This post is now irrelevant. See this post instead.
Due to the recent requirements of Secure Boot and/or TPM, I have revisited this board. I currently have a X99D3M4 v1.11 in hand for a few more months. To summarize the last few weeks:
- I bought the iEngineer MACHINIST E5-K9 V2.1 CX99DE76 BIOS, but it simply did not boot. Same story with the older CX99DE55 version
- After a lot of BIOS testing (mostly Machinist, Jginyue and Angxun), I have finally gotten the Jginyue X99-TI D4 PLUS BIOS up and running. The only benefit over the other BIOS I have provided in this thread, is that Secure Boot works. Nothing else.

Changelog for “FIB_J99TI402_250831.bin”
- Fixed non-working Ethernet and 100 MHz FSB, by transplanting just the Jginyue BIOS region (8M) into my existing X99D4M4 complete BIOS file (16M)
- Fixed the PCIe X4 slot, by setting “IIO 0” to “Auto ; x4x4x4x4 ; Auto”.
- Secure Boot and Resizeable Bar is enabled by default, by using AMIBCP
- Unlocked RAM timings
- Untested for now since I only have a DDR3 board in hand: Default values should enable CPU overclocking with for instance Throttlestop
- Most importantly: Changed the startup logo
Known bugs
First startup on Failsafe settings is extremely slow. Once you have loaded “Setup Defaults”, then the startup time is still slower than before
Next steps
- Solder on pins on the Debug port (I have already verified with a multimeter that they are indeed connected and show typical JLPC values)
- Map the pins, like I showed in this thread
