I just installed centos 5 on a hp dl380 server and it has 2 72.8 scsi gig hard drives. The problem I am having is that only one hard drive is being recognized and it is not being recognized as a scsi. This is what I get from fdisk -l

Disk /dev/cciss/c0d0: 72.8 GB, 72833679360 bytes
255 heads, 63 sectors/track, 8854 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System

/dev/cciss/c0d0p2 14 8854 71015332+ 8e Linux LVM

as you can see, the system doesn't even see the second hard drive. How do I get both hard drives to be seen and how do I get them to be recognized as scsi?

CentOS 5 Hardware :: Firewire Drive Not Recognized?

Aug 27, 2010

With CentOS-5.5, centos plus enabled, my LaCie external hard drives are not recognized even though connected and powered up before booting. I am logging in as root. Previous 2.4 kernel RHEL Enterprise 3 required a special scanning script which worked with this computer. This current system will not recognize the drives as hardware. On the other hand the drives with USB 2.0 ports automount connected with USB and also are recognized in the hardware list. what diagnostics to do to find out what layers / drivers are missing.

CentOS 5 Networking :: WiFi Card Configuration / DWA-110 Not Recognized

Feb 9, 2009

I have a problem to configure my wifi card, a dwa-110 from D-Link, it is not recognized when I launch System / network device control (only ethernet connections appear), and it is the same thing in Administration / network / network configuration. But if I launch administration / hardware / system devices, the last line is "Ralink 802.11 bg WLAN"... When I try to add in the window "network configuration" (from above) some new stuff, I specifying the kind of hardware (wireless) and when I have to enter the name of the card I don't see my card. On other OSes, I used ndiswrapper, but I wasn't able to install it on CentOS (dependencies required and it's hard with only a USB key to install the stuff...) How to see if the card is recognized, if I have to use ndiswrapper and so on. I have an internal PCI network card also, maybe it is this card which is recognized.

CentOS 5 Hardware :: ASUS M3A78-CM RAID1 Not Recognized

Aug 28, 2009

OS Version: CentOS 5.3
Motherboard: ASUS M3A78-CM (BIOS v.2003)

I have a single disk running the base OS and just installed 2 x Seagate 500GB SATA 3.0 drives in a RAID1 set that I would like to use for data storage. The OS sees the drives individually but not the RAID. Has anyone worked with a similar board and has any ideas what I need to do to get the OS to recognize the RAID1 array?

CentOS 5 Hardware :: Belkin USB Gigabit Ethernet Adapter Not Recognized?

Aug 12, 2010

I have spent them with Fedora and liked it a lot. Today I decided to install CentOS as this looks like something I would like to be using in the future. However a problem I could not solve came right at me after the first boot.

I have one eth0 device which is onboard lan and that was correctly recognised and activated. The second device is F5D5055 Belking USB Gigabit ethernet adapter. There was no problem with it whatsoever under Fedora. According to all the info it should be automatically recognised on kernel 2.6.14 and later. However when I plug it into the USB port, I can see its correct name in the device manager but it is not recognised as a network device. I have configured my Fedora as a firewall/router for my lan and definitely want to use that interface.

Hopefully without needing to do anything in the realm of compiling kernel, cause that is where my half a day long attempt to fix the problem left me.

Debian Hardware :: HDD Not Recognized In BIOS But Recognized Upon Boot

Sep 18, 2014

I have a backup HDD with a different distro for my laptop and i can boot into it via external usb or if swapped into the laptop. This HDD/install in question is debian testing and was working fine, the issue arose suddenly. I was first suspecting a failure of hardware somewhere on the motherboard, but the hdd i was using with an external usb adapter also works when installed into the machine. also, the HDD is recognized once i have booted using the external HDD and distro, but it is not recognized by the bios. so i dunno, my first guess is something became corrupt within the testing install, but i guess its also possible that there is some wrong with the HDD but thats not immediately apparent as all the data is still accessible.

Should also note that the HDD with testing on it is also recognized when connected via the external usb adapter, while booted from alternative distro/HDD.

Also. just tried this, but i can get the testing HDD/disto to boot if connected externally. it was going pretty quick, but there i did catch a line about a corrupt filesystem. any commands to run to see what might be going on?? log files to look at?

Ubuntu :: Sd Card Not Recognized - How To Make It Recognized

Jun 2, 2010

I just installed Ubuntu 11.04. The drive was formatted when I installed so it's 100% Ubuntu. The only major problem I have encountered is that Ubuntu will not recognize my SD cards. I really need to access these cards, all my film footage is on there. I think the internal SD card reader (If such a thing exists) would have been deleted during the installation process. I am a greenthumb to Ubuntu and have never used it before so I am rather stuck...

Ubuntu :: Alt+tab Not Recognized ?

Aug 16, 2010

I'm using Ubuntu with GNOME and alt+tab for switching windows does not work for me. I checked the system prefs & the keyboard shortcut was correct set.

I even tried changing the key to something else (that doesn't contain alt). It didn't work either. It appears as if the manager didn't recognize the shortcut & the key strokes were passed through to the current application. Rebooting didn't help either. Note that I can do alt+f5, alt+space. alt+f2 didn't work though.
