@Lost_N_BIOS Thanks once again for your work on this project.

However, I am a bit confused: Regarding the FL1 and FL2 files, is it the FL1 file which contains the RAID OROM? If so, it is just the FL1 file (or BIOS.WPH when decompressed) that needs to be modified, correct? If so, is the modified BIOS.WPH which you have kindly provided is a decompressed version of the FL1 file? If that's the case, could I use one of the tools mentioned in the previous posts in this thread to recompress the BIOS.WPH file back into the FL1 file and use the Lenovo BIOS update tool to flash it?

If not, do I use this WinPhlash tool and select the BIOS.WPH tool to flash to the laptop?

EDIT: I used phcomp.exe from here to compress the BIOS.WPH file that you provided and it compressed it to a 2,072,686 byte WP2 file - the original $01C0000.FL1 file from the Lenovo BIOS upgrade package is 2,072,768 bytes (slightly larger) - would this be a problem?

@knubbze - You're welcome! I too was confused, that's why I paused!

No, the only modified file is BIOS.WPH I included separately outside of the "app" folder. This is the decompressed FL1 file, FL2 does not contain the part of the BIOS where this rom is located so it was not modified.
I assumed you could use BIOS.WPH with WinPhlash, or compress it back into a new "FL1" file, up to you to see which works or what you want to do etc.
I also included the e_bcpvpw.exe I used to decompress it, so yes you can use that to compress back if you want and replace the original FL1, or flash BIOS.WPH as it is with the WinPhlash.
I assumed there may be some check in the Lenovo tool, so I didn't compress back to FL1, and also mentioned you may need to use a non-Lenovo WinPhlash (not included)

I do not think size of the newly compressed BIOS.WPH would be an issue, but don't use it to replace FL2 (replace and rename it to FL1, or flash by itself as WP2 or WPH - or flash it non-compressed by itself as is how I sent BIOS.WPH)

I don't know what works and what doesn't in flashing BIOS on this system, or with these kind of split up Phoenix BIOS New Style.
Personally I wouldn't do anything without a flash programmer in my hand, but that's my years of experience talking (price is less than $7 for CH341A + SOIC8 test clip w/ cable)
Once you have that, you could dump BIOS and edit directly, and there would be a single BIOS image and none of this confusion

@knubbze - Good to hear things are going better for you now!! Where are you located in the world? Then I can give you ebay or amazon links (if you can order from amazon, probably faster than ebay/china, but will be more $$)
If you order from ebay/china, it's cheaper, but you can get from ebay or amazon faster for more $$, all depends on where you are I guess.
You need CH341A + SOIC8 / SOP8 test clip with cable, and depending on BIOS chip you may also need 1.8V adapter. This is only $3 more, best to pickup even if you don't need, in case you don't want to open laptop until it's time, or it may come in handy in the future anyway
Since this is very old system, you probably will for sure not need the 1.8v adapter, but it's best to grab all at once, so you're ready to fix anything in the future. All this comes in bundle kits, or by themselves one item at a time.

Second system may just have a dead BIOS too!?
If we do anything with your working system, you should dump it's own BIOS, then we check to be sure it's valid/OK dump, then edit that and you flash it back.
Nothing should come from the second system, in case it's BIOS is corrupted

@knubbze - Yes, that is correct item, and all you need, unless your chip is 1.8v type
Which exact post # on that page that you linked, is the whitelist BIOS? I see last post says NO idea if, where or how it works. NO guarantee either." And then no users replied after that with any testing report info?
Ohh, that is the file you are talking about, I see now from the sendspace link

The FL1/FL2 files are used with official update methods/program, those are bin/rom too just compressed, and FL1 is the BIOS file.
Looks like he may have edited the flash package, or just the included flash method info allows mod BIOS flashing, so we may be able to use this to flash in mod TRIM BIOS
Or, maybe, from the get-go, I should have edited the decompressed rom/bin for you instead of sending back WPH?

Anyway, I will now edit BIOS.bin/rom from official BIOS for you, unless you also want the whitelist untested BIOS edited too?
Let me know, then I will make edit, and put the mod BIOS into that flash package you linked, and looks like you may be able to flash it in then

You're welcome! Always happy to help, when I can

@Lost_N_BIOS - thanks for your quick response! Would it be possible to mod both the official and whitelist BIOS?

@knubbze - Yes, I thought you might say that, I knew I should've went ahead and made them
Watch this space for edit shortly
-------------------------

* Edit @knubbze - Here you go, hopefully it will let you flash
Follow the outlined directions that were included with that original Whitelist BIOS, I left a copy of this inside each package

Awesome! I will try to flash it this weekend and report back.

In the meantime, out of curiosity, I took the laptop apart and managed to dump the BIOS with the CH341A interface that you recommended!

It's an 8MB file, and I've uploaded it here: https://files.catbox.moe/j5xb3j.bin

Would you be able to take a look at this file (just in case flashing the files that you provided doesn't work), and patch it if you are able to?

All of my thanks once again for your incredible work!

@knubbze - Before I do anything w/ that file, what is the BIOS chip ID (look with your eyes, don't rely on what any software told you). And what software/version did you dump the chip with?
I ask because some chips only compatible with certain software/version, so any dump made other than that may be invalid and would certainly fail on write back with same software/version too.
I may have you dump it again before I edit and send back.

You're welcome, and thank you too!

@Lost_N_BIOS - Unfortunately, there was a sticker on the chip which obscured the text printed on the chip. I peeled it off, but the text is faded, and very small, making it impossible to read with the naked eye. I tried to take some photos of it and zoom in, but it's still too fuzzy to read. However, I found a PDF of the PCB schematic for the motherboard, which lists it as a MX25L6405DMI-12G, which matched what the software's 'auto detect' feature identified it as.

Here's the section that specifies the BIOS chip(s): http://0x0.st/ih9U.png

I've uploaded the motherboard schematic PDF here if it's of any help: https://files.catbox.moe/uc0vyf.pdf

The software I used was 'CH341A Programmer v1.18' which was provided by the seller of the interface that I purchased. They also provided a v1.34 version, which provided a bios dump file with the same md5sum checksum as the one dumped by v1.18.

I haven't re-assembled the laptop yet, so I can re-dump with different software/settings if required.

Use magnifying glass and flashlight. If you have to, clean the chip with alcohol and or damp warm rag, then rub white thermal past on it and wipe off, then look again.
Or yes, we could rely on what you mentioned, sounds like it should be correct since both of those things match up. Sometimes they switch chips mid-production, or several lines produce boards with different chips etc, but I think PDF and autodetect picking same thing is good sign that's what it is.

Unfortunately, I only know for sure about MX25L6473E and for that you have to use >> Use CH341A v1.31(1.4) (CH341AFree) - choose type 25 and correct BIOS size (64 megabit = 8 megabyte (MB) in this case)
Which is included in this package - http://s000.tinyupload.com/index.php?fil...213094641136166

1.18 and 1.34 read both matching is good, probably means both for sure read this chip OK, write is the main issue though, if either fail to write properly then you're stuck.
Hopefully 1.18 will be OK, it's kinda old default that works for a lot of chips, and this is old chip, so hopefully it will be OK
For now, we don't have to worry anyway, until you try to flash those two BIOS and both fail to allow a flash, then we'd be forced to go this route.

Well, good news! I flashed your modified TRIM BIOS using the included WinPhlash64.exe, and the flash appeared to be successful, and the system rebooted fine. So then I flashed the whitelist version (as the instructions included with that say to flash the stock BIOS first), and again the flash process was successful, and the system rebooted back into Windows. So I am very, very happy today! You're the best, @Lost_N_BIOS!

Now that the hard work is done, how can I test that the TRIM function is working correctly?

@knubbze - Great to hear all went smoothly and hassle free with the flashing! You're welcome, and thank you again too!
Here's how to check, and or enable/disable >>
https://www.addictivetips.com/windows-ti...ssd-windows-10/
https://winaero.com/enable-trim-ssds-windows-10/

And here it how to confirm it's not only enabled, but working. Run this once, wait 30 seconds or so, close it, then run it again and it will confirm if TRIM functioning properly or not.

@Lost_N_BIOS - brilliant, thanks again for the valuable information!

One last thing (I promise!) - the OROM version in this BIOS is v9.5.0.1037, correct? Would you or @Fernando happen to know which driver version would be the most suitable for this OROM version? I couldn't find any mention of v9.5.0.1037 drivers in @Fernando's threads.

@Fernando - in case you need my system information to make a recommendation, the chipset is Intel QM57, and I'll be running two SSDs in RAID 0 mode (OS is Windows 10).

Thanks guys!
