Ask @Scruffy what volume contains dxe modules on Dell

22

or better put the readable bios by uefi tools here

23

You can download my UEFITools readable bios here

24

50mb bios :smiley: never seen that.
try this and report backrebar_nvmeboot

added rebar and non dell nvme boot from pcie

edit: bios from dell file is 18mb in cap format, so in .bin should be 16mb for 128mbit rom.
ur bios is 50mb… i think it is dump of all bios in the server like bios+idrac+ec+otherbios rom.

@Scruffy Thanks for your help.

Dell’s .cap format does not contain the raw firmware bins, they’re LZMA compressed in there. That’s how an 18MB .cap became the 50MB I shared here. That said, when I look carefully at what UEFITools shows me, it looks like everything there is duplicated twice. I guess it could be that the bin contains two redundant copies of the bios for two redundant EEPROM chips on the hardware? (and maybe also some firmware for other bits)

I won’t be able to try this out until I can find Intel’s Server Platform Services system tools package (compatible with v04.01.04.901 in my system) providing a working FPT tool for my system though.

Can you tell me where you placed the new FFS modules in the mod you posted here? And can you link me to a description of the nvme boot from pcie mod you included? I’d like to understand that a bit better.

here is the position where i placed rebar and where i did remove then insert after for nvme dxe.

27

tried CSSPS4 yet?

28

Yeah, I’ve looked at those CSSPS4 downloads. Those archives contain firmware .bins only. I need the system tools package, with a FPT .exe that I can use to flash/dump my running firmware. Basically the equivalent of what’s linked in the downloads section of part C of this post, but for Server Platform Services (SPS) instead of CSME (the consumer grade stuff). It’s frustrating because downloads for the thing I need have been posted several times on this forum, but the links for them have all suffered link rot. I know someone here must still have it!

29

ok. I found the correct flash tool. but the bios EEPROM is write protected :frowning:

spsFPTW64.exe -BIOS -F backupA-6.bin

and I don’t see a service mode jumper on the hardware

try with uefi fpt if available.

try also 2 thing:
1)save bios with spsfptw64.exe -d bios.bin
2) try save bios region only with spsfptw64.exe -bios -d biosregion.bin

upload bios region bios somewhere.(with -bios command option 2)
