Identify a 2 GB Compact Flash card to work with older DynaTem CPU card.

I have an older CPU Dynatem (2004) that uses an on-board CF slot that the CPU starts and runs a Linux OS (RedHat 9).  We use a Lexar 2 GB CF (CF2GB-80-380) card, which currently works very well.

The part of Lexar is none past obsolete, and we try to specify a 2 GB CF card to replace it.  We tried to experiment a Sandisk (Ultra P/N SDCFH - 002G - A11) but the CPU card would fail to read the partition on the device of CF tables,

We contacted the seller, and they explained to us that the card slot is not put in place for DMA transfers, as some of the command-line for DMA are not translated on the CF slot, more precisely, DMA REQ and receipt.

For example, Sandisk makes a CF card that will work natively in PIO mode and ignore the missing command DMA signals?

Thanks for your help.

I just wanted you to know that I found a solution to my problem.

Using the ide of the parameter kernanl = nodma, forces the operating system to not use dma mode when communicating with the device see

from kernel /boot/vmlinuz-2.6.18-4-686 ide = nodma root = / dev/hda1 ro

  • H530s - cannot download pictures from Compact Flash card

    I have a H530S. It has a 7 in 1 card reader, but I have a SanDisk Ultra Compact Flash4GB card that does not fit in the card reader. I also have a USB card reader / writer which I plugged in but nothing happens. It's a CRV900 iVAVA.

    Please can someone tell me how I can download my pictures of this type of card? It is used to keep in my old Dell computer, so it is rather annoying that it now, not so easy. I had assumed that the 7 in 1 card reader super - duper must at least have a slot to my Compact Flash card held in so that it is a common map used in the Canon DSLR cameras.

  • HP LaserJet 4250: Brick HP LaserJet 4250 after firmware update failed. Compact Flash card recovery options?

    While performing an update of firmware via FTP using cURL, the HP LaserJet 4250 I worked has frozen. I had no choice but to cycle the power and hope for the best, but unfortunately it was bricked. The screen no longer lights upward when turned on (although I can hear the internal working mechanisms which is a good sign).

    While doing some research, I read it is possible to buy a 32 MB CompactFlash card with preloaded firmware (http://bit.ly/1BTZGCh), put the jumper pin on the logic board to boot from it and then re-flashing the firmware on the card. Looks like a foolproof solution, but I would like to save my company some money if possible.

    I was wondering if it is possible to use a Type I, 128 MB Compact Flash card I have handy and load the firmware above myself using a USB Compact Flash card reader/writer. Judging by what I read on another post on the forum (http://bit.ly/1GR6nM7), it seems possible to use a Unix/Linux utility such as JJ to clone another job Compact Flash card with preloaded firmware. However, I don't have such a card to clone. What I have is another HP LaserJet 4250 in working condition.

    So that raises the question, is it possible to insert my own blank Compact Flash card in a HP LaserJet 4250 work and copy the firmware the logic board to the map image by using the printer control panel? I guess it would be the only way, if necessary, to get the firmware on the card.

    However, if she is not the only way, is there an easier way to get the firmware on the card? For example, can I just format the card in FAT32 and copy the file to the RFU firmware to it and start the printer from him? Or the use of HP does it's own file system that is not readable on a PC? Also, would it be possible to use dd and simply copy the RFU directly on the card device believed himself (no file system) and boot from that?

    Sorry for the barrage of questions. I tried to find the answers to all these myself, but HP doesn't seem to provide a lot of detailed documentation on works of the firmware via Compact Flash process. I'd be very happy if someone with experience could provide the answers well! Thank you.

    Looks like I'll be solving my own number here haha. So after bit peicing together information from different positions and some experiences, I managed to save my LaserJet bricks!

    To fix a HP LaserJet 4250 bricks, two things are necessary: an of Type I CompactFlash card and other HP LaserJet 4250 work. It's a common printer, chances are you'll find another around the office.

    Here are the steps to fix the printer:

    1. The card CompactFlash Slot 1 (bottom slot) on board the logical work printer. Instructions on how to do so are provided by HP here: http://bit.ly/1NNyIol
    2. (May be optional) Initialize (format) the CompactFlash card by following the instructions on page 327 of the repair of HP LaserJet 4250 (http://bit.ly/1D22T7R)

      (a) turn off the power to the printer.
      (b) turn on the power to the printer and then press and hold the MENU button when begins the memory count.
      (c) continue to hold the button down until all the lights on control panel three printer flashes once and then remain lit. It may take up to 10 seconds.
      (d) press the BACK ARROW button. The display should INITIALIZE the DISK.
      (e) press Select (mark). The printer initializes the hard drive and continues its power on sequence.

    3. Now that the CompactFlash card is formatted, it is time to copy the NAND of the printer to work on the CompactFlash card.

      (a) turn off the power to the printer.
      (b) turn on the power to the printer and then press and hold CANCEL when begins the memory count.


    (c) continue to hold the button down until all the lights on control panel three printer flashes once and then remain lit. It may take up to 10 seconds.
    (d) press the SELECT button (check mark).
    (e) press the MENU button.
    (f) use the arrow to scroll until you see COPY BOOTLOADER IN SLOT2.
    (g) press SELECT, and the cursor should get the word BOOTLOADER. Use the arrows to change this to NAND.
    (e) press SELECT, and the cursor should get the word SLOT2. Use the arrows to change this to SLOT1.
    (f) press SELECT. The copy process must begin, and the status will appear on the screen.
    (g) once the process is complete, turn the printer off and remove the CompactFlash card.
  • Now that we have a working NAND on the CompactFlash card, it's time to restore to our printer masoned. Perform the following steps on the printer of bricks.

    (a) turn off the power to the printer.
    (b) Insert the CompactFlash card into Slot 1.
    (c) set the jumper on the System Board on the arrow to start from the CompactFlash card.
    (d) turn on the power to the printer and then press and hold CANCEL when begins the memory count.
    (e) continue now the button until all the lights on control panel three printer flashes once and then remain lit. It may take up to 10 seconds.
    (f) press SELECT (checkmark).
    (g) press the MENU button.
    (h) use the arrow to scroll until you see COPY BOOTLOADER IN SLOT2.
    (i) press SELECT, and the cursor should get the word BOOTLOADER. Use the arrows to change this to SLOT1.
    (j) press SELECT, and the cursor should get the word SLOT2. Use the arrows to change this to NAND.
    (k) press SELECT. The copy process must begin, and the status will appear on the screen.
    (l) once the process is complete, turn off the printer, remove the CompactFlash card and reposition the jumper to the default position.
    (m) turn on the power to the printer. That's all! Everything should work normally again. No brick no more!

  • UPDATE (07/04/15): IF YOU DO NOT HAVE ANOTHER HP LASERJET 4250

    It turns out that you can just download the firmware on HP website and create an image of it bootable on a CompactFlash card. However, it is not as simple as just copying the firmware image. You should ignore the 633 first bytes of the file of the firmware (at least with the 08.260.1 version), then copy the rest on a CompactFlash card. You can accomplish this by running the following command on Mac OS X or Linux. Download and boot from a live CD of Linux like Ubuntu if necessary.

    DD if = lj4240_4250_4350fw_08.260.1.rfu ibs = 1 skip = 633 of = / dev/disk2

    Replace "lj4240_4250_4350fw_08.260.1.rfu" with the name of the appropriate firmware file and ' / dev/disk2 ' with the appropriate device if necessary.

    If you prefer, a bootable copy of the revision of the 08.260.1 firmware can be downloaded here: http://bit.ly/1FeF3YP

    As you can see in the image below, when opened with a hex editor, image downloaded from HP firmware starts with 1 b 25 31 2d bytes... However, the printer does not include the first part of the file when you start, because there are instructions of PJL and not binary. Bootable image begins at 631 byte (277 hex) highlighted. It may be possible that this address may change in future versions of firmware or for different printers, so here's how to know where to start the startup code. The first occurrence of 00 00 04 24 bytes, is where that starts. In ASCII, it looks to "... $". In this sequence, the 00 first is the beginning of the startup code. Here's another picture, of what should look like a bootable firmware image.

    Non-bootable firmware image, downloaded directly from HP

    Bootable firmware image, extracted of HP download

    For fun, I unpacked it some of the files included in the firmware image, and it turns out that tracks on the printer to LynxOS. Who would have thought?

  • Compact flash card in the atmosphere of the iPad

    A way to download pictures from a compact flash card or directly from my 5 d Mark III to air from my iPad. I know that Apple has a SD card cable. anything for the compact flash?

    Tell your 5 d III to save images on the SD card and use the SD card reader.

    You can optionally use Apple's USB adapter and then connect via the USB cable (in this case any card slot lets you record images.)

  • Back up the old hard drive to the laptop on a Compact Flash card

    Hello:

    I have an old laptop Compaq 1220, works under Windows 95.

    I have a CD drive (read only) and an internal 2 GB drive hard.

    It has a slot for a card-card: the card can contain a Compact Flash (CF) card.

    I also have a HP laptop much more current, which can read/write from/to CF cards,.

    via a CF card recorder/reader, which has a USB conector.

    I would like the files to "Backup" 2 GB HD to the CF card, so that they can transfer to the HP laptop.

    I have to do something other than files (special) "gliding &" of the 1220 Compaq to the CF card?

    If so, please provide details.

    I don't think I need to transfer all the Windows 95 files since they would be worthless for the

    HP laptop running Vista 32 bit Home Premium (or I'm wrong).

    I don't think I need to create an encrypted "image", because I don't want to install it on another machine (with BONE).

    Thank you...

    Hello

    There is no special procedure other than drag / move to copy your Windows 95 computer data files in the card compact flash.

    You will have to copy the files from Windows 95 computer data to compact flash card, then insert the same card compact flash in the Windows Vista-based computer card reader and then transfer the data files.

  • Copying of images from Compact Flash Card Reader on Windows 7 x 64 corrupts some image files.

    When the copy of Canon RAW files produced by a Canon EOS 40 d and Canon's EOS 5DMk2 Canon EOS 7 d a card compact flash on a PC running Windows 7 x 64 a small percentage of the files become corrupt. I tested it with several internal and external USB card reader, with the same results. Always the same images of a set of images on the card are corrupted. On my system with Windows Vista x 32 or Windows 7 x 32 this problem does not occur. If you copy an image corrupted from a machine Windows 7 x 64 one of the x 32 machines always corrupt. But you copy the same image directly from the CF card, it will be corrupted on Windows 7 x 64, but is perfectly fine in a x 32 machines. Is anyone familiar with this problem? No work around? I am a photographer and it is really annoying my workflow.

    This problem has been recreated on the following computers:

    Dell Dimension 9100 Running Windows 7 Profesional x 64
    Dell XPS m1210 Running Windows 7 Enterprise x 64

    This problem does not occur on the following computers:

    Dell Dimension 9100 Running Windows Vista Ultimate x 32
    Reference Dell Inpiron 9100 Running Windows 7 Professional x 32
    Dell XPS m1210 running Windows Vista Enterprise x 32

    Talk about drive you crazy, I can have recently fixed this problem for my PC, but I can't really understand what was the exact solution. In any case if you read my posts above, you'll see that I at least 4 PC running Windows 7 that has this issue. I have two cameras from Canon (40 d, 7 d) that present this problem and 4 compact flash cards (2 for each camera) which show this question. This issue is also never appeared on my other 2 cameras (300 d and 20 d) or on Windows XP or Windows Vista.

    To test this recurring problem, I kept one of my CF cards which was full of RAW files and stopped using it with my cameras. I used images on this card for testing. I copy the images of this map on a PC hard drive then I would like to make a second copy on the hard drive. A copy of the images I would have spotted in Adobe Bridge, the second copy I would consider only with the Canon DPP. Whenever there are images corrupted in the game that I give in Adobe Bridge and no corruption in the game that I would only see with Canon's DPP. I would then use WinMerge to compare one of the images corrupted in Bridge with uncorrupted counterpart. Sometimes the files differed not at all, which indicates that the corruption was in Adobe Bridge preview only. Sometimes there are clearly major differencs between files, which indicates that the corruption was in the file RAW itself.

    I repeated this test again and again on at least 4 computers running Windows 7. It became easy to reproduce and repeatable. The differences between several PC was that different images become corrupt on different PCs. By default on a PC, changing as ACR would affect what images have become corrupt.

    With the above in mind, I would test with clean installs on the PC. With anti-virus turned off. Without any element in windows startup. With different video cards, etc. Nothing has worked. Then on a whim, I bought and installed the Codec Pack FastPictureViewer 2.1R2 (http://www.fastpictureviewer.com/codecs/) on one of my PC Windows 7 x 64. After a reboot, I then ran my standard test above. To my surprise, none of the pictures of the test set has become corrupted. The first time it never happened on Windows 7 for sure.

    Great, I thought. So now if I take this CF card and copy the images on a PC without the Codec Pack, then the images would still become corrupt because with the right Adobe Bridge? Well, bad actually. On my other three PC without the Codec Pack these images now copy the CF card with no to corruption. The new pictures that I take with a camera show also no corruptiopn on any computer with or without the Codec Pack. It's really weird.

    All I can theorize it, is that there is something wrong with some data that has been written for cards CF. In the directory structure or some cache hidden on the CF card somewhere float codec RAW of Canon presents incorrect data, but ACR and the CaptureOne seemed not only to become confused by it, they would actually rewrite the interpretation corrupted in the file RAW itself. It's curious because the display of hidden files and protected system files do show all files on the CF card other than RAW images. The only thing that's changed on the map, it's that when I opened it upward in the preview vignettes explore now show instead of the generic Adobe icons for CR2 files. On the PC without the Codec Pack, the generic icons show yet, but very good copy the files. Whatever it either, with the Codec Pack to build miniature previews on PC it sets whatever the problem of all the PC have had reading the data off the card.

    I can't explain it. I reformatted the CF card camera and on my two PCs and doesn't seem to make a difference. But by the mere fact to have a codec generate a thumbnail preview, it seems to have 'fixed' regardless of the question. Very confusing. For the last three days, I tried to recreate the problem of corruption and simply cannot. If she resurfaced once again, I will post it here, but for now it seems that this problem is solved?

  • What Flash Speedlite will work with my Canon Rebel EOS T3 1100 D?

    Hi, I'm new to the era of digital and older than 55 years.  My husband bought me a Canon Rebel EOS T3 1100 D in July.   (I fought the "technological" upgrade until my old film camera Canon quit on me).  I took pictures since 1966, so I'm not new to photograph, just for our technological advances.

    I would be very grateful if someone could help me with which Flash Speedlite will work with my Canon Rebel T3 D 1100 camera specific.

    I thank very you much for your time.

    I just got my 430EX II that I bought for use with my Rebel T2i. The main reason I bought the Canon product was... using Canon products, I have never had a failure or a bad experience of 60 years. I use the LL 430EX for a few days and I'm very happy with the results. Much, much better than the built-in flash. It is on sale now with free shipping of Fed X. It is hard to beat.

    Good luck with your new camera.

  • 5 d Mark III to access the (compact flash) card error

    I just got a Canon 5 d mark III and having problems with it access to the card compact flash. This has happened on 4 different cards all gig Lexar professional 32 X 1000. I have a Canon 7 d and the cards work fine in it. All the cards have been formatted by the 5 d Mark III before using. It seems sometimes they work and other times it won't.

    Hi cuda719!

    Thanks for posting.

    It is certainly unusual, but not after testing all the cards on the market, it is difficult to ensure that all the same cards will work with all cameras.  To isolate the problem to the cards or the camera, try to use another card which is not identical to the 4, that you used.  If the camera is still the error with the spare card, it must be repaired.

    To start the repair process, you need to fill out a service request on our Web site.
