- sorry for the long delayed reply, I've been busy and haven't got into the site lately. Great the mod BIOS is working for you better now, and you're not missing those kill shots
Anytime you can flash stock BIOS using EZ Flash, unless it stops you from doing that due to security issues or version rollback issues. There is ways around that too, google asus BIOS rollback.
If you want to enable the settings I changed for you on some older BIOS, then you have to modify with AMIBCP and then put back on using your programmer, or Intel FPT.
For either of those, I suggest you flash to that stock version, then dump the BIOS via FPT or programmer, then modify that, then put it back same way you dumped it.
There is no security that can be stopped when using CH341A, you can program anything you want with that. If you don't dump and modify backups though, you will loose your serial #, UUID, DTS Key, LAN MAC ID etc. So always dump BIOS, mod it, then program back, don't program stock from Asus
Once dumped, you can edit in any CPU microcodes you want, or ME version using this ME Cleanup guided method - https://www.win-raid.com/t1658f39-Gu...alization.html
Here's my guide on ficing _FIT_ table if you edit the microcodes, little bit on microcode editing in that but it's copy/paste so not much for me to say on that in the guide
I doubt settings are missing from new BIOS that were in old BIOS, maybe a rare setting here or there but not usually, probably just in another location. New BIOS add a lot more than CPU compatibility, they fix issues/bugs, add improvements and enhancements all kinds of stuff like that, not just making CPU's work.
