[solved] Asus Eee PC 1201N ahci unlock
#51
YEAAAA I'm made it !!!!!
Take the memories out, and there are some pin contactcs on the board where it says BAT with an screwdriver head simply move throught the board to make a short contact on this pins. This will reset bios.

My 1201n is alive again!!!

Guys, I have problem Smile I use my SSD with AHCI enabled, but sometimes the modified bios just wont detect the SSD. It looks for it for a long time, and then sometimes it just does not show up.

If I press f2, enter the bios and press f10, followed by ENTER - it is all good.
Any idea how to fix this?

HELP needed

I have my 1201N modified with this BIOS and a 250Gb SSD. All works well in IDE. If I change the settings in the BIOS to AHCI it attempts to start windows but fails every time. It gets as far as trying to make the windows symbol and then a short message (text) flashes across the screen (to fast to read) and it restarts with the same effect.

Reverting to IDE makes the machine work just fine.

How do I freeze the machine to be able to read the error message? Any ideas whats happening.

All suggestions will be appriciated as I seem to be stuck now

OK found how to deactivate automatic restart, had a BSOD 0x0000007B error.

Found this solution on the Samsung website (Using a 840 EVO), cloned existing IDE drive! so did not change to AHCI before installing (copying) windows.

When Windows is installed without enabling the AHCI mode in BIOS setup, an error may occur during the booting.
Change the settings as shown below, or reinstall Windows.

■Go to Start>Run, and then enter ""regedit"" in the Run window and press Enter to launch the Registry Editor.
■HKEY_LOCAL_MACHINE > SYSTEM > CurrentControlSet > services > msahci In this menu, you will see an item named Start. Double-click it to change it to ""0""and then reboot.
■Enter BIOS setup, and change SATA settings from IDE to AHCI.

AHCI now works, hope this might help others as well!!

There's a little surprise in the Security section, I hope you'll find it interesting Wink
Photos of AHCI confirmation would be appreciated.

hello,i m a new and really thankfull user in this forum,and sorry if i start immediatlay annoy you,but i think you can be the right person
for my almost particular request.i m upgrading my marvellous asus 1201n from w 7 64bit to w8.1 64 bit flashed with your
esaustive unlocked bios,everything is VERY fast:the boot and the descktop,but when i connect to internet to install the antivirus
and the antimalweare,panda antimalwera bytes,the bios becomes insable,it s start almost every boot to ask to press F12 to restore
the default set up,i found in another topic that i need to install the nvidia driver to resolve,i did but didn t change at all.i don t know if it s not possible to restore a corrupted bios once done cause a missed driver,even if you install that driver,because the point to restore the bios i was obligated to  reinstall w7 64,and once back i s able to you use ez flash to reflash the bios,the only way to do it.now i m ready to install w 8.1 64bit,but i d anexpert opinion about the bios,mostly if,it s the case,it s possible to prepare a unlocked bios for the w 8.1 64bit.
sorry for annoyng you and for the request,but i saw your previuos solution,and it s really cleaver,so
thanks for your help and will to help people like me,
mauro

I cannot thank you enough for your work, but i have a problem and i'll be very gratefull if could help me a little more.

I can assure you that this BIOS works and the overclocking features also work great, but this BIOS is ustable, and about once a week (using moderatelly) the netbook freezes and i need to reconfigure it again. This never happens with the original BIOS.

I disabled every tweak and i'm using it with only the AHCI enabled (with the original HDD), and it happens at the same frequency.

It's not overclock related, it's not spread spectrum related, i cannot find the solution.
The netbook does not freeze with the original BIOS even under overclock (using oc tuner).

I'm suspecting that a little bit more was changed from the original BIOS that is making it unstable.
Can you just hack the original BIOS to enable the AHCI, even without any option to disable it? (or point us how to do it?)

Again, thank you very much (and sorry about my english).

because above 3,25GB address range is used for installed devices, the usual solution is to switch to 64-bit. Then the Chipset should use Memory remap feature to move the memory addresses higher than 3,25GB to over 4GB space.
But in your netbook there's no such option. Meaning I can't unlock it. If someone had a datasheet to the ION chipset, it would be easier to make this.
here is the intel 330 datasheet http://www.intel.com/content/www/us/en/p...sheet.html posted by madz

if you could make this bios perfect by adding the missing Memory remap feature, then we would squeeze all power from this little champ, thanks for all your work on the ahci version.
