hi all i have got a dump from my dell 7810 from a spi flasher im trying to work out what is best to do with the bios can i remove region setting and is there any extra menus i can enable im going to be removing the microcode 06F2 for my xeons turbo
i cant share the file but if someone wants to have a look i will put on dropbox
So to update I managed to remove the microcode 062f and reflagged the bios chip no issues computer boots up I see v3 turbo all cores pop up.
Now can’t boot into windows can select boot options and now trying the win 10 cd to recover
If anyone wants how I did it I’ll take pictures
But in essence
Bought a 8 pin ic clip and jumper leads
Used raspberry pi spi gpio pins
And a lot of praying to the silicon gods
After restored bios, look for ME service jumper, put in service mode and use the Intel FPT tool from the correct ME package tools and make a full spi dump and a bios region, restore the ME jumper, work the mods on the bios region, flash again with FPT tool the mod, if it fails you need to set the jumper back to service mode, this jumper must be set to default setting for a normal working state of the system after flashing ONLY the mod bios region.
Dell system/and or specific Dell motherboards has it own way of recover the system bios, its your task to search for it on Dell documentation, the SPI programmer is the last resource when everything else fails or to froce a mod flash.
Yes, thats the FPT tool operation, reading ONLY… a simple write method to test:
Dumping: ftp -bios -d biosreg.bin then testing the write access: fpt -bios -f biosreg.bin
If successful, you know that you can write the in the spi.
Carefull, this tool doesnt care what we told it to flash…it doesnt care if its a correct/mod/corrupted image.
Learn the tool cmds/options.
Note that this tool is not the proper tool to update ME FWs, just to clarify that all i referred was due to a mod request and flash, not ME related.
EDIT: What i verified is an updated mcode and you had removed an old mcode revison 38 and also removed the 06F2…now my friend, from this on, im not here to assure you nothing more concerning the success or failure of the system, these are user choice only and their own risks… after all, this mod world.
So I flashed the bios chip via my raspberry pi all went ok.
It took a few attempts to boot but made into windows did a dump via ftpw in windows checked with mmtools micro code 06f2 has been removed.
Patched the efi with the turbo unlocked mod
Booted into windows all 32 cores turbo.
hi all after lots of reading and help from people on here i managed to dump bios with pi and soci clip i have no problem getting my fd unlocked or any other locks off now i have modded the mb to make the service pins usable.
my issue is every time i flash bios back even with minimal changes - remove microcode for the Haswell, enable overclocking feature/overclock lock, i tried to enable a few bios features but that never works even after changing to user,
i cant get past dell recovery logo just hanges and crashes but i can get into bios and f12 boot menu
the procedure i use is
power off pc
2.unplug pc attach soci clip
3.conect soci to pi
4.power pi up
5.flash chip now errors
6.turn pi off before removing soci clip
8.plug pc back in
am i missing something in my procedures.
i reverted to the latest dell bios A34 and want to try again.
i few places i have read the smbios version 2.8 has been leaving user with the same boot loop problem can anyone shed some light on this if possible.
How are you “touching” those features? AMIBCP tool?
Are you modding an original dell bios update file, a full spi backup or a bios region?
AMIBCP wont work on all modern Aptio V bioses as it was in Aptio IV, thats why you can see a lot of users that must use RU/IFR extract tool and hex edit the variables/strings.
This is due NVRAM DEFAULTS and other modelas besides the SETUP, this must be done with RU/IFR extract tool and edited. The strange part is only modding the mcodes, your issue still persists…
Its better to work on a bios region and use the FPT tool to flash only the bios region, not touching other regions.
EDIT: I said Bios_region only, not the full spi dump. This dump has ACM/RSA…this is not welcome in modding.
Try just the mcodes with AMI MMtool or UEFItool besides UBU, on the region.
According to the ME of your system:
Dumping: FPT -bios -d biosreg.bin
Flashing: FPT -bios -f biosreg_mod.bin
This is not an easy bios to mod…too much Dell in it, in structure/modules/NVRams…
EDIT: Ok then you understood it… but here it gives 8 388 kb not 8 192…
HEX edit was not ment to mcodes, that was used in older 1/2/4Mb bioses.
I opened the file with MMTool and UEFI…too much of Dell DXE/PEI in it, not a bios to touch myself, sry.
