How to use intel flash programming tool download#You need to download the tools listed under Intel ME System Tools v9.x How to use intel flash programming tool serial numbers#In this post we are only going to discuss and use it to update the CPU microcode, for other usage I suggest you read the relevant topics on , here and here.įirst we need to dump our current bios with all DMI data like product name, serial numbers (otherwise the DMI data won't be preserved) using the Intel's Flash Programming Tool, which can be obtained through and listed under section: "C2. to detect the versions of the OROM/EFI modules, which are inside an AMI UEFI BIOS file andĪ) the most important OROM/EFI modules, andī) the CPU microcode of any AMI Aptio UEFI BIOS.The UBU tool is very easy to use and able How to use intel flash programming tool series#This guide is aimed at my own system, which is a HP Pavilion Desktop - 500-405nd with a Intel Core i7-4790S (Haswell) processor, but might work for for other models in the HP Pavilion 500-0xx/ENVY 700-0xx series with different processor configurations, use it at your own risk! It does not update SPI descriptor or other regions.As it takes ages for HP to complete the microcode updates that protect against the Meltdown (CVE-2017-5754) and Spectre (CVE-2017-5715) vulnerabilities for HP Pavilion 500-0xx/ENVY 700-0xx series (ROM Family SSID 2AF7) desktops I decided I would give it a go and update it manually using UBU. SBL capsule can update ME and BIOS region only. And FPT is only supposed to be used during manufacture time. But in general, I agree we should use the SBL capsule for FWU. In this case, UEFI payload can still handle SMI. It just allows SPI write when CPU is not in SMM mode. Can you please help figure out what’s going on? I double checked and I’m pretty sure I didn’t touch Ps2sBar, and also I trigger firmware update from SBL shell. I’ve already performed firmware update and it nearly done, but it stuck right here:ĪSSERT d:\xelex_s_bios_sbl\src\bios\sblplatform\SblOpen\Silicon\TigerlakePkg\Library\FirmwareUpdateLib\FirmwareUpdateLib.c(107): P2sbBar != 0xFFFFFFF0 Also do you run FPT under UEFI shell or under OS ?įrom: On Behalf Of Kiet Pham Sent: Saturday, Octo12:47 PM To: Subject: Re: Using Flash Programming Tool cause Flash Access Error Which payload are you using ? If it is UEFI, where did you get it from ? This is important because some UEFI will enable SMI to protect SPI flash. Can you dump DWORD at I/O port 0x1830 ? What is the value ? 3. Can you dump your PCI CFG space register bus 0, dev 0x1f, function 5, offset 0xDC ? What is the value ? 2. To further understand what protection was enabled, could you please check the following ? 1. Just a reminder, for final production, the SPI has to be protected to prevent attack. Also, I run FPT tool in UEFI Shellįrom: Using Flash Programming Tool cause Flash Access ErrorįCERR indicates there are other SPI protection was activated. Ð Our payload is UEFI payload based on Reference Slim bootloader for Tiger Lake UP3 (MR3). Also do you run FPT under UEFI shell or under OS ?
