@Kebicle - See my edit above, I posted the follow up BIOS for you in advance in case you need I know about CSM/Legacy ect, but not sure what you're wanting me to google.
However, yes, I am aware Win7 and older is major pain on some systems, due to them OEM's and Intel/AMD trying to get rid of legacy altogether, and in some BIOS this is impossible due to stuff stripped out (other times, it's just hidden)
For that we have entire section on this forum where you can get help from others more familiar with that about how to edit BIOS or OS install files etc so you can install Win7 on non-compatible systems.
ON this subject, I am not familiar with helping, I only know BIOS editing

First result in google from Win7 UEFI no CSM, looks solved to me - https://forums.mydigitallife.net/threads...hout-csm.79551/

@Lost_N_BIOS So i selected legacy using the first bios and after a few reboots (idk what it was doing) But then it reselected back to uefi. Ill try the second bios file now.

If second BIOS fails too, I can hard set legacy but then it may just boot loop or keep resetting (less doubtful that would be possible after hard set) if that's what it's going to do
.

@Lost_N_BIOS The second bios permenatly froze when going selecting the boot tab and doesnt load anything and is on uefi by default (in case you need that info). Have any ideas on how to fix that? the first one didnt freeze but deselected uefi after rebooting several times on its own

@Kebicle - Yes, here, try this one instead to see if same, then if same I will just edit first BIOS I sent you and hard set Legacy so you can test (Making this now, will add shortly)

Thank you. I’m unable to test this for the next 4 hours but once you are done setting the hard legacy setting can you upload that to the same post? That way I can test both. Thanks for helping me with his by the way.

@Kebicle - Sorry for delay - Yes, here you go, if above one fails then this is built on one that lets you set legacy, it will be set by default now anyway too. So may just boot loop endlessly

You're welcome! Sorry if we can't get it sorted out, if not then it's Intel's fault for forcing companies to do away with legacy

@Lost_N_BIOS The 1st one was still frozen on the boot screen and the second one reverted to uefi somehow. It seems like the bios enviorment cant run in legacy. Any last ideas?

@Kebicle - What do you mean first one was frozen? I only posted one BIOS there, and the BIOS in post #52 should not be possible to revert, but if so I guess nothi9ng we can do.
When you say first one, do you mean BIOS in post #36? If yes, I thought you said that one was OK, but on reboot reverted back, so I built all rest on top of that, specifically this last one.

No, only thing I can think of is what I linked you to above at #46, and I expanded on that at your new thread too, and tagged in legacy pro user I know here

@Lost_N_BIOS Post #50 The first bios still froze at the boot menu, and bios is post #52 still reverted. It shouldnt of been possible to revert but it must of somehow. Thanks for tagging the user.

OK, I see now. Yes, 52 should not have been possible to revert, but to me this says not possible to use in this manner. So you will have to find way to install Win7 UEFI mode, or give up on Win7 and go Win10.
I held back forever, even tried 8 and 10 for a while each time they came around, and went back to 7 all times I tried 8-10 and I did give them fair try too, but now have been using 10 for a while and it's OK now that I've used for a while. I prefer Vista personally, but you know...

@Lost_N_BIOS Haha, Im going to give it a solid effort to install windows 7 over uefi in the other thread. Never used vista before.

Good luck, hope you can get it! Vista is the best Win7

Google Drive

A while back I requested someone to mod my BIOS in order to unlock all available settings. They did so, I flashed it, and it worked. I had to get my laptop repaired at some point, in which case the motherboard was replaced, and the BIOS mod was lost.

I tried re-flashing the old modified BIOS back to the new motherboard; it worked, but POST took a good 1-2 minutes now (I'm assuming there was a checksum issue or some kind of timeout). I didn't want to deal with this.

Did a little bit of digging yesterday, and found a copy of H2OEZE. I loaded up the old modded BIOS, and compared it against the new unmodded BIOS. Found that only the SetupUtility module was different, so I extracted it from the old modded BIOS, and replaced it on the new unmodded BIOS. I also ran it through me_cleaner (PR #282 required) to set the HAP bit. Flashed it, and all was well (POST was instant, and all settings were unlocked).

So I'm thinking this could be applied to any BIOS dump with similar firmware, or at the very least, any PH315-51 laptop.

On the Google Drive link, I provided 4 files:

1-old-modded.bin - The modded BIOS from the old motherboard
2-new-unmodded.bin - The unmodded/stock BIOS from the new motherboard
3-new-modded.fd - The self-modded BIOS for the new motherboard (with the SetupUtility module from the old BIOS)
unlocked-setuputility-module.ffs - The SetupUtility module (modded for unlocked settings from the old BIOS) extracted with H2OEZE

Perhaps the 3 BIOS files could be compared to see what was exactly changed for anyone interested.
