So, I flashed my BIOS/OROM to enable TRIM on my x58 board and while Windows 8/8.1/10 Tech Preview all used to pickup and use any drivers I tried loading, they all now say they can't find any newer drivers (even the ones I guarantee I used to use) but yet Windows 7 install they work fine. I was curious if that flash could make those Windows installers have issues reading the drivers for the controller or something?

Like, literally ~2 months ago I happily installed Windows 8.1 and 10 Tech Preview with 0 problems, I flashed to enable TRIM and now those two versions of Windows won't even let me install since they need drivers and all of a sudden the drivers I used won't work for those OSes.

Fernando, by "Have Disk" do you mean how when you try installing (7 is actually the exact same way) and before you get to your drive/partition list, you have to actually Load Drivers? That's exactly what I'm saying, Windows 7 uses the drivers fine. Windows 8 and 10 TP both recognized the drivers fine as well, and then it literally seemed like ever since I wrote that 1 bit to the OROM (TRIM IS working btw, very nice to the man who found that) Windows 8/10TP both don't want to actually use the drivers as it says "No newer drivers found", yet I can't click Next or anything without loading those drivers...

I'll try flashing back to the old one just to make sure it isn't that, but honestly it's literally the ONLY thing that's been changed since I last used 8/10 TP

OROM is the latest one that ASUS P6T-D V2 can use (10.something) and as far as drivers, take your pick, none of them work on 8/10 TP now.

Like I said, definitely not driver related as I have installed both 8/8.1 and 10 TP on the drivers I've used before. For the record, they are 12.9.0.1001, 13.2.4.1000 and even that 14. one that you posted from StationDrivers. None of them are accepted by 8/8.1/10 anymore for me...... Windows 7? Those same exact drivers all are happily accepted.

Even at that, let's say I tried using old drivers and Windows had newer drivers included. I literally can't get past the "drivers needed" screen that you normally load the drivers at. I click Load, browse to any of the driver directories click OK, it shows 1 driver (I've even went as far as un-ticking show only compatible and then selected each and every driver in that list, no-go) I click Ok, it tries loading it (bar going from left->right) and then says no newer drivers... YET I can't proceed to the drivers/partitions page without loading drivers... lol\

I'm just extremely confused what the hell happened that made these same exact drivers that used to work on 8/8.1/10 not work anymore.

Just to clarify, as you saying Windows 8/8.1/10 TP should all show my Intel RAID array without needing me to provide drivers? Because if so, yea that doesn't happen at all.

Hmm, I'll have to dig into it more than, but yea it's just strange how Win7 can "load" the driver fine, but those have been giving me problems. I suppose I could just give up on "native" TRIM support, and re-flash back to "stock" BIOS/OROM since all I did was change that one digit I think it was, basically followed the instruction.

Correct, following the hex edit method in the post on here. I can't seem to find the post right now. Like I said, in Windows 7, everything works fine, trim and all, it's just the installer for 8/8.1/10 say there's no newer driver if I try loading any of the drivers I mentioned, even that new 14.x.x.x version.

Just to keep this updated (I'll edit this post with the next results) and after flashing the BIOS back to stock Windows 10 TP as well as Windows 8.1 installer both picked up the drives, and also allowed me to load the v12 RST drivers. Going to literally "Replace" the Intel OROM is the exact same BIOS file with Intel-RST_RAID-ROM_v10.1.0.1008_TRIM-in-RAID0-mod-acc-CPL0 and report back. I'm 99.9% certain that's exactly what I did originally and it didn't pickup the controller/allow the drivers in 8.1/10 TP.

EDIT: Super interesting. I took the exact same BIOS file that had working TRIM originally, and (for what I can only call) "re"-replaced the existing (again... TRIM working according to trimcheck-0.7) Intel OROM with Intel-RST_RAID-ROM_v10.1.0.1008_TRIM-in-RAID0-mod-acc-CPL0 and Windows 8.1 and 10 TP both picked up the drives as well as v12 RST drivers.

Either way, from the looks of it on a P6T Deluxe V2 1202 BIOS with Intel-RST_RAID-ROM_v10.1.0.1008_TRIM-in-RAID0-mod-acc-CPL0 is now working with TRIM and 8.1/10TP. Next up, inserting SLIC. :P
