Acer Laptop with Phoenix BIOS: BIOS MOD Request

[Chaosstorm]

Have you flashed your notebook with the modified BIOS? No problem, you can post it in the W860 thread.

Yes I have, and it has more options then I expected ^^

It is either the new CPU is faulty OR it doesn't supported at all. CPU microcode update won't be able to fix either of the problem.

When you said "it restarts itself once then shut down itself with tl-68"; at the point before "it restart itself", did it managed to load windows OR at least you see POST at all?

kizwan ,does this problem involved with cmos restart.
i searched cmos battary or jumper in board i cant find it?!

I am not sure if it is right place to post this issue but it seems to me that I need also a modified bios
I have a small issue with my Acer Aspire 9300 notebook.
I have replaced my old Hitachi HDD 160 GB 5400 RPMs with new Hitachi 250 GB 7200 RPMs HDD. After this the following issue appeared:

I have dualboot system - Linux and Windows, I tried both boot loaders - grub and windows loader - this occurs independently with both. Some times grub errors out:

error> out of disk

I reboot the machine and some time this error reoccurs, some times grub menu appears but then while booting Ubuntu reports that it is not able to find the /home partition. I tested this HDD on other PC - it works fine. Old smaller HDD also works fine. So I suppose that my bios is not always correctly working with large HDD and this causes boot loaders not to be able to locate the entire disk or some of its partitions. I have upgraded bios to latest version:

ftp://ftp.acer-euro.com/notebook/asp...bios/v1.20.zip

But this did not solve the issue.

Can anyone let me know if it is possible to some how modify the BIOS or patch it to support large harddrive?

Any help appreciated!

I have described this issue in the following topic also:

Acer Aspire 9300 is not always able to boot with large harddrive

I highly doubt it. However, there is no harm to try it. The CMOS/RTC battery should be near the CD-ROM connector on the motherboard. The battery is likely covered with a film/cover (please refer to picture below)

@Zox,

Cross posting is not allowed ( forum rules ). Sorry, this kind of mod is not supported. Your notebook does support 250GB HDD, which means BIOS mod is unnecessary.

I have a ACER ASPIRE 7730G, 9600m GT 512 MB and CPU T9400 2*2,53 GHz.

Its possible to create an open BIOS based on 0,3636?

I want SLIC 2.1, VT and an open menue to change Fanspeed , FSB and so on.
Can u use the Tool "ACPI DSDT Patcher" to modify?

Many questions, i know. But i hope u can help me.

Hello

Thx for your help.

The point "unlocked EIST" is great!

When i want to use the "ThrottleStop" programm, i have to start this every time or the setting will be copied in the Windows system to deactivate it permanetly?

So, now i will wait for your great work!

This is modified BIOS image for Aspire 7730G. It is based on BIOS v3636.
Aspire 7730G BIOS_3636 MOD.rar
- Enhanced Intel SpeedStep Technology (EIST) unlocked - for enabling dual-IDA using ThrottleStop.

NOTES: I have unlocked other menu as well. Please be careful with it. If your computer doesn't boot after changing something in the sub-menu, you will need to disconnect the CMOS/RTC battery to reset CMOS back to default. To do so, you will need to open your notebook casing.

Please make sure your notebook can recover corrupted BIOS with CRISIS disk before flashing BIOS with this modified BIOS image. I will not responsible for any problem. Good luck.

There is no modified BIOS for Aspire 7552G yet. Only pictures of hidden options. I will modified it for you as soon as possible. For the meantime, make sure your notebook can recover corrupted BIOS with CRISIS disk. There is new BIOS available at Acer support website, version 1.12. Do you want me modified the latest BIOS?

Just boot with the USB stick (DOS bootable) & run the .BAT file. Please let me know how it goes. If you can post the screenshot of the ThrottleStop running on your notebook after BIOS flash, that would be great.
