  • How do boot sectors and multiple drives works?

    - by GiH
    I don't fully understand the concept of a boot sector, I was hoping someone could clear this up for me. If you have two hard drives, with an OS installed on each, does each drive have its own boot sector? Does each drive need an MBR partition? I've got Linux and Windows on two separate drives. I've had issues when installing Linux and grub, and now I've finally decided to use the Windows bootloader to start up. Would Windows have gotten rid of grub when i used /fixmbr or does it stay there on the boot sector of the other drive?

  • Performance degrades for more than 2 threads on Xeon X5355

    - by zoolii
    Hi All, I am writing an application using boost threads and using boost barriers to synchronize the threads. I have two machines to test the application. Machine 1 is a core2 duo (T8300) cpu machine (windows XP professional - 4GB RAM) where I am getting following performance figures : Number of threads :1 , TPS :21 Number of threads :2 , TPS :35 (66 % improvement) further increase in number of threads decreases the TPS but that is understandable as the machine has only two cores. Machine 2 is a 2 quad core ( Xeon X5355) cpu machine (windows 2003 server with 4GB RAM) and has 8 effective cores. Number of threads :1 , TPS :21 Number of threads :2 , TPS :27 (28 % improvement) Number of threads :4 , TPS :25 Number of threads :8 , TPS :24 As you can see, performance is degrading after 2 threads (though it has 8 cores). If the program has some bottle neck , then for 2 thread also it should have degraded. Any idea? , Explanations ? , Does the OS has some role in performance ? - It seems like the Core2duo (2.4GHz) scales better than Xeon X5355 (2.66GHz) though it has better clock speed. Thank you -Zoolii

  • Quad channel memory and compatibility

    - by balteo
    My motherboard has quad channel memory compatibility. There are 8 memory slots in all: 4 slots are black the other 4 slots are white. I currently have 4 memory modules of 1 GB each in the 4 white slots. That leaves me with 4 free memory slots. My question is: can I put 4 memory modules of 2 GB each in the 4 remaining slots or do I have to use modules of 1 GB all over? FYI here is the output of lshw: alpha description: Ordinateur Tour produit: Precision WorkStation 690 *-cpu:0 description: CPU produit: Intel(R) Xeon(R) CPU X5355 @ 2.66GHz *-memory description: Mémoire Système identifiant matériel: 1000 emplacement: Carte mère taille: 4GiB *-bank:0 description: FB-DIMM DDR2 FB-DIMM Synchrone 667 MHz (1,5 ns) produit: HYMP512F72CP8N3-Y5 fabriquant: Hynix Semiconductor (Hyundai Electronics) identifiant matériel: 0 numéro de série: 56737501 emplacement: DIMM 1 taille: 1GiB bits: 64 bits horloge: 667MHz (1.5ns) *-bank:1 description: FB-DIMM DDR2 FB-DIMM Synchrone 667 MHz (1,5 ns) produit: HYMP512F72CP8N3-Y5 fabriquant: Hynix Semiconductor (Hyundai Electronics) identifiant matériel: 1 numéro de série: 48115124 emplacement: DIMM 2 taille: 1GiB bits: 64 bits horloge: 667MHz (1.5ns) *-bank:2 description: FB-DIMM DDR2 FB-DIMM Synchrone 667 MHz (1,5 ns) produit: HYMP512F72CP8N3-Y5 fabriquant: Hynix Semiconductor (Hyundai Electronics) identifiant matériel: 2 numéro de série: 48115523 emplacement: DIMM 3 taille: 1GiB bits: 64 bits horloge: 667MHz (1.5ns) *-bank:3 description: FB-DIMM DDR2 FB-DIMM Synchrone 667 MHz (1,5 ns) produit: HYMP512F72CP8N3-Y5 fabriquant: Hynix Semiconductor (Hyundai Electronics) identifiant matériel: 3 numéro de série: 48115424 emplacement: DIMM 4 taille: 1GiB bits: 64 bits horloge: 667MHz (1.5ns) *-bank:4 description: FB-DIMM DDR2 FB-DIMM Synchrone 667 MHz (1,5 ns) [vide] fabriquant: FFFFFFFFFFFF identifiant matériel: 4 numéro de série: FFFFFFFF emplacement: DIMM 5 bits: 64 bits horloge: 667MHz (1.5ns) *-bank:5 description: FB-DIMM DDR2 FB-DIMM Synchrone 667 MHz (1,5 ns) [vide] fabriquant: FFFFFFFFFFFF identifiant matériel: 5 numéro de série: FFFFFFFF emplacement: DIMM 6 bits: 64 bits horloge: 667MHz (1.5ns) *-bank:6 description: FB-DIMM DDR2 FB-DIMM Synchrone 667 MHz (1,5 ns) [vide] fabriquant: FFFFFFFFFFFF identifiant matériel: 6 numéro de série: FFFFFFFF emplacement: DIMM 7 bits: 64 bits horloge: 667MHz (1.5ns) *-bank:7 description: FB-DIMM DDR2 FB-DIMM Synchrone 667 MHz (1,5 ns) [vide] fabriquant: FFFFFFFFFFFF identifiant matériel: 7 numéro de série: FFFFFFFF emplacement: DIMM 8 bits: 64 bits horloge: 667MHz (1.5ns) *-pci:0 description: Host bridge produit: 5000X Chipset Memory Controller Hub fabriquant: Intel Corporation identifiant matériel: 100 information bus: pci@0000:00:00.0 version: 12 bits: 32 bits horloge: 33MHz

  • how to broadcast a PXE server like Trinity Rescue Kit

    - by Larry G. Wapnitsky
    I would like to set up a portable PXE server for diagnostic purposes. The issue is that I won't always have access to the DHCP server, or the router itself (sometimes a home router) doesn't have an easily accessible place to set the servername/file for broadcast. I know that Trinity Rescue Kit is able to broadcast its PXE server without its own DHCP server. Can anyone point me in the direction to set this up on my own (without Trinity)? Thanks.

  • How to get Windows Server 2008 VM to use multiple cores

    - by David Fraser
    I have a Windows Server 2008 machine running in VirtualBox. On initial installation, only one processor was made available, but now I want to run it as a multiprocessor machine. I have made all four cores available in the VirtualBox settings (as well as enabling VT-x/AMD-V and Nested Paging), but Task Manager still only shows one CPU. However, the four CPU cores are visible in Device Manager under Processors. In the event log on startup, I can see the following relevant events: EventLog.6009 Microsoft (R) Windows (R) 6.00.6002 Service Pack 2 Multiprocessor Free Kernel-Processor-Power.4 Processor 0 exposes the following: 1 idle state(s), 0 performance state(s), 0 throttle state(s) Kernel-Processor-Power.4 Processor 255 exposes the following: 0 idle state(s), 0 performance state(s), 0 throttle state(s) Kernel-Processor-Power.4 Processor 255 exposes the following: 0 idle state(s), 0 performance state(s), 0 throttle state(s) Kernel-Processor-Power.4 Processor 255 exposes the following: 0 idle state(s), 0 performance state(s), 0 throttle state(s) How can I make this system actually boot up as a multiprocessor machine?

  • Two people using the same computer at the same time remotely!

    - by Mani
    We have two computer in office and two people. My computer is much more faster than another computer. Is it possible my colleague connect to my computer remotely and work by my computer? Using "Remote Desktop" in Windows only one user can log into computer. So when he connect remotely, my user logged off. Is there a tool which can help in this case? I already knew VNC (RealVNC) But it's not helping because when a user connect to my computer, he see exactly my desktop, not his own user desktop.

  • Wordpress multisite and redirect

    - by Dr I
    I come to you because I'm facing a really strange effect on my hosting. I currently manage a server contening a NGINX/PHP-CGI and a wordpress multisite in it. My sites are created using subsite.domaine.tld, for now, my three subsites are correctly accessibles through the url: subsite.domain.tld. My goal is to allow my subsite on the host domain to be access through their respective unique domain. For exemple: www.domainA.com would redirect to subsite1.host.domain.tld. If I do that using the following setting on the domainA Public DNS: www 10800 IN CNAME subsite1.host.domain.tld. When I try to access www.domainA.com I don't go to subsite1.host.domain.tld but instead I'm redirect to the Wordpress ROOT site where I create my Network (host.domain.tld). Is there a trick to deal with?

  • How to install Ubuntu, Windows XP and Windows 7 from scratch as triple-boot system

    - by simon
    I'm currently running Windows XP, but have ordered Windows 7. I want to keep Windows XP on a separate partition, and install Ubuntu as well. In which order should I install the OSs, and is there anything differing from an ordinary single-system install I should keep in mind? For example, does the order of partition make any difference? If I want to have the system drive as "C:" drive in both Win XP and Win 7, what should I do?

  • GRUB Error after Deleting Linux Partition

    - by Nironan12
    I was dual-booting with Windows 7 and Windows Vista each taking up half of my hard drive. In Windows 7 I used Easeus Partition Manager to shrink my Windows 7 volume 8GB. On the unallocated space, I installed Linux Mint 8 RC1. After a little bit of playing around with it, I booted in Windows 7, used EPM again and deleted the 8GB Linux partition. I then extended Windows 7 on the 8GB. After restarting my computer, all I get is a black screen and this: GRUB loading. error: no such partition grub rescue> I do not have a Windows 7 disk nor does my computer come with Startup Repair. What do I do?

  • How to stop OS X from switching input method (keyboard layout) automatically?

    - by adolf garlic
    After using the wireless keyboard that comes with the iMac, I have switched to a MS Ergo Natural 4000 one. Surprisingly I had to install extra software as OS X could not work out which keyboard I had. After which I went into sys prefs and set the main input method to be "British - Microsoft" first and "Swiss German" second (what the wireless keyboard is), on the "input sources" tab: However... OS X keeps resetting my input method back to Swiss German which is driving me bananas. I have the flag thingy top right so I can see when this changes. N.B. I have "input source options" set to "use the same one in all documents" which I am assuming means keep the language the same for anything running. It also flips back on the login page. Does anyone know how to fix this?

  • Windows 7 won't boot from any bootloader except for Windows Boot Manager after partition resize

    - by user2468327
    I have a triple boot system on a single SSD: OSX, Windows 7, and Ubuntu. I use Chimera (basically another version of Chameleon) as my bootloader. Usually I can boot all 3 OSs without any issue, but after using GParted to make my Ubuntu partition 2 Gigs larger, Windows 7 throws me an error when trying to boot to it from either Chimera or Grub. The error is consistently: `0xc000000e can't find \Boot\BCD" (slightly paraphrased). However, I can still get into Windows by selecting Windows Boot Manager from the boot options in my BIOS. I've already tried several known fixes for similar issues, including bootrec /rebuildbcd (and variations), and BootRec.exe/fixMBR + BootRec.exe/fixBoot. I've also tried Chkdsk. At best this has made it so Windows 7 boots on its own by default (making me have to reinstall Chimera and change back my boot settings in the BIOS). At worst this made it so Windows won't boot period. Now I'm back full circle where I started. A detail that might be useful is that bootrec /rebuildbcd says that the number of found Windows installations is 0. I'm fairly certain that I don't have a hybrid MBR. Mainly because I have a UEFI BIOS, and with that, it appears each OS can support a GPT. So it would kind of pointless to have and deal with. I may be wrong though, I couldn't find any way of finding out for sure online. However, I know for sure that the version of Windows I have installed is the UEFI version, as well as every partition tool I've used to look at my boot drive tells me it's GPT. How do I get it back so I can boot Windows 7 through another bootloader so I don't have to manually select it in the BIOS? Preferably without a reinstall.

  • How can I dual install Ubuntu 10.4 in a Mac Mini with 10.4.11?

    - by Marco Mariani
    I'd like to power-up my aging Mac Mini (1.5GHz Core Solo, 1GB RAM, Tiger 10.4.11) by installing a shiny Ubuntu alongside the current OS. After all, I use Ubuntu for everything save for cleaning my teeth. Since it's my first and only Mac and I have next to no experience with the OS (having used it basically as a media player) I am a little concerned about rEFIt, ELILO, Boot Camp and the fact that it's basically a 4.5 years old unsupported machine and I might get asleep reinstalling everything several times. I've used the live desktop-i386 CD and everything works. I tried with an external USB drive instead of a CD but couldn't make it boot. As for installing Ubuntu, the howtos I've found give several alternatives depending on the model, the OSX version, etc.. but they usually talk about newer machines. Which howto should I follow to repartition, and boot thereafter? Thanks

  • Does Windows 7 Home Premium support Dual Core Processors?

    - by nicon
    I'm looking to buy a new laptop (the new studio 14 from Dell). The processor for this laptop is an Intel Core i5-520M. Think link http://reviews.cnet.com/8301-31012_7-10379487-10355804.html says that it supports only 1 CPU. Also Dell recommend the Professionnal version even tough Home Premium is the default choice. So I'm a little confuse as does Windows 7 Home Premium support Dual Core Processors ?

  • Can't boot into Linux partition after installation

    - by Otto
    I just installed Ubuntu. I created a partition in MacOSx using Disk utility, then deleted the partition and installed Ubuntu on the free space created. After the installation, Ubuntu said it would reboot. I hang on shutdown (which is normal, as google told me), so I used the power button to turn the MacBook off. Now I want to boot into Ubuntu. Pressing option/alt on startup only shows me the MacOSx and Windows partition. Also, the Linux partition isn't showing up on my MacOSx desktop. And in Disk Utility, I can see 3 grayed out partitions: "disk0s4", "disk0s5" and "Linux Swap". What can I do to boot into Ubuntu without losing my other partitions? Thank you for your help.

  • How to configure machines in a public subnet with two gateways?

    - by Shtééf
    We have a single public /24 subnet, with a BGP router as the primary gateway. Now I'm interested in configuring a second router for redundancy. How do I deal with multiple gateways on the servers in our public subnet? I found some other questions related to multiple gateways that seem to deal with NAT set-ups. In my situation, the servers all have public routed IP-addresses. So from what I can tell, it doesn't really matter which route incoming or outgoing packets take. But I figure the servers need some way of telling when one of the gateways is down, and route around it? Is this accomplished with protocols such as OSPF? And do I need to deploy this on all my servers?
