Ok, I'll get to it in the morning. Thank you very much for your help and good night. 😊

OK, thanks! Sorry I was not fast enough, I tried Have a good night!

Good morning Lost_N_BIOS. There's good news and bad news. The good news is the modded BIOS has the serial port option unlocked, which is excellent. The bad news is I looked on the Windows 2000 Insydeh20 forum on msfn and they said you also need the parallel port as well. So, very sorry for the inconvenience, but you think you could also unlock the parallel port option as well? Again, very sorry for the inconvenience as you've been a great help.

@SamsungASUS - Thanks for quick report back! Yes, I made sure the serial port would be visible to you first by itself, since that was what you mainly mentioned wanting. Don't worry, it's OK, I can do the parallel port too, just skipped it since you didn't mention needing it.
Someone else was wanting this fully unlocked to. Do you mind taking images of ALL BIOS pages, ALL settings, so I can see what all you see and know what else needs revealed? Then I can really unlock it all.
Please resize images if you can, to 1000px wide, then put in max compressed zip. I don't need 4K images just to look at BIOS settings

Ok, sorry if this isn't 1000px wide, as I took the photos with an iPhone, but hopefully their wide enough. Also, sorry but the website won't let me upload the zip file because even when max compressed with winrar, it is too big, so hopefully these photos will do, again very sorry.

@SamsungASUS - I cannot use the above images, must be in a zip for starters. And 1000px wide is what I'd like sized DOWN to, not "hopefully they are at least 1000px wide" Most phones and modern cameras take images that are 3-5K (WAY TOO HUGE for our needs here)
I am on limited internet, and only need to look at small picture, for a second, so don't want to download 100MB of images I will only look at for a second, when the zip could be 2-5MB instead, if user resizes images.
If you cannot resize the images to smaller, OK, but please put all in a zip. Actualy, here, there is online batch resize websites, such as these below, that you could use, then put in max compressed zip, then upload here or to any free file host.

https://imageresizer.com/bulk-resize

I checked, those are 3MB per image and 2.5K wide, much too large for me to download just for this kind of thing. Please resize and then zip, thanks

Ok, sorry the pictures were too big, these pictures may not have the best quality, but hopefully their much smaller in size. And they fit in a zip file way smaller than 2-5 MB. And sorry for the wait, I had to go somewhere.

@SamsungASUS - Thanks! Never a rush here, I am always behind and buried anyway, so I can only go fast sometimes
Image quality doesn't matter, as long as I can read the BIOS page/settings, that's all I need, I'll only look at them for a second as I do edits and flip between pictures.
* Edit - Ohh yeah, that is BAD/Low quality, but, at least it looks like I can read them for the most part

That's good. I didn't really know how to use the photo compression tool on iPhone. But do you have what you need to make the new modded BIOS?

@SamsungASUS - It probably would have been better to use either one of the sites I linked, or picked a better quality than extreme lowest option (It still was not 1000px >>> 1958px)
Anyway, yes, that was all I needed! Here is full manual unlock of all settings, some may not function, or may not be compatible with yoru hardware, so do not change anything unless you are sure of what it is.
I also included a IFR text readout of all possible settings too so you can search/scroll to look through what is there (a select few I left hidden, for safety reasons >> Mainly Power-on password, user password etc - Too many people with BIOS password issues, this shouldn't be a thing )
I did not find any parallel options in there, unless it has some other name? - https://ufile.io/nx0y5e5j

Please let me know if all OK, thanks

*** WARNING - To ANYONE with laptop and unlocked BIOS!!!! ***
DO NOT try to enable this graphics card or disable that card, switch cards etc. Otherwise you will end up with no display output (ie black screen) and no way to recover except by blind flash or with flash programmer.
You can change graphics related settings, like changing memory sizes, or core speeds etc, just don't try to disable one card or change which is main etc.
Additionally, be very careful when trying to undervolt CPU, you can leave BIOS unbootable due to CPU voltage too low (Sometimes even 0.05 is too much)

@vickyk1293 - Do you mean, on the original BIOS the NX bit setting and the AHCI setting are hidden? If yes, I did not know, so I will need to redo this edit, but anyway, here in this thread I did unlock for someone last night.
Your post is kind of confusing, you say you have Adv/Power, but then say they need to be made visible?

Anyway I do all my own edits, so I wont be using any file you attached here, I edit the stock BIOS from scratch so all edits are mine and any that need undone or changed I know where they are and why etc.

Sounds like a bad BIOS at the second link anyway, 3-4 people confirm same issue and it's bad cause/effect (read the blog)

Here, I did full unlock manually on 3110 for another user today, once you reply here I will merge your post with his thread
Acer Aspire One AOA150 BIOS Mod (2)

Ok, thank you so much for your help. I'll try the modded BIOS tonight.

You're welcome! Yes, please let me know if it's all OK. Sorry there is no parallel option here, not sure what you can do about that, maybe remove whatever from the OS ISO that needs this?

Alright, I can't get Windows 2000 installed with ACPI Multiprocessor PC, but it's not your fault. Maybe the Insydeh20 BIOS is too complicated to install that OS on. If my other methods I'm trying now doesn't work tonight, I'll contact the original author of the post where he said the directions of how to install Windows 2000 Professional on an Insydeh20 BIOS. In the meantime, you think you could help me with another BIOS mod? It's the BIOS to the ASUS Prime B450M-A/CSM motherboard I have.

@SamsungASUS - It's probably that the BIOS or hardware is too limited. If there is a parallel port on this board, which I doubt, there is no control for it in the BIOS. And if that is what is stopping you, can't you remove this function/feature from the ISO installer before you try to install, that way it's not stalled there?
Not all Insyde BIOS are the same, and certainly not all systems are same hardware-wise too, so what you found really only applies to the exact model that person was using

So, the full BIOS mod is OK, correct? No strange issues, all settings there now etc? If yes, thanks! I linked another user here today, that I will merge to this thread too as soon as they reply back
They were wanting full unlock, and found some of the older BIOS unlocks you mentioned, and the blog about the bad BIOS too that overheated too quick for users to reflash other BIOS without freezing their systems

Yes, I replied to you on that other thread I think. I will find it now
