Any idea?

Interesting... perhaps this is handled some how by mkinitcpio?  I didn't see anything obvious in the hooks section.
progandy wrote:Edit: You can download the microcode data here: https://downloadcenter.intel.com/Search … crocode%22
This gives the same file that [extra]/intel-ucode uses, but neither the source nor the package provides "GenuineIntel.bin" mentioned in the document.
EDIT: If the info contained in the blog post you referenced is indeed accurate, I fail to see what value the intel-ucore packages provides at all.  In other words, it loads the updates after the kernel has already disabled the features the updates are fixing.  Seems as though either:
1) The package provides superfluous files.
2) It needs to generate a modified initrc image as described in the early-microcode.txt file you referenced.
3) We are wrong and the package does indeed provide a solution.

  • How can i fix "invalid processor microcode update" i have a compaq dc7100 cmt

    My m/c is a HP Compaq dc7100 CMT(DX438AV).
     I've replaced the 2.8 processor with a P4 HT 3.4ghz 1M/800 SL7PY , during start-up it gives the message "missing or invalid processor microcode update"
     My motherboard is HP 0968h . My Bios is...  Version : 786C1 v01.05
    I looked at specs for the board and i think it supports this chip, can anyone help fix this problem
    Thanks..
    This question was solved.

    Hi:
    Now that you installed the latest microcode update, may I recommend you install the Pentium 4 650 3.4 GHz?
    That processor has double the L2 cache as the one you installed, and you can run a 64 bit operating system on it.
    If you have the CMT, you have a pretty wide assortment of video cards you can install so you can run all of the features of Windows 7.  The onboard GMA 900 video won't run Aero. Just keep within the power supply limit of 345W
    I have W7 x64 on my dc7100 CMT and an ASUS nVidia 8400GS 512 MB fanless video card in mine, and everything works great. Recommended P/S is 300W for the card so I was fine.
    The P4 650 is pretty reasonable on eBay. That is where I got mine.

  • Solaris 10 AMD Athlon Opteron BIOS microcode patch

    I've recently installed Solaris 10 on AMD Opteron machine, AMD64
    On boot, I receive a message "BIOS microcode patch not found...erratum 109" or something to that effect.
    this is followed by a bunch of "not enough space" comments.
    I've tried to find such a patch without success. Clearly, this points out my lack of knowledge. Perhaps someone can provide advice? AMD said "call Sun"

    I went back and did a reinstall of OS. I then downloaded and installed all the patches associated with the machine W1100Z. This has made this operational but issues remain. I decided to download the latest supplement.iso (2.5) and install the newer BIOS. The supplement.iso size is 427.89 MB. Unfortunately, at 427.11 MB I receive an error "not enough memory in the folder". I get the same result regardless of the target directory. I do suspect the installing the new boot image will work but the problem of how to get in on the machine remains.
    I apologize for the delayed response but I only have so much time. I have considered the purchase of a new machine would be a good choice, with OS already installed, but this one is autographed by James Goslin. An operating machine certainly would be a great SUN advertisement in my office. Plus, the tanking markets have significantly reduced my upgrade capability.
    You are probably correct though. Finding the disks may be a problem especially cdrom.
    cd c:\cdrom
    ls -l

    Hello, 
    i've been reading and reading this post for a several times and i'm not sure will this work on my PC so i must ask, how to fix "1801-Microcode Update Error" in HP Compaq dc7700p Convertible Minitower i've upgraded it with E7200 instead of the original E6300
    here's Product Number: p/n RN120ET#UUZ
    I'm able to boot up and start windows i don't know is it working normaly or not, i'm just annoyed with the boot message: 
    Please HELP and Thank You in advance !!!
    This question was solved.
    View Solution.

    Hi:
    You will need to update the BIOS to its latest version to get rid of the microcode error, and the processor will only run at half the FSB speed because the BIOS update was not written to make the E7xxx processors work correctly.
    You will need to run this software each time you get into windows and change the multiplier to the max.
    Or you can run that batch file listed on the below webpage for it to run automatically.
    http://crystalmark.info/software/CrystalCPUID/index-e.html
    If I were you, I would just install a Conroe E6700 and have a problem-free upgrade.
    You will need to use the DOS based flash because I don't think there is a BIOS update written for W7.

  • Xw6200 1801 microcode update error

     Hi I have recently upgraded my xw6200 workstation cpu from 2 x intel xeon 2.8 ghz to 2 x inel xeon 3.6 ghz. the problem is when i but up my pc i get a error "1801 microcode update error" and give me the option to boot by pressing f1 and the it boots up no problem apart from the fans are a lot noisier. is there a way to solve this error every time i boot up. its not a massive problem as windows runs fine after i press F1 but any help would be appreciated thanks.

    Unfortunately, the latest  version of the installed BIOS version is as good as it gets.
    The BIOS family 786B7, which your BIOS is a member of,  was last updated in 2006.
    Unless a microcode update can be found through Windows update or at Intel for the installed operating system, this may be an issue that I am unable to help you resolve.
    Normally a BIOS update is the answer, but no more exist.

  • Can not access BIOS after update BIOS

    Can not access BIOS after update X220 BIOS to version 1.19

    Ask google and try anyway but not work
    - Press ThinkVantage, Press F1, Press Fn+F1
    - Power off, unplug AC, unplug battery, wait 15 miniute, try all again
    - Try to update BIOS again

    That is really weird.
    When you are in Windows, can you test and see if the F1 key is working? If it is working. Shut down the laptop then boot it back up. At the Thinkpad screen, keep spamming the F1 key and see if you are able to boot into BIOS.

  • How to fix "1801-Microcode Update Error" in HP Compaq dc7800 Convertible Minitower

    I have Intel Core 2 Duo @ 2.93 Ghz. My operating system is Windows 7 Ultimate x64. 
    This question was solved.
    View Solution.

    Hi:
    The E7500 processor is not supported in the dc7800, which is why you are getting the microcode error.
    Below is the list of supported processors.
    Intel Core 2 Duo Processors:
    Intel Core 2 Duo E4500 Processor (2.20-GHz, 2 MB L2 cache, 800-MHz FSB)
    Intel Core 2 Duo E4600 Processor (2.40-GHz, 2 MB L2 cache, 800-MHz FSB)
    Intel Core 2 Duo E4700 Processor (2.6-GHz, 2 MB L2 cache, 800-MHz FSB)
    Intel Core 2 Duo E6550 Processor (2.33-GHz, 4 MB L2 cache, 1333-MHz FSB)
    Intel Core 2 Duo E6750 Processor (2.66-GHz, 4 MB L2 cache, 1333-MHz FSB)
    Intel Core 2 Duo E6850 Processor (3.0-GHz, 4 MB L2 cache, 1333-MHz FSB)
    Intel Core 2 Duo E7200 Processor (2.53 GHz, 3 MB L2 cache, 1066 MHz FSB)
    Intel Core 2 Duo E7300 Processor (2.66 GHz, 3MB L2 cache, 1066 MHz FSB)
    Intel Core 2 Duo E8200 Processor (2.66-GHz, 6 MB L2 cache, 1333-MHz FSB)
    Intel Core 2 Duo E8300 Processor (2.83-GHz, 6 MB L2 cache, 1333-MHz FSB)
    Intel Core 2 Duo E8400 Processor (3.00-GHz, 6 MB L2 cache, 1333-MHz FSB)
    Intel Core 2 Duo E8500 Processor (3.16-GHz, 6 MB L2 cache, 1333-MHz FSB)
    Inter Core 2 Duo E8600 Processor (3.33-GHz, 6 MB L2 Cache, 1333-MHz FSB)
    As a long shot, you can try installing the latest microcode update. You need to use a bootable USB flash drive with dos files so you can run the flashbin.exe command after you copy the microcode update files to your bootable flash drive.
    I can't get to the dc7800 support site. When you can, select the microcode update download from 2010  v1.14
    If you are unfamiliar with how to make a flash drive bootable, here is a good "how to" article with the files you need.

  • PSE Not showing camera raw update 8.8

    My PSE13 is saying that camera raw is up to date at 8.7 but it will still not read my NEF Files.. I saw camera raw 8.8 is available but my PSE is not showing an update available so how do I manually update my Camera Raw?

    Perhaps that is your experience, MBP, at a particular point in time and/or on a particular platform for version of PSE13, but for me on Windows 7 and Windows 8, with PSE 13.1 & ACR 8.7.1 installed, there still is no update found when checking from Help / Updates in the PSE 13 Editor.  I have also downloaded and installed the Camera RAW 8.8 installer from the Adobe HelpX page, and that installer installs ACR 8.8 for PS-CS6 and PS-CC but no PSE13--I have all three on my system.  I can manually copy the plug-in from the PS folder to the PSE folder but that's not something the updater is doing on its own.
    For someone who has some computer savvy, and is running Windows, at least, you can download the ACR 8.8 installer EXE, rename it to have a .zip extension, open it with 7zip (not Windows native compressed folder handling, or WinRAR) and unzip the contents to somewhere, then look for the Camera Raw.8bi file, and copy that over the top of the PSE13 file of the same name.  There are two Camera Raw.8bi files.  The one under $SHELL[70] is the same size as in my PS-CC so I assume that is the 64-bit one.  There is another one under $MUSIC that is slightly smaller so maybe that is the 32-bit one but the folder structure also says CC so I'm not sure.
    The installer is here:
    Camera Raw plug-in installer
    Besides the .8bi plug-in there are also new camera profiles.  Those can be more easily installed by installing the DNG Converter 8.8 available from the Adobe Updates page:  http://www.adobe.com/downloads/updates/

    I am aware that Xen can do some early loading of microcodes, since I have found clues in the Xen git logs.
    But I guess Xen does not update the microcode, since the OS in Dom0 believes it is necessary to update the microcode.
    Does anybody have a clue why updating the CPU microcode from within Dom0 fails?

    I have solved the issue by using the Xen early microcode loading with the following changes.
    Copy the correct microcode binary to the boot folder.
    sudo cp /lib/firmware/amd-ucode/microcode_amd_fam15h.bin /boot
    Edit the Xen command line in /etc/xen/grub.conf from
    XEN_HYPERVISOR_CMDLINE="dom0_mem=1024M,max:1024M xsave=1"
    to
    XEN_HYPERVISOR_CMDLINE="dom0_mem=1024M,max:1024M xsave=1 ucode=-1"
    Hardcode the /etc/grub.d/09_xen configuration file to load the binary.
    From
    menuentry "Xen ${XEN_VERSION} / Arch Linux ${_KERNEL_PKG_} kernel" ${CLASS} {
    $(save_default_entry)
    if [ x\$feature_all_video_module = xy ]; then
    insmod all_video
    fi
    set gfxpayload=keep
    insmod ${BOOT_PART_FS}
    if [ x\$feature_platform_search_hint = xy ]; then
    search --no-floppy --fs-uuid --set=root ${BOOT_PART_HINTS_STRING} ${BOOT_PART_FS_UUID}
    else
    search --no-floppy --fs-uuid --set=root ${BOOT_PART_FS_UUID}
    fi
    echo '$(printf "Loading Xen %s ..." ${XEN_VERSION})'
    multiboot ${REAL_DIR}/${XEN_BASENAME} ${REAL_DIR}/${XEN_BASENAME} ${XEN_HYPERVISOR_CMDLINE}
    echo 'Loading Arch Linux ${_KERNEL_PKG_} kernel ...'
    module ${REAL_DIR}/${_KERNEL_FILE_} ${REAL_DIR}/${_KERNEL_FILE_} root=${GRUB_LINUX_ROOT_DEVICE} rw ${GRUB_LINUX_PARAMS}
    echo 'Loading Arch Linux ${_KERNEL_PKG_} kernel initramfs ...'
    module ${REAL_DIR}/${_INITRAMFS_}
    To
    menuentry "Xen ${XEN_VERSION} / Arch Linux ${_KERNEL_PKG_} kernel" ${CLASS} {
    $(save_default_entry)
    if [ x\$feature_all_video_module = xy ]; then
    insmod all_video
    fi
    set gfxpayload=keep
    insmod ${BOOT_PART_FS}
    if [ x\$feature_platform_search_hint = xy ]; then
    search --no-floppy --fs-uuid --set=root ${BOOT_PART_HINTS_STRING} ${BOOT_PART_FS_UUID}
    else
    search --no-floppy --fs-uuid --set=root ${BOOT_PART_FS_UUID}
    fi
    echo '$(printf "Loading Xen %s ..." ${XEN_VERSION})'
    multiboot ${REAL_DIR}/${XEN_BASENAME} ${REAL_DIR}/${XEN_BASENAME} ${XEN_HYPERVISOR_CMDLINE}
    echo 'Loading Arch Linux ${_KERNEL_PKG_} kernel ...'
    module ${REAL_DIR}/${_KERNEL_FILE_} ${REAL_DIR}/${_KERNEL_FILE_} root=${GRUB_LINUX_ROOT_DEVICE} rw ${GRUB_LINUX_PARAMS}
    echo 'Loading Arch Linux ${_KERNEL_PKG_} kernel initramfs ...'
    module ${REAL_DIR}/${_INITRAMFS_}
    echo 'Loading AMD Microcode'
    module ${REAL_DIR}/microcode_amd_fam15h.bin
    Rebuild the grub configuration file
    sudo grub-mkconfig -o /boot/grub/grub.cfg
    And reboot
    Check with the following command that Xen is running
    dmesg | grep xen
    Check with the following command that the microcode has the correct version
    [arthur@orion1695 ~]$ dmesg | grep microcode

    And as you see in this example, there is no attempt to update the microcode anymore, since it is already up-to-date.
    I hope this helps other people facing this issue.

    Reminder that this microcode update will only work by using a floppy disk.
    The file will ask you to insert a floppy disk in a FDD and it will create a bootable floppy disk and put the microcode update files on the disk.
    Then you boot from the FDD and follow the on screen instructions to update the microcode.
