Ubuntu Installation :: Writing SBM File To Floppy With Ntrawrite?
Oct 24, 2010
i am trying to create a floppy boot disk as my computer doesnt support booting from cd. I have downloaded ntrawrite and placed it in a file with the sbm file and followed these instructions [URL] which i found here.
when i type in the command i get the response "ntawrite is not recognised as an internal or external command"
Is the problem that im not opening the cmd in the right directory? I dont know how to change this.
When trying to conigure via nvidia-setting using root (sudo) and then saving to config file I get the ' Unable to open X config file '/etc/X11/xorg.conf' for writing.' in a message box - below is what i get on terminal:
Code: Traceback (most recent call last): File "/usr/share/screen-resolution-extra/nvidia-polkit.py", line 75, in <module> operation_status = main(options) File "/usr/share/screen-resolution-extra/nvidia-polkit.py", line 51, in main
Is there something weird about the FLOPPY DRIVE on F12? Nothing associated with it works & I can't get an icon for it. Also the FLOPPY FORMATTER no longer works. (mine is an internal drive)- I had some really miner quirks with it in 10 but it worked. I had some workaround launchers that I used until an upgrade semi-fixed it. (It would give a false error that it couldn't run but did. I just ignored it.)
I tried to edit FSTAB to cure a problem of my BACKUP drive showing up twice*** so while I was in there I added the stuff for the floppy & it still doesn't work. If I try to mount it manually, I get the error that /dev/fd0 doesn't exist.I tried to find some info on it & it SEEMS that there MAY be a bug but I'm not sure as the info is a bit confusing as to just what version & such they are talking about. And there was also the problem that all the stuff seemed to be OLD or not related to my problem.I why I quite hacking at my system, is that all my workaround launchers & the formatter say that there are GNOME things missing & they can't run. So I figure that there is something missing or screwy already & that I'd better ask BEFORE I make things worse or actually break something.With the fact that floppies are about gone, it's getting to be not that big of a deal but I still find myself having to use them for repair purposes (albeit, not as much) & it gets to be a bit of a pain to fire up M$ just to do something like this.
*** It appears that the one in FSTAB was the one I needed, so where would the OTHER one be so I can get rid of it? Or at least make it auto mount.
I am having a Promise TX4650 RAID controller & trying to create a driver floppy for installing the drivers. Also am using RHEL 5, I can create the driver floppy, but when I type "mount /dev/fd0 /media/floppy" I get error: "mount: mount point /media/floppy does not exist".Can I get the files in a format other than the ext2 floppy image, so that we do not need to use a floppy drive?There is a readme file inside the driver archive & you can use that as a reference.
error message:Unable to scan Floppy Drive for media changes Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.
I am running Intrepid Ibex 64-bit, and I have recently ripped a cd with EAC on one of my windows boxes, and it produced a cue sheet and one single wave file for the entire cd. My question is this, is it possible to take the wave file, burn an ISO image that acts exactly like the original cd? In other words, take the single wave file, using the cue sheet splitting it back into it's individual tracks, and then reading the subsequent ISO image from a program like Sound Juicer, so it can write all the metadata and convert it with my own preferences. I know this is a very strange predicament, but it's one that would save me a world of hassle.
I've combed the prior posts for an answer but cannot seem to find one that fits.I have a half dozen imation super disks, 120 mb. I would really like to use them occasionally.I can't seem to format them to ext because of a permission issue. But I somehow think it is not a user permission problem but a disk issue.I have already done:
Code: chown root:floppy /dev/fd0 && chmod 660 /dev/fd0 && adduser <username> floppy checked to see that I was properly added as an user but when I tried:
Is it possible to forbid that more then one user open the same file in rw mode? In windows when you open a file that another user is using, there's ad advise and you have to open it in read only mode
I installed ubuntu 10.04 desktop edition on 3 pc (there is not a server-client architecture). I installed samba.(and smbfs)
put the strings: [name] comment = ... path = /... guest ok = yes read only = no create mask = 0777 directory mask =0777
Computers that access to that directory do (on boot, with root privileges) mount -t smbfs -o username="user",password="pass" //192.168.0.12/name /mnt/cartelladimontaggio
But if two users access to the same file, both are authorized writing on it! So changes made by one are lost when the other save.
I am trying to write into a single log file from 3 different applications in C. In one of the applications I am forking out 5 instances. I would like to know what is the best way to open and close the log file in which i want to write from these applications. Should I open and close it at the start and end of each application or is it ok performance wise if i open and close it inside the log function which will be called for every write.
I'm looking for a way to make a bootable floppy that has drdflash.img, my flash utility and my bios file on it for a bios recovery disk. This is on a board that has a failed bios, so everything is pretty much dead (except for the humble floppy drive). I don't have a screen to work with so this floppy needs to be able to run the utility and automatically flash the chip for me. I've heard this is possible, but am unable to find clear instructions on how to do any of this. I know the basics of it is to copy the bios file and flash utility to a floppy along with a bootdisk that will run these things (sometimes the .bat file needs to be modified in order to do this automatically). So I've downloaded drdflash but it came as a .img and I don't think it can be 'just' copied to disk. I came across the 'dd' command but have also heard its nicknamed 'data destroyer' or words to that effect.
I recently upgraded my file/media server to Fedora 11. After doing so, I can no longer copy large files to the server. The files begin to transfer, but typically after about 1gb of the file has transferred, the transfer stalls and ultimately fails with the message:
"Error writing to file: Input/output error"
I've run out of ideas as to what could cause this problem. I have tried the following:
1. Different NFS versions: NFS3 and NFS4 2. Tried copying the files to different physical drives on the server. 3. Tried copying the files from different physical drives on the client. 4. Tried different rsize and wsize block sizes when mounting the NFS share 5. Tried copying the files via a different protocol. SSH in this case. The file transfers are always successful when I use SSH.
Regardless of what I do, the result is the same. The file transfers always fail after approximately 1gb.
Some other notes.
1. Both the client and the server are running Fedora 11 kernel 2.6.29.5-191.fc11.x86_64
I am out of ideas. Has anyone else experienced something similar?
so this makes acsv file with one column. I want to run it again but rather than outputing to a new csv i want to add it to this one as the next column. For this example there will be 100 rows per column.
the 1st one will make the file
[grassGIS code]> /home/gary/AVE_monte_carlo/rstats_AVE.csv add ',' after each value the next one [grassGIS code] open file /home/gary/AVE_monte_carlo/rstats_AVE.csv
My computer doesn't support booting from a cd or a usb stick. I managed to install ubuntu (10.04) by using the utility program that came with the live cd. With it I was able to boot from cd and use the live cd., there still seems to be some leftover files of windows in the hard drive where I installed ubuntu. So my question is, how can I reinstall ubuntu so that it will format the whole drive. Is there perhaps a similar utility program for ubuntu that lets me boot from a live cd or can I do the reinstallation just using the already installed ubuntu?
Is it possible to write ksh script in the spec file? The target is after I perform rpm -i my_rpm.rpm According to the spec file, ksh script will do some installation & configuration. For example run other script and edit some files.
I have custom software that writes to a sensitive large file when the user does something. I would like to make backup copies of The file that gets written to, but if I make a gzip of the file at the same time someone is changing something, it will corrupt the backup because some of the data will be missing, as its backed up during being written to.
a) Is there a way to detect if a file is currently being accessed/written to? That way if its currently being accessed, I can just make the script wait until its done and then finally back it up.
b) Instead of backing up the large file while it has potential to get written to, would it be better to make a copy of the file first, then gzip the copy? This idea comes from the fact that gzipping the original takes 5-10 seconds, whereas making a copy only takes 1-2 seconds. The less time, the less chance of corruption.
c) Is there anyway to freeze a program or a file to stop it from being written to for an amount of time?
With a, b, and c together. The best solution I have to my problem would be a script that first detects rather the file is being accessed. If not, it would then freeze the file/program and then make a quick copy of it. Once the copy is created, it will unfreeze the original file/program and then go about gzipping the copy.
I have 3 c files(one of them forks out 5 instances) all writing to one log file. Now to avoid the confusion of opening and closing in each application or instance and running into a situation of not having closed a file I decided to open and close the log file inside the log function for each write.
So what I do currently is fopen, flock, fwrite, unlock, fclose for each write. All the log messages from all the files get written fine and there are no errors but I see a performance hit. The applications talk to each other using SHM(shared memory). So when I try to set a timer and check number of messages lets say I get X messages. Each time I remove or add a log call the number of messages changes. When it is a 1 sec or 5 sec timer it doesnt make a very big diff..few hundreds but when I check it over a longer period..every log call added decreases 1000 messages in count. So I want to know what is an efficient way of implementing the custom log across the application.

Unfortunately I have to use Win NT 4.0 everyday and in fact I am trying to create a system where I have many versions of NT on one disk. My plan is to store them in Linux and create a shell script to over write the first primarly partition which is ntfs. I am trying to install Xubuntu Koala on a logical partition and NT at the start of the disk. Grub is not loading NT well. I want to just use the NT booter and launch Linux from a floppy.
During the install there is an option to write grub to /dev/fd0 but it won't work for me. I tried both fat and ext2 formatted disks and I made sure they were present during the initial boot for auto mounting. I have verified that the floppy drive actually works.
I'm trying to install Ubuntu Netbook Remix 9.10 on a Compaq Evo N200. The problem is that it doesn't have a CD drive on board, and it only supports booting from USB floppy drives- not USB flash or CD drives. I have access to a flash drive, floppy drive and CD drive, all USB externals. I've tried a couple different floppy boot loaders with little success. I understand that it also supports network boot, so this might be an option. What is the easiest way to get UNR running on this laptop?
In installing XP on the first drive of dual boot system using two drives, it requires during setup (after hitting F6 and S) that I install the SATA drivers using a floppy drive (A). I haven't had the need nor have I used a floppy drive in 5 years. I am not sure the old floppy drive I have works or whether the diskette (the original that came with my Abit NF7-S motherboard) has gone bad. Is there a work around for this? Can one even buy floppy drives or diskettes anymore?
Every time I need to use the floppy drive, I again find it not working.I have reported this problem before, and it has been fixed before, several times.It is broken again.Clicking on the "Floppy Drive" item in Nautilus does not even access the drive.Right clicking and selecting "Detect Media" at least spins the disk, but gives the same non-results regardless of whether there is a disk in the drive.With no disk in the drive this happens:
Code: $ sudo mount /dev/fd0 mount: /dev/fd0 is not a valid block device
I'm using ubuntu 8.10 which is already installed. Recently I have downloaded ISO file of ubuntu 10.04. Is there any way to install that ISO file i've downloaded without writing the ISO file in a CD?
I am trying to read a file character wise and trying to write the same character to another file. In this process, I unable to read and write white spaces successfully to the new file. The script reads the white spaces but while writing the white space is lost. The section of the code, is given below. Please advice how can i read and retain the white space while writing to a new file.
Code:
if [ -s f_test.txt ] && [ -f f_test.txt ]; then echo "File Exists !!" while read -n1 char; do
it is about the program sha1sum to create SHA1-hashes. As you probably know, SHA1-Hashes do have the length 20 byte. So when I just type:
Code: sha1sum myfile
it produces an output of
Code: (some20byte) myfile
just as it should. Now I want to store the 20byte hash in another file, I use this command:
Code: sha1sum myfile | awk "{print $1}" >> myhash
Unfortunately I'm not familiar with awk, but this should cut off the end of the sha1sum output, which is the name of the file again. The problem here is: The newly created file myhash has the size 41 bytes, and printing it out I can see that it is not the original hash (I wrote a little program to print it bytewise).
My program need to monitor the foler to know which file under the folder is being opened/created for writing. I add the folder into watch list using inotify_add_watch, when a file -- say 'AA' -- is created, I'll get the event through read api call. But the inotify_event only have file name 'AA' and a event mask. these parameters can't help me to know how the 'AA' is created/openned. So I have to scan the /proc folder to get to know how is 'AA' created/openned. I don't think this is a efficient way, especially if there are lots of files are openned/created in a short time span.
