Bios Mods -The Best BIOS Update and Modification Source

Hi,

Would it be possible to unlock AHCI in the Asus Eee PC 1000HG Bios?

The original last Bios 0703 and other informations can be found on:
http://support.asus.com/download.aspx?SL...shedid=n/a
and is attached too.

Many thanks in advance!

I have a first mod for it, i hope i can upload later for you to test.

Hi Camilo,

that's really great. I would like to test your mod.

Ok,

Try it, and tell me if you see the AHCI setting in "Configure SATA as" option that i have put on Onboard devices configuration. [attachment=3638]

Hi Camilo,

I flashed your modded BIOS on my Asus Eee PC 1000HG without any problemes.
But unfortunately I can't find "Configure SATA as" option under "Onboard devices" configuration.
Can you help once again please?

Ok, i see, routine had another check.

Try this one

Hi Camilo,

many thanks for your work.
After flashing the modded BIOS "Configure SATA as" exists under "Onboard devices".
I changed it to "AHCI".
But it seems, that it does not activate AHCI. There were no automatic driver changes after the first Windows 7-reboot. Also the AS SSD Benchmark still shows "intelide"-mode.
Maybe the reason is another missing BIOS-setting: "ATA/IDE Configuration"?
Similar like here: http://www.bios-mods.com/forum/Thread-Pr...3#pid25453
Do you have an idea to fix the problem?

Many thanks in advance.

The entire IDE configuration form is missing, the setting you refer to is the Disbled/Compatible/Enhanced setting for the controller, the IDE/AHCI/RAID selection is supposed to be effective only with Enhanced mode. I will try to exchange another useless setting with that one in the bios.

Hmmm, i bet this one will do the trick

Hi Camilo,

great, your new mod does the trick! You're really a big expert - my deep and honest respect.

The AHCI-mode with your modded BIOS speeds up the SSD of my good old Asus Eee PC 1000HG!

So I think it will make sense to replace the old CRUCIAL M225 with a newer and bigger CRUCIAL M4 - SSD.

Have a nice day!
