I have pen-drive and hexEditor, I made my very simple boot sector and I want to boot it from pendrive. Firstly I have to format it, is setting all bits to 0 on pendrive dangerous? or are there any bits that are reserved and I should not touch them?

i don't understand this, why do you have to mount a usb or cd to use them? its such a hassle, in windows the usb/cd just works, but in linux you have to mount it, why? when ever i shutdown in linux, i am using ubuntu it says my drive didn't unmount on shutdown and it might damage my files?

View 6 Replies View RelatedI'm quite new to linux and I recently (and courageously) upgraded the computer of my work from opensuse 11.0 32bits to opensuse 11.2 64bits.
Well, everything would be quite fine except that I still have some softwares 32 bits that have the 64 bits version available. I know that because, using YaST, I can see by the Installed software section that there are 'choices' of versions for some programs; these versions are 'i586' and 'x86_64', and many of them have the i586 version installed.
So, I wonder if there is some type of auto upgrade all programs which are i586 and have the matching x86_64 avaliable...
Can I install Linux 32 bits on system 64 bits?
For example if I have cpu 64 bits, can I install ubuntu 32 bits?
If yes, all drivers will befor 32 bits, right?
I just create a vm image with 2 CPUs to be used on a one CPU machine. it works great. Now, i am thinking about creating a 64 bits Redhat VM image to be run on my 32 bits machine. Is that possible?

View 3 Replies View RelatedOn a Powerbook G4, I set hdparm to set the filesystem readahead (-a) to the maximum 2048 on boot. This produces a visible increase in performance... But today the hard drive started acting up - first generating I/O errors when trying to access various system binaries, and the second time bringing the desktop to a standstill and emitting loud clunking noises.In both cases the drive worked normally after a reboot... Even so, these are not what I'd consider good signs. However, the computer was working perfectly up until now, so I'm wondering if my tweaking was responsible. Can overly aggressive filesystem readahead settings damage an IDE hard drive?
View 2 Replies View RelatedI've had a look at some similar threads but as I'm very new to linux they're already a bit technical for me. Sorry, this calls for someone with patience. I gather from other threads that disconnecting an external drive without unmounting is a no-no, and this seems to be the likely cause. Now the disk is read only and I'm unable to change any settings through the usual control panel on ubuntu. I'm just not familiar with the terminal instructions. I tried to cut and past a few command lines from other threads but I got some warnings that proceding could damage data. Like this one: WARNING! Running e2fsck on a mounted filesystem may cause SEVERE filesystem damage.

There are three new "k1DZ 1n the Block" for CAD users in Linux :
Bricscad
Ares Commander Edition
Draftsight
there used to be Varicad, which also runs in 64 bits natively, as well as QCad ( 2D only ) and BRLCAD ( more of a solid modeler than a Drafting program ), both built from source. Those new K1dZ out there are awesome, but they only run in 32 bits. My system is Squeeze 64 Bits and has multilib enabled... i can install the *deb, and it complains about architecture, so i use --force.. default install is in /opt... still this asks for some libraruies which i do have for 64bits, but do not exist for 32...
So my questions are :
Should I install these 32 bits libraries to run the application ( mostly issues related to rendering ) they would land in /usr/lib32/...
But naming convention in apt or synaptic would still refer them by the same name as their 64 bits counterparts. How does apt (synaptic ) deals with this?
I find all this to much of an unnatural thing to do to my Squeeze install just to make an app fit and run. So far I can remove the app using synaptic but I am very reticent about installing those 32 bits specific libs required by the app. I already have the ia32-libs metapackage installed.
My laptop has a Realtek 8187b usb wireless card. It was working using ndiswrapper and WinXP driver in Debian Sid (32-bits version). I cannot use rtl8187 module because I just can use it beside the access point. With Windows (XP, Seven) I can go to my bedroom and use wireless, with Debian and rtl8187 module I can't. Ndiswrapper solved this problem...
Yesterday I've installed Debian Sid (64-bits version) and ndiswrapper is not working anymore. I've tried a lot of drivers (XP, XP64, Vista, Vista64, Seven, Seven64). XP64 version crashes the computer and I need to reboot to use Debian again. My access point is a D-LINK 2640t.
I want to know what's different between Fedora 32 bits and 64 bits.
Also, I want to know if I want to run 64 bits of Fedora, what do I need ?

I am trying to build a chroot to have 32bits application on a amd64 arch. but when I try the debootstrap command i get this error that I am unable to get through; here it is: debootstrap --verbose --arch=i386 sid /var/chroot/sid-ia32 I: Retrieving Release E: Invalid Release file, no entry for main/binary-i386/Packages
then i tried this solution: [URL] and i progressed but stopped again at one error: E: can't find checksum for packages file.
I was wondering. Up till now whenever I installed Linux I've either dual booted with Windows off 1 HDD, or installed straight Linux by itself. However, I recently purchased a second HDD for my computer, and was wondering how I could go about installing Debian on the second drive without messing with the windows drive? Right now I have Windows 7 installed on my 1TB drive, and would like to try and install Debian on my second (750GB) drive. Would it be possible to install Debian on the second drive, install grub on that drive's MBR so I could choose between Debian and Win7 without touching the MBR on the 1TB Windows drive?
I'm paranoid about messing up my Seven installation, but really want to be able to load into Debian as well.
I'm running Windows 7 on my desktop (But Ubuntu 9.10 on two laptops), and I have an odd problem.I backed up my system from one HDD to another HDD, and in the process the MBR of the destination drive got fouled up and now sees Windows Vista and Ubuntu (even though I never used anything Ubuntu - I assume the backup program used an ubuntu build).Is there any way No, I know there is. I had the answer once but lost it.HOW do I manually edit my MBR to remove the Ubuntu reference and rename Windows Vista to Windows 7? Please note Ubuntu was never dual booted, let alone installed at all, on the HDD in question.

I have a new lenovo thinkserver hardware. I was configuring my newly installed kernel (slackware 13.1 - kernel 2.6.33.4) maybe to weeks now. I was testing the configuration of the kernel parameters.Suddenly out of the blue my BIOS started to report memory error. I have 6 Fully buffered memories in pairs. Four has no advanced ECC and two supports ECC.It is possible to damage the memory by some wrong kernel configuration???I cannot believe that this is possible but I cannot see any other explanation how can a two weeks old hardware get wrong.
View 6 Replies View RelatedI know now: I overwrited the mbr with a totally wrong one, and I have no backup.So far as I can recall, I had two primary partitions; the first one for xp, and there were several logical volumes for linux in the second primary partition).None of these partitions are found now, grub reports "Error 22" with the wrong mbr.Can the mbr be corrected/recovered somehow, in a way that all of the original partitions show up again?
I think, the partitions themselves are not damaged, since only the mbr was overwritten.
I suppose a fixmbr command from the recovery console of the xp installation CD would fix the mbr and make the xp system in the first primary partition bootable. Am I right? How about the second primary partition; would fixmbr find that too? (Sorry for the silly questions, but I do not want to commit more mistakes, especially irreversible ones.)
I'm attempting to set a label for my Windows partition, but it seems risky. Here's a picture of GParted before I attempt to set a label w/ the drive unmounted (wont let me change label when mounted):
After I set a label, the image goes empty as if it will format if I click 'Apply': My question, is it safe to hit apply or will it wipe my drive, and if so, why? In Windows I can just set a label even with the drive mounted.
since my computer don't support booting from USB, can we set it up in the menu.lst option so it will read?
