For example on an Optiplex 760 which had BIOS revision A03 significantly out of date compared to the latest A16 release. If you have a BIOS revision lower than the latest version.

Note the release date on this page may be slightly different to the date of the BIOS revision on system information because it takes Dell some time to test the update before they make it public. In the case of my XPS 8300 it already has version A06 and hence is up to date.

You will see the latest revision at the top and all subsequent versions Dell released. Type in the digits of your model number in the search box and press the right arrow until you find your model: Press and on your browser this will open up the search on the page.

If your system is not a Dell get the driver from your appropriate OEM for instance HP or Lenovo.

Dell Drivers and Downloads only lists the latest revision whereas the Dell FTP website lists all the revisions for the model. the attempted update from A03 to A12 may state that A06 should be installed before A12. I do not recommend downloading the BIOS update from Dell Drivers and Downloads because sometimes BIOS updates require older BIOS as a prerequisite. If its available (Windows 8 and later) also take a note of the: This guide has a complementary tutorial video. Upgrading to a Solid State Drive and Altering the SATA Operation in the (UEFI) BIOS Setup.

Determining if your system has a UEFI BIOS and SecureBoot and Notes Regarding the Windows 10 Upgrade.Determine your BIOS Revision using System Information.Orange - upper bytes of BIOS region limitĭark-blue - upper bytes of GbE region limit If you don't familiar with structure of Intel descriptor region, here is an annotated HxD-screenshot of affected part: During the debugging of strange behavior of using UEFITool with Gigabyte BIOSes, I have found either a bug or a special non-standard region map configuration in all recent Gigabyte BIOS images.Refer to my new guide: Unified Extensive Firmware Interface (UEFI) Contents It got into BIOS recovery mode and I had to recover the original BIOS. So, this region map says to us (and to chipset logic too, if flashed to SPI chip as is) that:ġ. I do not know whether this is expected or maybe there is some trick to it. Or maybe the image was rebuilt OK, but it verifies signing (can it be signed) and refuses to boot. Uefitool image or bios region minipro programmer download#Īs a side note, UEFITool0.21.5win.zip cannot download correctly as it is blocked by antivirus. GbE region starts at offset 0x1000 and ends at 0x3000 (0x02 + 1) * 0x1000, which is correct.Ģ. ME region starts at offset 0x3000 and ends at 0x200000 (0x1FF + 1)* 0x1000, which is correct.ģ. UEFITool is a cross-platform C++/Qt program for parsing, extracting and modifying UEFI firmware images. BIOS region starts at offset 0x0000 and ends at 0x800000 (0x7FF + 1)* 0x1000, which is obviously incorrect!īIOS regions should start at any offset between 0x200000 (end of ME region) and 0x250000 (begin of first firmware volume in image file) and end at the end of image file at offset 0x800000. ICSP interface (6-pin interface of the programmer right side) is limited to the TL866A model.

It supports parsing of full BIOS images starting with the flash descriptor or any binary files containing UEFI volumes. Uefitool image or bios region minipro programmer full# Partly Microchip’s MCU with More than 40pins require the use of the TL866A for ICSP interface programming. Most of Microchip’s PICs MCU support programming on ICSP and 40PIN seat. Original development was started at MDL forums as a cross-platform analog to PhoenixTools structure. So, the right values for BIOS base and BIOS limit should be 0x0200 and 0x07FF respectively. The current setup is dangerous by security means (Descriptor, GbE and ME regions are accessible, because they are parts of BIOS region now), it breaks Intel specifications, breaks normal use of FITC utility and simply damn wrong! This setup will have no unallocated space in SPI chip and no intersections between flash regions. That's why some GB files are having debug-message about intersections in version 0.7.0. UEFITool will permit you to extract data from an image, insert items within the structure of the image you will also be able to insert or remove unwanted pieces as needed. I have sent report to Stasio using TweakTown Forum PM, and hope it will be corrected soon.Ĭlick to expand.I saw this too when i tried with z68xp bios. Upon completion of the editing process, you can easily export the image. The point is the total Bytes Free at the end of the report.
